Overview
The NSUF mission is to facilitate the advancement of nuclear science and technology by providing nuclear energy researchers with access to world-class capabilities at no cost to the researcher. This mission is enabled by a consortium of partners that make available state-of-the-art experimental irradiation testing, post irradiation examination (PIE), and INL high performance computing (HPC), as well as technical and scientific assistance for the design and execution of projects. Access to NSUF capabilities is granted through competitive proposal processes.
The Rapid Turnaround Experiment (RTE) award process offers an avenue for researchers to perform irradiation effects studies of limited scope on nuclear fuels and materials of interest utilizing NSUF facilities, with the goal of providing timely results to the research community. Therefore, RTEs are confined to the scope outlined in the proposal and should be completed within nine months of award notification. While NSUF is committed to supporting the successful completion of awarded RTE projects, timely participation from the principal investigator (PI) is essential. Failure to provide samples promptly or to complete the project within the nine-month timeframe may result in cancellation, subject to the NSUF Director’s review. To help achieve this timeline, the NSUF provides the following guidelines which have been proven effective based on experience:
- Post-irradiation examination (PIE) should be scheduled within three months.
- Samples should be sent to the PIE facility within five months.
- Project scope should be completed within nine months.
RTE proposals are typically solicited and awarded three times per year. They are reviewed and evaluated for technical merit, relevancy, and feasibility, as described in the RTE Technical Review Process and must support the DOE Office of Nuclear Energy mission. The number of awards is dependent on the availability of funding. After the award announcements are made, NSUF may share information from the awarded project that is of scientific interest to the research community. This may include the names, institutions, and expertise of the PI and team members, as well as the project summary, hypothesis, and descriptions of the work, equipment, and data from the application form. Depending on the privacy settings in the user profile, the email address and phone number of the PI or their designated point of contact may also be displayed. NSUF will not disclose the project narrative or any other information that could negatively impact publications resulting from the awarded research project. Since the goal of all awarded projects is to generate scientifically relevant information for the research community, it is crucial that no proprietary, sensitive, or confidential information be included in the RTE proposal.

Rules for SuperRTE Proposal Submission
Failure to meet any of the rules listed below may result in disqualification of the proposal.
January 2025 – Clarification to Rule 5 for proposals involving material development. Clarification to Rule 16 to exclude NSUF partner facility points of contact as the collaborator requirement for proposals from non-U.S. institutions.
September 2024 – Update to Rule 5 to provide clarity on the requirement for RTE awards to create scientific data within the planned scope of work. Update to Rule 17 to suggest use of the NSF Biographical Sketch template for the CV.
Content:
- The study proposed must be original and shall not duplicate any work currently funded by a DOE, or other Federal, program or project, including Laboratory Directed Research and Development (LDRD).
- The scope of the RTE proposal must be unique and not overlap with any past, current or proposed scope in an open funding call.
- The proposed scope of work to be funded by the NSUF must have the potential to produce data at the requested NSUF facilities that will lead to a scientific or engineering outcome suitable for publication that will be attributed to the NSUF.
Facilities:
- While complying with all other rules, a proposal may request NSUF funding for use of NSUF capabilities at up to three partner institutions:
- ONE partner institution for sample preparation and/or shipping;
- ONE partner institution for irradiation; and
- ONE partner institution for post-irradiation examination (PIE).
- Proposals requesting NSUF funding only for sample preparation and/or sample shipment will not be accepted. (Material development is outside the scope of an RTE project and will not be accepted.) Proposals requesting irradiation without an NSUF PIE facility must include significant in situ monitoring of the device under irradiation (e.g., neutron irradiations of instrumentation or ion beam analysis techniques) sufficient to result in a measurable scientific outcome. All proposals must meet the requirements of Rule 3 above.
- NSUF RTE proposals must focus on irradiated or radioactive materials or nuclear fuels research, including in-situ sensor performance characterization. Proposals can include limited non-irradiated structural or cladding reference samples, as appropriate. (When requesting in-situ irradiation measurements, the same facility for irradiation and PIE should be selected.)
Funding:
- The NSUF will only support activities at, and shipping between, NSUF facilities. Shipping expenses from non-NSUF partners will not be covered by the NSUF and will require an external funding source.
- The NSUF does not provide funding to the PI to support salaries, tuition, travel, or other costs typically supported via NE Program R&D funds.
- Applicants must have a source of R&D funding that will fund all components of the proposed project not funded by the NSUF. External funding should be reported with as much detail as possible.
- Completion of all NSUF funded work proposed must require no more than nine months from the date of award.
Applicant:
- Only one principal investigator is allowed per proposal.
- A principal investigator may submit no more than one proposal per RTE call.
- A principal investigator may have only two active RTE projects.
- A project is considered active until a completion report is submitted and approved (please refer to completion report criteria for additional information).
- Proposals are welcomed from principal investigators affiliated with a U.S. university, U.S. government laboratory, U.S. entity or foreign entity incorporated in the U.S.
- Proposals from principal investigators not from a U.S. institution will be accepted as long as the proposal includes a collaborator who is from a U.S. university, U.S. government laboratory, U.S. entity, or foreign entity incorporated in the U.S., and is not an NSUF partner facility point of contact. This collaborator must have a significant role in the experiment or project that supports the RTE. NSUF will contact the U.S. collaborator to verify their role in the project. The roles and responsibilities for each U.S. collaborator should be clearly identified within the 2-page project narrative.
- All proposals must include a 2-page (maximum) project narrative as well as a 2-page curriculum vitae (or equivalent) for the PI and all team members. NSUF encourages applicants to utilize the NSF Biographical Sketch template for the CV format. All documentation is to be prepared using standard 8.5” × 11” paper with 1-inch margins (top, bottom, left, right) and a font size no smaller than Times New Roman 11 point. Narratives exceeding the page length limit will be redacted and any pages exceeding the limit will not be reviewed.
- Proposals must include all publications the PI and co-PIs have produced as a result of any and all previous NSUF funded experiments or projects (RTE, beamline, and CINR).
- Data generated from the work must be made available to the research community in a timely manner. The PI is responsible for the collection, management, and sharing of the research data through a data management plan.
Facility Guidelines for RTE Experiments
The included guidelines are designed to help researchers develop a proposal that can be executed within the RTE schedule and budget. Applicants should work with each facility representative (NSUF Partner Institutions) to ensure that their proposed work (scope, number of specimens, etc.) can be accomplished within the RTE guidelines for that facility. The guidelines are based on the average cost of instrument time at each facility, on a typical work week, and on the assumption that only one instrument is used each day.

For in-situ irradiation measurements (e.g., IVEM, MIBL, I3TEM and University of California-Berkeley), the same facility for both irradiation and PIE should be selected in the application.
Neutron irradiation experiments that require the use of ATR, TREAT, HFIR or MITR in core positions do not qualify for an RTE award due to expense and duration of project.
A cost estimate will be developed based on the requested scope. This cost estimate will be used in evaluation of the proposal. Controlling costs and scope among all proposals helps to ensure that the projects can be completed within nine months from award and helps to maintain fairness for all applicants.
Failure to follow the guidelines, as well as excessively scoped proposals, may render your proposal “not feasible” based on costs alone. Proposals that utilize multiple facilities may result in an estimate that cannot be accommodated within the bounds of a RTE and thus deem the proposal “not feasible.” Principal investigators will receive project specific feedback if the proposal was not recommended for award when deemed “not feasible”.
To maintain the goal of the rapid user facility access program, the progress of awarded RTEs will be periodically monitored by NSUF staff. Any projects that are not making satisfactory progress or have exceeded nine months from the date of award may be subject to cancellation.
RTE Completion Report
A completion report must be submitted by the PI or co-PI within four months of any completed RTE project and must precisely follow the guidance provided. If no completion report is submitted, the RTE project will be considered active. A satisfactory completion report will contain the following:
- summary of both the work completed and the data obtained. In addition, the PI should make appropriate project data available to the research community in a timely manner (see RTE rule #19). Data storage is available through an NSUF data storage system called the Nuclear Research Data System (NRDS). Contact Matt Anderson at: [email protected] for details and access.
- description of the potential impact to the state-of-knowledge.
After submittal, a completion report will be reviewed by the NSUF Program Office staff. If the report is determined to be satisfactory, the project status will be changed to complete. If the report is deemed unsatisfactory, the report will be returned to the PI with comments that will need to be addressed prior to resubmission.
After approval, the completion report will go through a classification and export control review for external release. Once the completion report is approved for external release, it will be posted on the NSUF website under the PI’s project, where it will be accessible to the public.
Applicants will be allowed to prepare, but not submit, a proposal that, if awarded, would create a third active RTE project for a PI. On initiation of the proposal, applicants will be informed that submission of the proposal will not be allowed until a completion report for one of the active projects is approved. Completion reports must be submitted at least two weeks prior to the close of the call to allow time for review. Applicants are encouraged to submit completion reports well in advance of the close of a RTE call as iteration may be required prior to approval.

Frequently Asked Questions
How many active traditional or Super-RTEs can I have at one time?
A PI may only have two active traditional RTE Projects and one SuperRTE project. All RTE projects are considered active until a satisfactory completion report has been submitted and approved. If you currently have two active traditional RTE projects and one active SuperRTE project during an ongoing call, a new proposal may be prepared and saved in the application. However, you will not be able to submit a new SuperRTE proposal until you complete an active SuperRTE project (i.e., a completion report has been submitted and approved). A PI is eligible to submit a SuperRTE proposal if the PI has up to two active traditional RTEs and has none currently under review or has up to one active traditional RTE and has one RTE proposal currently under review.
Once an RTE call is open, what assistance can NSUF provide me with my application?
The RTE Administrator, Kathy Swartz ([email protected]), can assist with submittal questions and issues. During an open RTE call, you should contact any of the NSUF facility contacts for assistance with proposal feasibility. NSUF facility staff and facility contacts cannot help with the technical aspects of a proposal in order to ensure fairness during the review process.
Can someone review my Super-RTE proposal prior to submission?
The NSUF Chief Scientists, Keith Jewell ([email protected]) and Rongjie Song ([email protected]), can provide general advice, but not a detailed review. Continue to watch the NSUF website for updates on the RTE rules and guidelines and upcoming informational webinars and individual Q&A opportunities.
Is there a time or dollar limit on my award?
There is no specific target value for the RTEs. As applicants will not know the cost of their proposal, NSUF has posted a set of Facility Guidelines for traditional RTE experiments that are designed to help researchers develop a proposal that can be executed for within less than the suggested target. The guidelines are based on the average cost of instrument time at each facility. The guidelines are based on a typical work week at each facility and assume that only one instrument is used each day. If you request more than one NSUF facility for your project, please note that all facility costs are considered as part of the total target. It is recommended that you contact the specific NSUF facility or facilities you wish to use to help you develop a proposal that meets the dollar target guideline.
How do I know how "big" of a Super-RTE I can propose?
The NSUF lists Super-RTE Facility Guidelines for all the facilities available in the Super-RTE call. This is expressed in “weeks” or “days.” For the best results, an investigator should contact the NSUF partner facility point of contact when developing a proposal in order to match the right number of specimens and tests to the allowed days at each facility.
How long is the Super-RTE application?
The Super-RTE application has 6 short sections. These sections include: principal investigator information, team member information, experiment details, technical abstract (less than 500 words), NE program relevance abstract (less than 500 words), and a proposal narrative (3-page limit).

Can the NSUF grant a no-cost extension to my project?
Per Super-RTE guidelines, awarded traditional RTEs must be completed within twelve months of the date of award. There is not a formal NSUF process to extend work beyond twelve months. If a project extends beyond twelve months, PIs should work with the NSUF RTE Administrator, Kathy Swartz ([email protected]), to ensure that a project is completed as soon as possible. NSUF may cancel a project if is not completed within the twelve-month timeline.
What is the status of my Super-RTE application?
The status of an RTE application can be found on the Proposal page. From there, check the status column in the “My Proposals” box.
If I resubmit a proposal after addressing reviewer comments, will the same reviewers be assigned to my proposal?
Reviewers are assigned based on expertise, availability, and lack of any conflicts of interest. There is no guarantee that the same reviewers will be assigned.
Where can I find current Super-RTE call information?
The Super-RTE page is regularly updated. Please contact us at [email protected] if the page does not answer your question. You can also visit the Communications page to sign up for email notifications.
I received the reviewer comments on my proposal and one reviewer appears very positive and the other did not. How does NSUF deal with reviews that seem to disagree?
NSUF leadership and the competitive awards team meet and evaluate all of the reviews, relevancy, technical, and feasibility, for each proposal. If a set of reviews is in disagreement, NSUF assesses the quality of the reviews and may ask for an additional review in that area. Two reviewers can legitimately disagree. If both reviews are deemed to be high-quality, they may be allowed to stand, even if they appear to be very different. If one of the reviews appears to be lacking, it may be replaced by a third review.
Is there a way to submit a rebuttal for a rejected proposal?
There is no formal process. However, you may always apply in the next award round.
I see that the high-flux NSUF reactors are not available for RTE calls. How can I get my specimens irradiated and how can I ensure I'm choosing the proper reactor?
These questions should be directed to the NSUF Chief Scientists, Keith Jewell ([email protected]) and Rongjie Song ([email protected]), who can provide further information and points of contact, as appropriate.
Can I request an irradiation-only RTE if I intend to perform the PIE with other funding?
No, Rule 3 states that “The proposed scope of work to be funded by the NSUF must have the potential to produce data at the requested NSUF facilities…” Since 2018, RTEs can include both irradiation and PIE, so there is no longer any reason to exclude PIE from an RTE. Additional PIE can be performed following the completion of the RTE that can build upon the results of the NSUF-supported work. In that case, NSUF should be acknowledged for the irradiation portion of the RTE.
I have an idea for a novel material or material application. Can I get RTE support to develop this idea?
NSUF RTEs are intended to support testing and characterization of nuclear fuels, materials and sensors. They are also small in scope and need to be accomplished in a few months after award. Because of these restrictions, material development is most likely outside the scope of an RTE. An investigator could certainly perform a test or series of tests on a novel material, but an NSUF RTE is not the proper tool to develop a fabrication technique, for example.
Is there a way to access the NSUF materials library outside of the RTE calls?
The Nuclear Fuels and Materials Library (NFML) samples can be assigned based on discretion of NSUF program leadership. Contact Kelly Cunningham ([email protected]) for details on the process and visit this page for more information.
NSUF offers access to INL high performance computing (HPC) as part of the RTE call. How do I get support for modeling and simulation (M&S)?
RTE scope should focus on the experimental side and not focus on the M&S aspects. NSUF can only provide limited staff support for M&S as part of a CINR award. Consider using the Nuclear Energy Researcher Database (NERD) tool to find a collaborator that can help with M&S.
My question wasn’t answered, who do I contact?
You can email [email protected] with any further questions.
