Symbolic Nuclear Analysis Package (SNAP) Development, Maintenance, and Support Follow-On
Contact and place of performance
PEREZ-ORTIZ, ARACELIS
Rockville, MD 20852
USA
THE U.S. NUCLEAR REGULATORY COMMISSION (NRC) is issuing this Sources Sought Synopsis as a means of conducting market research or as a market survey to determine the availability of potential qualified vendors with the technical capability to provide all management, supervision, administration, and labor for the project titled “Symbolic Nuclear Analysis Package (SNAP) Development, Maintenance, and Support.&rdquo...
View moreThe objective of this follow-on contract is to ensure seamless operation of these NRC-owned plugins, adapt to ongoing updates in the underlying physics codes, provide sustained support for mature plugins, and continue development of GRAVE Plot — an NRC-owned scientific data visualization tool (successor to APTplot) used in conjunction with SNAP workflows.
Scope of Work Summary
The anticipated scope includes:
Required Capabilities
The purpose of this announcement is to provide potential sources the opportunity to submit information regarding their capabilities to perform work for the NRC free of conflict of interest (COI). For information on NRC COI regulations, visit NRC Acquisition Regulation Subpart 2009.5 (http://www.nrc.gov/about-nrc/contracting/48cfr-ch20.html).
All interested parties, including all categories of small businesses are invited to submit a response. The capabilities package submitted by a vendor should demonstrate the firm’s ability, capability, and responsibility to perform the principal components of work listed. The response should also include past performance/experience regarding projects of similar scope listing the project title, general description, the dollar value of the contract, and name of the company, agency, or government entity for which the work was performed.
If significant subcontracting or teaming is anticipated, organizations should address the administrative and management structure of such arrangements. Submission of additional materials such as glossy brochures or videos is discouraged.
How to Respond to This Sources Sought Notice
If your organization has the capability and capacity to perform, as a prime contractor, one or more of the services described in this notice, then please respond to this notice and provide written responses to the following information. Please do not include any proprietary or otherwise sensitive information in the response, and do not submit a proposal. Proposals submitted in response to this notice will not be considered.
a. SNAP Architecture Expertise: Describe your technical experience and proficiency developing complex Java-based plugins specifically designed to integrate with the SNAP core architecture.
b. Nuclear Code Knowledge: Describe your knowledge of and familiarity with NRC’s primary safety analysis codes, specifically TRACE, PARCS, MELCOR, MACCS, and FAST. How would your team manage unpredictable, patch-driven release schedules from these external code development teams to ensure timely plugin updates?
c. Visualization and Plotting Tools: Provide examples of your experience developing scientific data visualization tools. Specifically, address your capability to build robust User Interface (UI) interfaces and design/implement a Python API for automated plotting (similar to the requirements for GRAVE Plot).
d. Sustainment and Training: Describe your approach to providing long-term sustainment for a portfolio of mature plugins (e.g., job streaming, HPC/SLURM integration) while simultaneously creating technical, Section 508-compliant tutorial videos for end-users.
e. Pricing Strategy: Given that external code patches (like TRACE, MELCOR, MACCS, or FAST) can be unpredictable, what is your experience with managing this type of work under a Firm-Fixed-Price (FFP) structure versus a Labor-Hour structure? Which tasks within this scope do you believe are most suitable for FFP?
Interested organizations responding to this Sources Sought Synopsis are encouraged to structure capability statements in the order of the areas of consideration noted above. All capability statements sent in response to this notice must be submitted electronically, via e-mail, to [email protected], either MS Word or Adobe Portable Document Format (PDF), within 30 calendar days from the date of publication of this notice. The subject line of the transmittal email must reference the notice ID number APP-26-RES-0016.
DISCLAIMER AND NOTES: Any organization responding to this notice should ensure that its response is complete and sufficiently detailed to allow the Government to determine the organization’s potential capability and capacity to perform the subject work. Respondents are advised that the Government is under no obligation to acknowledge receipt of the information received or provide feedback to respondents with respect to any information submitted. After a review of the responses received, a pre-solicitation synopsis and solicitation may be published in SAM.gov. However, responses to this notice will not be considered adequate responses to a solicitation.
The Nuclear Regulatory Commission (NRC) Office of Nuclear Regulatory Research is conducting market research to identify qualified vendors for the Symbolic Nuclear Analysis Package (SNAP) Development, Maintenance, and Support Follow-On project. This requirement involves providing management, administration, and labor for the continued development, maintenance, and sustainment of the NRC’s suite of plugins and plotting tools within the SNAP framework. Key objectives include ensuring the seamless operation of NRC-owned plugins—including TRACE, PARCS, MELCOR, MACCS, and FAST—adapting to updates in underlying physics codes, and continuing the development of the GRAVE Plot scientific data visualization tool.
The anticipated scope of work encompasses core plugin maintenance through routine and patch-driven updates, long-term sustainment of mature plugins, and the production of Section 508-compliant technical tutorial videos. Vendors must demonstrate technical proficiency in Java-based plugin development, knowledge of the NRC’s safety analysis codes, and experience in building robust user interfaces and Python APIs for automated plotting. All services are to be performed in Rockville, Maryland, under NAICS code 541511 for Custom Computer Programming Services.
This sources sought notice, identified by solicitation number APP-26-RES-0016, requires interested parties to submit capability statements that address their SNAP architecture expertise, pricing strategies for unpredictable code updates, and ability to perform work free of organizational conflicts of interest. Responses must be submitted electronically to PEREZ-ORTIZ, ARACELIS by the deadline of July 8, 2026. One attachment, a PDF document titled APP-26-RES-0016 SSN_SNAP.pdf, was included with the notice published on June 8, 2026.
