Background and Objective The U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research (RES), requires continued development, maintenance, sustainment, and user support for its suite of plugins and plotting tools within the Symbolic Nuclear Analysis Package (SNAP) framework. SNAP is a graphical user interface developed and owned by ISL, Inc. that is licensed to the NRC. The NRC has funded and owns specific plugins within the SNAP framework including the TRACE, PARCS, MELCOR, MACCS, and FAST plugins which assist NRC staff and international partners in developing input models and analyzing output for complex nuclear safety codes. The 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: Core Plugin Maintenance: Routine and patch-driven updates to the TRACE, PARCS, MELCOR, MACCS, and FAST plugins to align with external code releases, ensuring backward compatibility and regression testing. Sustainment and User Support: Long-term maintenance of mature plugins (e.g., Engineering Template, SLURM Job Stream, Git Version Control, Uncertainty Quantification) and production of Section 508-compliant technical tutorial videos. Visualization Tool Development: Active continuous development of GRAVE Plot, including User Interface (UI) refinements, new plot format support, and Python API integration. Required Capabilities Technical experience and proficiency developing complex Java-based plugins designed to integrate with the SNAP core architecture. Demonstrated knowledge of NRC s safety analysis codes, specifically TRACE, PARCS, MELCOR, MACCS, and FAST. Experience developing scientific data visualization tools. Specifically, capability to build robust UI interfaces and design/implement a Python API for automated plotting. Demonstrated experience creating technical, Section 508-compliant tutorial videos. Experience and proficiency in Section 508 of the Rehabilitation Act requirements to ensure the creation and delivery of compliant deliverables. 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.
