Description

The U.S. Nuclear Regulatory Commission (NRC) is seeking potential vendors to provide development, maintenance, and support for the Symbolic Nuclear Analysis Package (SNAP) framework. The scope of work includes core plugin maintenance, sustainment and user support, and visualization tool development. The NRC requires vendors to have technical experience and proficiency in developing complex Java-based plugins, knowledge of NRC's safety analysis codes, and experience in developing scientific data visualization tools. The contract will be a long-term agreement, and the NRC is looking for vendors who can provide seamless operation of the NRC-owned plugins, adapt to ongoing updates in the underlying physics codes, and continue development of the GRAVE Plot tool. Key aspects of the job include: • Core plugin maintenance and updates to ensure backward compatibility and regression testing • Sustainment and user support for mature plugins, including production of Section 508-compliant technical tutorial videos • Visualization tool development, including UI refinements, new plot format support, and Python API integration • Technical experience and proficiency in developing complex Java-based plugins • Knowledge of NRC's safety analysis codes, specifically TRACE, PARCS, MELCOR, MACCS, and FAST • Experience in developing scientific data visualization tools and creating technical, Section 508-compliant tutorial videos

Budget estimate

$500,000 – $2,000,000

The budget for this opportunity is difficult to estimate, as the document does not provide a specific dollar amount or range. However, based on the scope of work and the fact that it is a long-term contract, it is likely that the budget will be substantial. The budget may be influenced by factors such as the vendor's experience and expertise in developing complex Java-based plugins and scientific data visualization tools, the level of support and maintenance required, and the number of plugins and tools to be developed and maintained. A rough estimate for the budget could be in the range of $500,000 to $2 million per year, depending on the scope and complexity of the work. However, this is highly speculative and should be taken as a rough order of magnitude rather than a firm estimate.
