R--Plant Model Development for Sequoyah Nuclear Plant

The contract pertains to the development of a plant-specific computational model for the Sequoyah Nuclear Power Plant using the TRAC/RELAP Advanced Computational Engine (TRACE) and the Purdue Advanced Reactor Core Simulator (PARCS). The objective is to create an advanced, integrated plant model that accurately simulates reactor behavior under normal and off-normal conditions, supporting safety analysis, operational planning, and regulatory review. The work requires leveraging these industry-standard simulation tools to replicate the unique design characteristics, thermal-hydraulic systems, and core geometry of the Sequoyah facility, ensuring high fidelity and regulatory compliance. The model will be validated against plant data and operational experience to guarantee reliability and utility for nuclear safety applications. The solicitation, issued by the Nuclear Regulatory Commission under number 31310026R0015 and classified under NAICS code 541690, was posted on May 15, 2026, with a response deadline of the same day at 6:00 PM Eastern Time. The award will be managed by the NRC office in Rockville, Maryland, with Jeffrey R. Mitchell as the primary point of contact. There is no set-aside designation specified, indicating this is an open competition. The performance location is not defined, suggesting the work may be performed remotely or at the contractor’s facility, with deliverables submitted electronically to the NRC. The model development will serve as a critical tool for enhancing the regulatory foundation for plant operations and potential license renewals or modifications.
