Purpose

The purpose of the Advanced Reactor Content of Application Project (ARCAP) is to develop technology-inclusive, risk-informed and performance-based application guidance. The ARCAP is broader and encompasses the industry-led Technology-Inclusive Content of Application Project (TI-CAP). These projects build on the outcome of the Licensing Modernization Project.

The ARCAP guidance is intended to be used for an advanced reactor application for a combined license, construction permit, operating license, design certification, standard design approval, or manufacturing license. The industry-led TI-CAP's purpose is to develop the content for specific portions of the safety analysis report (SAR) that would be used to support an advanced reactor application. The TI-CAP portion of the SAR will be informed by the guidance found in in NEI 18-04, Revision 1, "Risk-Informed Performance-Based Technology-Inclusive Guidance for Non-Light Water Reactor Licensing Basis Development."

ARCAP supports the near-term advanced reactor applicants under 10 CFR Part 50 and Part 52, and also support the 10 CFR Part 53 rulemaking effort..

Another effort associated with ARCAP and TI-CAP is the Technology Inclusive, Risk-Informed Change Evaluation (TIRICE) process and the Technology Inclusive Management of Safety Case (TIMaSC) process.  TIRICE provides an alternative change evaluation process for determining if NRC approval is required before implementing certain facility changes to reactors that were licensed using the methodologies in NEI 18-04.  The industry’s proposed guidance document for implementing the TIRICE process is NEI 22-05, “Technology Inclusive Risk Informed Change Evaluation (TIRICE): Guidance for the Evaluation of Changes to Facilities Utilizing NEI 18-04 and NEI 21-07.” TIMaSC provides a process for the management of a licensing modernization project-based safety case. Examples of TIMaSC guidance includes how to manage the safety case in the event operating experience indicates reliability or capability targets for safety significant structures, systems, and components (SSCs) are not met or operating experience indicates reliability or capability targets for safety significant SSCs have more than anticipated margin.
