2.0 TECHNICAL EVALUATION
2.1 Integrated Safety Analysis PURPOSE OF REVIEW This LAR analyzes vehicle accidents for normal plant traffic and construction activities and replaces the existing Operating while Construct accident sequences with a new set of accident sequences. The LAR includes supporting calculations to demonstrate that IROFS50a, b, c, d, e, h, i, and j are not required to meet the performance requirements in 10 CFR 70.61.
The purpose of this review is to determine whether the UUSA ISA program will continue to be in compliance with 10 CFR 70, Subpart H, Additional Requirements for Certain Licensees Authorized to Possess a Critical Mass of Special Nuclear Material, should the NRC approve the LAR.
REGULATORY REQUIREMENTS The NRC staff conducted its review of the LAR and supporting calculations to ensure that the requested changes are consistent with the requirements in 10 CFR Part 70, including:
a) The regulations in 10 CFR 70.61 require, in part, that the ISA evaluate compliance with performance requirements. Those requirements specify that the risk of each credible high-consequence event must be limited such that the likelihood of occurrence is highly unlikely, and the risk of each credible intermediate-consequence event must be limited such that the likelihood of occurrence is unlikely.
b) The regulations in 10 CFR 70.62 require, in part, the licensee to establish and maintain a safety program that includes process safety information, an ISA and management measures. The ISA must identify radiological hazards, chemical hazards, facility hazards that could affect the safety of licensed materials and thus present an increased radiological risk, potential accident sequences, the consequence and likelihood of occurrence of each potential accident sequence and each IROFS identified pursuant to 10 CFR 70.61.
c) The regulations in 10 CFR 70.65, Additional content of application, require the licensee to submit an ISA Summary with the amendment that contains specific information to demonstrate compliance with 10 CFR 70.61.
REGULATORY GUIDANCE The NRC staffs review was conducted in accordance with Chapter 3 of NUREG-1520, particularly Section 3.4.3.2 which addresses the regulatory acceptance criteria for the ISA Summary and documentation.
REGULATORY ACCEPTANCE CRITERIA The acceptance criteria for the NRCs review of UUSAs ISA are outlined in Sections 3.4.3.1 and 3.4.3.2 of NUREG-1520, Revision 2. The acceptance criteria in Section 3.4.3.1 pertain
