applicant's design also meets the requirements of General Design Criterion 54 as related to leak detection, isolation, and performance testing for system piping penetrating containment. The bases for acceptance is that the design meets positions C.3 and C.5 through C.12 of Regulatory Guide 1.96. (If an alternative to an MSIVLCS is proposed to address steam line isolation valve leakage, this section of the SER should instead briefly indicate that an acceptable alternative to the MSIVLCS has been provided to control offsite consequences resulting 6.7-11 DRAFT Rev. 3 - April 1996 from leakage past the steam line isolation valves in the event of a LOCA and that findings related to the acceptable alternative are described in other sections of the SER.)54 For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff’s evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP section.55 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plan for using this SRP section. This SRP section will be used by the staff when performing safety evaluations of license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR 52. Except in those 56 cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of compliance with Commission regulations. The provisions of this SRP section apply to reviews of applications docketed six months or more after the date of issuance of this SRP section.57 Implementation schedules for conformance to parts of the method discussed herein are contained in the
