specified by top- ical reports describing the methods and by staff reports approving the methods. The analysis methods addressed are to include core thermal-hydraulic calculat- ions to establish local coolant conditions, departure from nucleate boiling or boiling transition calculations, and thermal-hydraulic stability evaluation. If an applicant has used previously unapproved correlations or analysis methods, the reviewer initiates an evaluation, either generic or plant specific. Any changes to accepted codes, correlations, and analytical procedures, or the addition of new ones must be reviewed to determine that they are justified on theoretical or empirical grounds. A secondary review is performed by ICSB, HFEB, and PTRB. ICSB will review the functional performance and requirements for the Inadequate Core Cooling (ICC) monitoring system hardware. Emergency procedure guidelines and the information display will be reviewed by PTRB and HFEB, respectively. The results of these reviews will be used by CPB to complete the overall evaluation of the thermal-hydraulic review and will be incorporated into the Safety Evaluation Report (SER). The review of power distribution assumption made for the core thermal and hydraulic analysis is coordinated with the review for core physics calculat- ions, as described in the Standard Review Plan (SRP) Section 4.3, for consistency. The reviewer verifies that core monitoring techniques which rely on in-core or ex-core neutron sensor inputs are reviewed. II. ACCEPTANCE CRITERIA The CPB acceptance criteria are based on meeting the relevant requirements of General Design Criterion 10 (Ref. 1), as it relates to the reactor core being designed, with appropriate margin to assure that specified acceptable fuel design limits are not exceeded during normal operation or anticipated operational occurrences (AOO). Specific criteria necessary to meet the requirements of GDC 10 are as follows: 1. SRP Section 4.2 specifies the acceptance criteria for
