Content:
usion area, low population zone, and population center distance should be determined. Further, radiation exposure criteria stipulated in 10 CFR Part 100 provide reference values to be used in the site suitability determination based on postulated fission product releases associated with accidental events. 10 CFR Part 100 is applicable to this section because it specifies the methodology for calculating radiation exposures at the site boundary for postulated accidents or events such as loss of a reactor coolant pump. For transients having a moderate frequency of occurrence, any release of radioactive material must be such that the calculated doses at the site boundary are a small fraction of the 10 CFR Part 100 guidelines. A small fraction is interpreted to be less than 10 percent of the 10 CFR Part 100 reference values. For the purpose of this review, the radiological consequences of a RCP rotor seizure or shaft break must include consideration of the containment, confinement, and filtering systems. The applicant's source terms and methodologies with respect to gap release fractions, iodine chemical form, and fission product release timing should reflect NRC-approved source terms and methodologies such as those contained in NUREG- 1465. Meeting this requirement provides a level of assurance that, in the event of a transient initiated by a reactor coolant pump rotor seizure or shaft break, radiation exposures at the site boundary will not exceed a small fraction of the reference values specified in 10 CFR Part 100.43 III. REVIEW PROCEDURES The procedures below are used during both the construction permit (CP), and operating license (OL), and combined license (COL) reviews. During the CP review, the values of system 44 DRAFT Rev. 3 - April 1996 15.3.3-8 parameters and setpoints used in the analysis will be preliminary in nature and subject to change. At the OL or COL review stage, final values should be used in the analysis, and the reviewer 45 should compare these to
