Content:
t will transfer heat from the reactor core in the event of a LOCA, and that suitable redundancy of components and features is provided so that the safety function can be accomplished assuming a single failure. GDC 35 specifies that an emergency core cooling system be installed in all nuclear power reactors. SRP Section 15.6.5 specifies the analytical procedures that are to be followed to establish that the ECCS will function to meet acceptance criteria specified in 10 CFR 50.46. 15.6.5-8 Revision 3 - March 2007 10 CFR Part 50, Appendix K and Regulatory Guide 1.157 provide guidance on calculational procedures needed to demonstrate compliance with the acceptance criteria. Meeting the requirements of GDC 35 will provide assurance that following a LOCA that the reactor core will remain in a coolable geometry and offsite consequences will be within the guidelines specified in 10 CFR 100 or 10 CFR 50.67. 4. Compliance with 10 CFR 100 or 10 CFR 50.67, Reactor Site Criteria, describe criteria that guide the Commission in its evaluation of the suitability of proposed sites for nuclear power and testing reactors. 10 CFR 100 or 10 CFR 50.67 specify radiation dose guidelines that should not be exceeded in the event of postulated accidents including LOCAs. In order to satisfy the requirements of 10 CFR 100 or 10 CFR 50.67, the applicant must demonstrate that the offsite doses resulting from various accidents presented in the SAR are within the guideline values. Meeting the guideline doses is achieved by a combination of engineered safety features installed in the nuclear facility, an effective emergency core cooling system, and siting the nuclear plant in an area that does not exceed population density requirements. Meeting the nuclear power plant siting criteria provides a level of assurance that the plant will pose no undue risk to the public as a result of the consequences of LOCAs. III.
