HS will perform their functions safely. 3. GDC 4 requires protection for SSCs important to safety against the effects of internally-generated missiles. GDC 4 applies to SRP Section 9.1.5 because GDC 4 specifies protection against the effects of internally-generated missiles (i.e., dropped loads). A dropped heavy load in a critical area could cause a release of radioactive materials, a criticality accident, or inability to cool fuel within the reactor vessel or spent fuel pool or could prevent safe shutdown of the reactor. Position C.5 of RG 1.13 provides guidance for meeting these requirements in spent fuel storage areas. These requirements provide assurance that SSCs associated with the OHLHS will perform their functions safely. 4. GDC 5 requires that SSCs important to safety not be shared by nuclear power units unless such sharing can be shown not to significantly impair their ability to perform safety functions, including, in an accident in one unit, an orderly shutdown and cooldown of the remaining units. GDC 5 applies because the OHLHS may be shared in multiple-unit plants. The OHLHS must be designed such that credible load handling events do not adversely affect the safe storage of irradiated fuel or the capability to shut down and cool down any operating unit at the site. 9.1.5-5 Revision 1 - March 2007 These requirements provide assurance that personnel working with the OHLHS work under adequately safe conditions with exposure to radiation within safe limits. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. The general objective of the review is to confirm
