ety-related portions meet position C.2 of Regulatory Guide 1.29 and position C.6 of Regulatory Guide 1.13. In meeting Criterion 2, the applicant has also designed the systems to meet the guidelines of NUREGs 0554 and 0612 as they relate to protection against natural phenomena. 9.1.5-5 Rev. 0 - July 1981 2. The requirements of General Design Criteria 4 and 61 are met as they relate to prevention of internally generated missiles that could prevent safe shutdown, cause an unacceptable release of radioactivity, a criticality accident or the inability to cool the fuel in the reactor vessel or spent fuel storage pool. To meet Criteria 4 and 61 the applicant designed the systems in accordance with positions C.3 and C.5 of Regulatory Guide 1.13 and followed the guidelines of NUREGs 0554 and 0612 and followed industry standards ANS 57.1/ ANSI N208 -and ANS 57.2/ANSI N210 in the system design. 3. The requirements of General Design Criterion 5 are met since. any single failure will not impair the safety function of the overhead heavy load handling system nor prevent the safe shutdown and cooldown of either or both units. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commissions Regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission Regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced Regulatory Guides and NUREGs. VI.
