erlocks and devices, and the load handling instructions, inspections, maintenance and testing, provide adequate system control for the specific procedures of handling operations, if the redundancy and diversity needed to protect against malfunctions or failures are provided, and if the design conforms to the relevant requirements of the following regulations: 1. General Design Criterion 2, as related to the ability of structures, equipment, and mechanisms to withstand the effects of earthquakes. Acceptance is based in part on meeting position C.1 of Regulatory Guide 1.29 for safety-related equipment and position C.2 for nonsafety- related equipment, and positions C.1 and C.6 of Regulatory Guide 1.13. 2. General Design Criterion 4 as it relates to protection of safety-related equipment from the effects of internally generated missiles (i.e. dropped loads). Acceptance is based in part on meeting positions C.3 and C.5 of Regulatory Guide 1.13. 3. General Design Criterion 5 as related to the sharing of equipment and components important to safety. 4. General Design Criterion 61 as related to the safe handling and storage of fuel. Other specific criteria necessary to meet the relevant requirements of General Design Criterion 2, 4 and 61 are as follows: a. NUREG-0554 (formerly proposed Regulatory Guide 1.104 and Branch Technical Position ASB 9-1) b. NUREG-0612 c. ANS 57.1/ANSI N208 d. ANS 57.2/ANSI N210 9.1.5-3 Rev. 0 - July 1981 III. REVIEW PROCEDURES The OHLHSs are provided for handling heavy loads i.e. loads whose weight exceeds that of one fuel assembly and its associated handling device such as a reactor vessel head, internals, shield plug segments and spent fuel casks. Due to variations in plant designs, the ASB shall review the analyses made of the potential consequences that could follow the dropping of each heavy load at any point along its path of travel. In those cases where the consequences are unacceptable the load is to be considered a critical load and
