quences 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 hence subject to the acceptance criteria presented in this SRP section. The general objective of the review is to confirm that the OHLHS design precludes system malfunctions or failures that would prevent safe shutdown of the reactor, or 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. The procedures listed here are used in the construction permit (CP) review to determine that the OHLHS design criteria and bases and the preliminary OHLHS design described in the SAR meet the acceptance criteria given in subsec- tion II of this SRP section. For operating license (OL) reviews the procedures are used fo verify that the design criteria and bases have been appropriately implemented in the OHLHS final design. Upon request by the ASB, the coordinating review branches will provide input for the areas of review in subsection I of this SRP section. The ASB obtains and uses such input as required to assure that this review procedure is complete. The reviewer will select and emphasize material from this SRP section, as may be appropriate for a particular case. 1. The system performance requirements for the OHLHS are reviewed to determine that they cover the handling system concept used in the design, and describe the component and subsystem functions within the integrated systems. The performance requirements should also define any degradation considered for components and describe the procedures that are followed to detect and correct degraded conditions. 2. The performance specifications required as part of the design and described in the SAR are reviewed to determine that the design, material selection, manufacturing, installation, testing, and operating procedures equal or
