S The LLHS provides for handling of fuel assemblies and light loads like control rods, burnable poison rods, and flow-limiting orifices. The general objective of the review is to confirm that the LLHS design precludes system malfunctions or failures that could cause criticality accidents, a release of radioactivity, or excessive personnel radiation exposures. There are variations in the designs of proposed handling systems; hence, there are variations in system requirements and the type and number of loads handled. For the purpose of this review, the LLHS does not include equipment used to handle heavy loads (i.e., weights exceeding that of one fuel assembly and its handling tool). The procedures listed here are used in the construction permit or early site permit (ESP) review for whether LLHS design criteria and bases and the preliminary LLHS design described in the SAR meet the acceptance criteria of subsection II of this SRP section. For operating license (OL) or COL reviews, the procedures verify whether the design criteria and bases are implemented appropriately in the LLHS final design. The reviewer will select and emphasize 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. 1. The LLHS system performance requirements are reviewed for whether they cover the handling system concept used in the design and describe the component and subsystem functions within the integrated system. The reviewer verifies whether the LLHS physical arrangement for stored fuel and fuel handling areas has been described sufficiently to establish that the various handling operations can be performed safely.
