Draft Revision 4 – June 2013 Compliance with GDC 61 provides reasonable assurance that releases of radioactive materials and unacceptable personnel radiation exposures from damage to irradiated fuel will be avoided. 4. GDC 62 requires prevention of criticality in the fuel handling and storage system by physical systems or processes, preferably by geometrically safe configurations. GDC 62 requirements ensure that fuel handling and storage SSCs will be controlled so criticality will not be reached, ensuring the safety of the public. ANSI/ANS 57.1-1992 provides guidance for meeting these requirements. Compliance with GDC 62 provide assurance that the LLHS will operate under adequately safe conditions and avoid criticality accidents and consequent releases of radioactive materials from damage to or changes in fuel, ensuring acceptable levels of personnel radiation exposure. III. REVIEW PROCEDURES 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 to determine whether LLHS design criteria and bases and the preliminary LLHS design described in the Safety Analysis Report (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
