Standard Guide for Establishing Surveillance Test Program for Boron-Based Neutron Absorbing Material Systems for Use in Nuclear Fuel Storage Racks In a Pool Environment
SIGNIFICANCE AND USE
4.1 The storage of nuclear fuel in high-density storage racks is dependent upon the functionality and integrity of an absorber between the stored fuel assemblies to ensure that the reactivity of the storage configuration does not exceed the K-effective allowed by applicable regulations. A confirmation test may be required to verify the functionality and integrity of the absorber within the racks. If establishing a surveillance program for newly installed or existing absorber material in fuel racks, the following methods are suggested: (a) coupon monitoring program (if coupons are available); (b) in-situ neutron attenuation test; and (c) other applicable in-situ tests such as visual inspection or drag test.
4.2 This guide provides guidance for establishing and conducting a surveillance program for monitoring the ongoing functionality and integrity of the absorbers.
SCOPE
1.1 This guide provides guidance for establishing a surveillance test program to monitor the performance of boron-based neutron absorbing material systems (absorbers) necessary to maintain sub-criticality in nuclear fuel storage racks in a pool environment. The practices presented in this guide, when implemented, will provide a comprehensive surveillance test program to verify the functionality and integrity of the neutron absorbing material within the storage racks. The performance of a surveillance test program provides added assurance of the safe and effective operation of a high-density storage facility for nuclear fuel. There are several different techniques for surveillance testing of boron-based neutron absorbing materials. This guide focuses on coupon monitoring and in-situ testing.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
