Content:
ion monitoring requirements, replacement part identification, and applicable design changes and modifications; (6) development of plant procedures for reviewing equipment performance and environmental qualification operational activities, and for trending the results to incorporate lessons learned through appropriate modifications to the environmental qualification operational program; and (7) development of plant procedures for the control and maintenance of environmental qualification records. 24. For COL reviews, Section 13.4, “Operational Program Implementation,” describes the operational program and proposed implementation milestone(s) for the environmental qualification program is reviewed in accordance with 10 CFR 50.49. The implementation milestone for the environmental qualification program is to have all qualification requirements met prior to the loading of fuel. Implementation is required by a license condition. 25. Consistent with the requirements of 10 CFR 50.49(e)(4) and 10 CFR 50.49(e)(6), and the guidance contained within RG 1.206 subsection C.I.3.11.5, the applicant shall identify the type of radiation dose and dose rate used to determine the radiation environment and indicate the extent to which estimates of radiation exposures are based on a radiation source term that is consistent with NRC staff-approved source terms and methodology. The applicant shall identify whether the equipment is subject to being submerged. The applicant should tabulate the pre-DBE neutron (inside containment, where applicable), beta and gamma exposures separately for each item of equipment and list the average energy of each type of radiation, and beta and gamma exposures post DBE. For engineered safety features (ESF) systems outside containment, the applicant should indicate whether the radiation estimates account for factors affecting the source term such as containment leak rate, meteorological dispersion (if appropriate), and operation of other ESF systems.
