CFR Title: 

Content:
in a harsh environment are environmentally qualified and are capable of performing their intended safety function. 2. Consistent with 10 CFR 50.49(e)(4), 10 CFR 50.49(e)(6), 10 CFR 50.49(e)(7) 10 CFR 50.34(b)(3), 10 CFR 52.47(a)(5), 10 CFR 52.79(a)(3) and 10 CFR 52.157(e) the applicant shall identify the types of radiation, the 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 radiation environment must be based on the type of radiation, the total dose expected during normal operation over the installed life of the equipment, and the radiation environment associated with the most severe design basis accident during or following which the equipment is required to remain functional. The applicant shall identify whether the equipment is subject to being submerged. The applicant shall identify for which equipment synergistic effects (e.g., temperature increases following a DBE) must be considered based on when these effects are believed to have a significant effect on equipment performance. The applicant shall list all assumptions used in the calculation. 3. Compliance with GDC 1, “Quality Standards and Records,” requires that components important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety function to be performed. GDC 1 is applicable to this Section since it includes requirements for quality standards that must be met, and records that must be kept concerning the quality standards for design, fabrication, erection, and testing of components important to safety. Components in the scope of this SRP Section that are subject to environmental design and qualification must have auditable records to document that environmental design and qualification requirements have been met. Meeting GDC 1 provides
