NUREG408OO (Formerly NUREG-75/087) ,^ @ U.S NUCLEAR REGULATORY COMMISSION STANDARD REVIEW PLAN OFFICE OF NUCLEAR REACTOR REGULATION APPENDIX 7-A BRANCH TECHNICAL POSITIONS (ICSB) The ICS8 Branch Technical Positions (BTPs) represent guidelines intended to supplement the acceptance criteria established in Commission regulations and the guidelines provided in regulatory guides and applicable IEEE standards. The BTPs originate in technical problems or questions of interpretation that arise in the detailed reviews of plant designs. The staff must make a judgment in each such case, in order to complete its review of the particular application. Where the same technical problem or question of interpretation arises in several cases, the staff's judgment on the point at issue is formalized in a BTP. The BTP is primar- ily an instruction to staff reviewers that outlines an acceptable approach to the particular issue and ensures a uniform treatment of the issue by staff reviewers. The approaches taken in the BTPs, like the recommendations of regulatory guides, are not mandatory, but do provide defined, acceptable, and immediate solutions to some of the technical problems and questions of interpretation that arise in the review process. In some instances, regulatory guides may be developed from BTPs after a sufficient experience in their use has accumulated. All ICSB BTPs applicable to the SRP sections in Chapter 7 have been collected in this Appendix for convenience. Other ICSB BTPs applicable to Chapter 8 are pre- sented in SRP Appendix 8-A. When another branch or division is assigned review responsibility for a BTP, that-branch or division is identified parenthetically as part of the BTP designation.
