precluded as a result of the TBS failure. 2. The applicant has met the requirements of GDC 34 "Residual Heat Removal" with respect to the-ability to use the turbine bypass system for shutting down the plant during normal operations. The turbine bypass system is designed such that sufficient steam can be bypassed to the main condenser so that the plant can be shutdown during normal operations without using the turbine generator. The staff concludes that the design of the turbine bypass system con- forms to all applicable GDC's, staff positions and industry standards and is therefore acceptable. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations.
