on as part of its primary review responsibility for SRP Section 10.2.3.10 2. Power Systems Branch (PSB) The Plant Systems Branch (SPLB) reviews the turbine 11 overspeed protection, including overspeed sensing and tripping, as part of its primary review responsibility for SRP Section 10.2. 3. The Mechanical Engineering Branch (MEB) (EMEB) reviews the adequacy of the 12 13 inservice testing program of pumps and valves as part of its primary review responsibility for SRP Section 3.9.6. 4. Equipment Qualification Branch (EQB) The EMEB reviews the seismic qualification of 14 instrumentation and electrical system components and the SPLB reviews the 15 environmental qualification of mechanical and electrical system components as part of its their primary review responsibility for SRP Sections 3.10 and 3.11, respectively. The 16 Instrumentation and Control Systems Branch (HICB), in cooperation with the EMEB and SPLB, reviews seismic and environmental qualification of instrumentation as part of its secondary review branch responsibilities for SRP Sections 3.10 and 3.11.17 5. ASB The SPLB identifies structures, systems, and components to be protected from 18 turbine missiles as part of its primary review responsibility for SRP Section 3.5.2. For those areas of review identified above as being reviewed as part of the primary review 19 responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. sections.20 II. ACCEPTANCE CRITERIA MTEB acceptance criteria are based on the plant design and layout satisfying the requirements of General Design Criterion 4 (Ref. 1), which requires that structures, systems, and components important to safety shall be protected against the effects of missiles that might result from equipment failures, in this case the steam turbine. Consideration of turbine missile protection is relevant for essential systems, i.e.,
