nt following a steam line break. 3. The Mechanical Engineering Branch (MEBEMEB) reviews the effects of blowdown 17 loads, including jet propulsion piping and component supports, as part of its primary review responsibility for SRP Sections 3.6.2 and 3.9.1 through 3.9.3. In addition, MEB 18 EMEB reviews the design bases for safety and relief valves in SRP Section 3.9.3. 4. The Materials and Chemical Engineering Branch (EMCB) reviews the fracture toughness properties of the reactor coolant pressure boundary and reactor vessel as part of its primary review responsibility for SRP Sections 5.2.3 and 5.3.1.19 5. The Containment Systems and Severe Accident Branch (CSBSCSB) evaluates the 20 response of the containment to ruptures of steam lines with regard to the effects of pressure and temperature on the containment functional capabilities as part of its primary review responsibility for SRP Section 6.2.1. CSB SCSB also reviews the analytical methods for deriving nuclear steam supply system (NSSS) mass energy releases exiting 21 a postulated break. The Core Performance Branch (CPB) reviews all the nuclear design aspects, this includes power levels, power distributions, Doppler coefficients, moderator temperature coefficients, reactor kinetics parameters, DNB correlations and control rod worths as part of its primary review responsibility for SRP Sections 4.2, 4.3 and 4.4. 22 6. The ICSB HICB reviewer concentrates on the instrumentation and controls aspects of the sequence described in the SAR to evaluate whether the reactor and plant protection and safeguards controls and instrumentation systems will function as assumed in the safety analysis with regard to automatic actuation, remote sensing, indication, control, and DRAFT Rev. 3 - April 1996 15.1.5-4 interlocks with auxiliary or shared systems. The HICB review includes an evaluation of the instruments and controls required to ensure automatic and manual axillary feedwater system initiation and flow indication in the
