is 87 commitment is should be stated in the applicants' SAR. 88 2. The applicant has met the requirements of GDC 5, "Sharing of Structures, Systems, and Components" with Rrespect to the Ccapability of Sshared Ssystems and Ccomponents,"89 important to safety to perform required safety functions. We have reviewed the interconnections from the MSSS of each unit to __________. The interconnections are designed so that the capability to mitigate the consequences of an accident in either unit and achieve safe shutdown in that unit is retained without reducing the capability of the other unit to achieve safe shutdown. or Each unit of the __________ plant has its own MSSS with no interconnections between the safety-related and/or nonsafety-related portions. 3. The applicant has met the requirements of GDC 34, "Residual Heat Removal," with respect to the system function of transferring residual and sensible heat from the reactor system in PWR plants. The MSSS is capable of providing heat sink capacity and pressure relief capability and supplying steam to the steam driven safety-related pumps necessary for safe shutdown. The MSSS is also designed to include the capability to operate the atmospheric dump pump valves remotely from the control room following a 90 safe shutdown earthquake coincident with the loss of offsite power so that a cold 10.3-15 DRAFT Rev. 4 - April 1996 shutdown can be achieved with dependence upon safety-grade components only. This meets the positions in Branch Technical Position RSB 5-1, "Design Requirements of the Residual Heat Removal System," and in Issue 1 of NUREG-0138. 91 4. The applicant has met the requirements of 10 CFR 50.63 with respect to MSSS capacity and capability for station blackout. Acceptance is based on meeting the guidance of Regulatory Guide 1.155, Positions C.3.2, C.3.3, and C.3.5.92 For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report
