OFFICE OF NUCLEAR REACTOR REGULATION SECTION 1.8 INTERFACES FOR STANDARD DESIGNS
~
REVIEW RESPONS!BILITIES Primary - All review branches (except Quality Assurance Branch (QAB))
Secondary - None I.
AREAS OF REVIEW The areas of review include all the safety-related interfaces, important to the staff review for safety, that exist between the systems, components and structures within a standard design as they relate to matching systems, components and structures within the remaining unspecf fied portion of the plant design. Also included is the implementation of interface requirements in the design of matching safety-related systems, components and structures. The specific interfaces identified for the nuclear steam supply system (NSSS) and for the balance-of-plant (80P) portions of a nuclear plant design are given in " Interfaces for Standard Designs." Appendix A to Regulatory Guide 1.70.
!!. ACCEPTANCE CRITERIA The acceptance criteria for interfaces, as appropriate, are contained in the sections of the SRP aoplicable to the particular area under review. While these acceptance criteria are not specifically identified as pertinent to interfaces, they nevertheless apply to the interfaces that are encompassed by the review area to which the criteria apply.
!!!. REVIEW PROCEDURES The reviewer in each responsible review branch will select and emphasize material from this review plen, as may be appropriate for a particular case. The particular interfaces to be addraisej in SSARs describing standard NSSS and BOP designs and in SARs describing the entire plant design in support of lisenses are presented in Regulatory Guide 1.70 Appendix A.
l.
Standard designs for the NSSS are reviewed to assure that the applicable safety-related interfaces to, and in several instances assumed for. the matching, but un-specified. BOP site, and utility portions are identified and defined.

2.
Standard designs for the BOP are revie39d to assure that (a) those applicable safety-related interfaces established for the '!$$5 are addressed, (b) those inter-faces assumed by the flSSS are compatible with the 30P design, and (c) the applicable safety-related interfaces to the matching, but unspecified, site, and utility portions are identified and defined, u
3.
Utility applications are reviewed to assure that the applicable safety-related interfaces established for the referenced standard NSSS design alone, or the referenced standard NSSS and BOP designs combined, are addressed.
IV. EVALVATION FINDINGS Each review branch verifies that sufficient interface information has been provided and I
properly implenented, as appropriate, and that the review is adequate to support con-clusions of the following type, to be included in the staff's safety evaluation report:
For standard design reviews:
" Interfaces provide the means for assuring that the standard design and other unspecified portions of the plant design are compatible with regard to the performance of all safety-related systems, components, and structures under all modes of operation and shutdown.
The scope of our review included an evaluation of the interfaces defined by the applicant in accordance with the guidelines given in Regulatory quide 1.70, Appendix A, and the Based applicable criteria for acceptance given in the appropriate sections of the SRP.
on our evaluation, we find the interface information provided in the standard design aoplication acceptable."
For applications referencing standard designs:
" Interfaces established for the standard design are addressed in the referencing applica-tion to demonstrate the compatibility of the standard design with the remaning portions of the plant design regarding the performance of all safety-related systems, components and structures under all modas of operation and shutdown. The scope of our review included an evaluation of the matching safety related systems, components and structures to assure compatibility in accordance with the applicable criteria for acceptance given in the appropriate sections of the SRP, Based on our evaluation, we find that the interfaces have been properly addressed and that compatibility of the standard design f
with the remaining portions of the plant design can be achieved."
