REVIEW RESPONSIBILITIES Primary - AuxiliaryPlant Systems Branch (ASB)(SPLB) 1 2 Secondary - None I. AREAS OF REVIEW At the construction permit (CP) stage of review, ASBSPLB reviews the information in the 3 applicant's safety analysis report (SAR) in the specific areas that follow. At the operating license (OL) stage, ASBthe SPLB review consists of confirming the design accepted at the CP 4 stage. For design certification, SPLB reviews the design in the standard SAR against the acceptance criteria set forth in subsection II below.5 1. The system descriptions for the potable and sanitary water systems (PSWS) are reviewed. The piping and instrumentation drawings (P&IDs) are reviewed at the OL stage. 2. System design criteria to prevent connection to systems having the potential for containing radioactive material are reviewed. 3. The applicant's evaluation of potential radiological contamination, including accidental, and safety implications of sharing (for multi-unit facilities) is to be reviewed and accepted.6 DRAFT Rev. 3 - April 1996 9.2.4-2 II. ACCEPTANCE CRITERIA ASBSPLB accepts the design of the PSWS if the requirements of General Design Criterion 60 7 (GDC 60) are met as it relates to design provisions provided to control the release of liquid 8 effluents containing radioactive material from contaminating the PSWS. Compliance with GDC 60 is established if the following are met: 1. There are no interconnections between the PSWS and systems having the potential for containing radioactive material. 2. The potable water system is protected by an air gap, where necessary. 3. An evaluation of potential radiological contamination, including accidental, and safety implications of sharing (for multi-unit facilities) indicates that the system will not result in contamination beyond acceptable limits.9 Technical Rationale The technical rationale for application of the acceptance criterion for the reviewing the PSWS is discussed in the following paragraphs:10 Compliance
