Content:
review performed for an operating license (OL)'application is based upon detailed design information that confirms that the final design conforms to the design bases and applicable criteria. The depth of the review for an OL'application should be sufficient to conclude that the requirements of the Commission regulations have been satisfied. The depth of the review for the balance of the criteria should be sufficient to conclude that the systems conform with the guidelines to the extent to support the findings of conformance to the regulations. The review includes the process to sensor coupling, sensors, initiating circuitry, logic bypasses, interlocks, redundancy features, and actuated devices of those systems which provide the necessary instrumentation and control functions to achieve and maintain safe shutdown. Typical systems required for safe shutdown are: Auxiliary Feedwater Systems Residual Heat Removal Systems Boric Acid Transfer Systems Typical essential auxiliary supporting (EAS) systems are: Electric Power Systems Diesel Generator Fuel Storage and Transfer. Systems Instrument Air Systems Heating, Ventilation, and Air Conditioning (HVAC) Systems for Areas Containing Systems Required for Safe Shutdown Essential Service Water and Component Cooling Water Systems The scope of the ICSB review of Section 7.4 of an SAR includes: 1. The descriptive information, functional control diagrams, piping and instrument diagrams (CP), and electrical schematics (OL) pertaining to safe shutdown systems. 2. The acceptance criteria, guidelines, and design bases for the design of the systems required for safe shutdown (CP). 3. The applicant's analysis of conformance to the acceptance criteria, guidelines, and design bases for the systems required for safe shutdown (OL). In addition, the ICSB will coordinate with branches that interface with the overall review of systems required for safe.shutdown including the following: The -Power Systems Branch (PSB) evaluates the redundancy
