lemented in accordance to the guidelines of RG 1.105. The accuracy and range of indicating instru- mentation should be consistent with the assumptions of the accident analyses. Any exceptions to these requirements will be referred to the appropriate branch for resolution on an individual case basis. 6. The guidelines for instrument sensing lines are provided in RG 1.151. The review should confirm that the environmental monitoring system is designed and implemented in accordance to the guidelines of RG 1.151 7.5-3 Rev. 3 - February 1984 position 5. Meeting this position will assure that safety related instrument sensing lines are protected from the effects of freezing due to extreme cold weather. 7. The safety parameter display system (SPDS), the information systems associated with these emergency response facilities, and nuclear data link are reviewed to confirm that they conform to the guidelines in NUREG-0696, "Functional Criteria for Emergency Response Facilities" (Ref. 5). An important part of the review is the engineering drawing review at the OL stage. The drawing review should confirm that the design and layout meet the applicable criteria listed under subsection II. A site visit should be performed before the evaluation findings are written for an OL. The site visit should include an audit verification that the design and layout criteria reviewed during the drawing review are implemented. An outline of topics for a site visit is provided in Appendix 7-B (Ref. 6) to SRP Chapter 7. In certain instances, it will be the reviewer's judgment that for a specific case under review, emphasis should be placed on specific aspects of the design, while other aspects of the design need not receive the same emphasis and indepth review. Typical reasons for such a nonuniform placement nf emphasis are the introduction of new design features or the utilization in the design of design features previously reviewed and found acceptable. However, in all cases, the review must be
