information notices). E. Policy issues raised for the standard designs. F. New design features (such as communications between various portions of the digital system or other systems). All of the new features may not need Tier 1 treatment. G. Insights or key assumptions identified through the PRA. H. GSI resolutions that have resulted in design/operational features. I. Post-TMI requirements (e.g.,post-accident monitoring). 2Refer to RG 1.206, Section C.I.7, Appendix 7B for additional discussion on conformance with IEEE Standard 603. 14.3-38 March 2007 II. ITAAC Entries (for the above equipment) The I&C ITAAC should be developed to address the following considerations: A. Compliance with 10 CFR 50.55a(h), “Criteria for Protection Systems for Nuclear Generating Stations,” and IEEE Standard 603-1991 (and the Correction Sheet Dated January 30, 1995)2. The following sections correspond to sections in the IEEE Standard. • Section 4.1 Identification of the design-basis events. The ITAAC should verify the inclusion of the initial conditions and allowable limits of plant conditions for each DBE. • Section 4.4 Identification of monitored variables. The ITAAC should verify the analytical limit associated with each variable, the ranges (normal, abnormal, and accident conditions), and the rates of change for these variables to be accommodated until proper completion of the protective action is ensured. • Section 4.5 Minimum criteria for manual initiation and control of protective actions subsequent to initiation. The ITAAC should verify the points in time and the plant conditions during which manual control is allowed, the justification for permitting initiation or subsequent control solely by manual means, the range of environmental conditions imposed upon the operator during normal, abnormal, and accident circumstances throughout which the manual operation is performed, and the variables that should be displayed for the operator to use in taking manual action. •
