gnificant deviations from the mitigative strategy should be described. Furthermore, applicants using generic guidelines need not submit the detailed action steps. The process for developing the action steps from the generic guidelines should be described. Applicants not using generic guidelines should submit, as a part of the P-STGs, the action steps necessary to mitigate transients and accidents, 13.5.2.1-14 Revision 2 - March 2007 as well as supporting technical analysis and bases. The P-STGs should have an orientation that allows mitigation without event diagnosis. In either case, the applicant should submit a description of how operator information and control needs were derived and used to specify instrumentation and control requirements. The guidance presented below identifies elements reviewers should consider in determining the acceptability of P-STGs. B. General Technical Objectives. The purpose of the review of the technical guidelines submittal is to determine that the following general objectives are adequately addressed. Specific evaluation elements are identified in Subsections 3.3 and 3.4. i. The EOPs will be based on acceptable technical guidelines derived from approved analyses of transients and accidents as described in NUREG-0660, items I.C.1 and I.C.9, as clarified by item I.C.1 in NUREG-0737 and Supplement 1 to NUREG-0737. The P-STGs, the generic guidelines (if referenced), and supporting documentation provide EOP writers with all the technical information necessary for preparing EOPs which direct operators' actions to mitigate the consequences of transients and accidents without a need to first diagnose an event to maintain the plant in a safe condition (function orientation). Part of the acceptability of the P-STGs is that the P-STGs are validated by the applicant using methods acceptable to the reviewer (see NUREG-0899, Sections 2.6 and 4.2). ii. The PGP describes an adequate method to identify information and control needs and to provide a
