BIG ROCK POINT NUCLEAR PLANT EMERGENCY OPERATION PROCEDURE VALIDATION PROCEDURE
- 1. 0.
PURPOSE AND SCOPE To guide the administrative process used in validation of the Emergency Operating Procedures (EOPs). Upon completion of the E0P validation program process, a thorough evaluation of the E0Ps for usability and operational correctness will have been conducted.
Deviations in the E0Ps will have been identified, evaluated, and resolved.
This plan provides guidance for E0P validation utilizing the table-top and walk-through methods. It only applies to E0P validation prior to implementation of the E0Ps.

E BIG ROCK POINT NUCLEAR PLANT EMERGENCY OPERATION PROCEDURE VALIDATION PROCEDURE 4.6 Table-Top Validation - Method of validation whereby personnel explain and/or discuss procedure action steps for an observer /
reviewer in response to a scenario or as part of an actual industry operating experience review.
4.7 Walk-Through Validation - Method of validation whereby control room operators conduct a step-by-step ersetment of their actions during a scenario for an observer / review team without carrying out the actual control functions. May also include use of a simulator with manipulation of controls and observation of instrumentation.

Reviewing and approving E0P validation assessments and any discrepancies / resolutions forwarded to him by the E0P Validation and Verification Coordinator.
B.
Resolving any discrepancies which can not be resolved by the E0P Validation and Verification Coordinator.
C.
Ensuring that the E0Ps have received the proper technical, administrative and safety evaluations.
D.

r BIG ROCK POINT NUCLEAR PLANT EMERGENCY OPERATION PROCEDURE VALIDATION PROCEDURE 6.0 PROCESS FOR E0P VALIDATION The E0P validation process can be described by the three phases of preparation, assessment, and resolution.
6.1 Preparation - The validation process will use the applicable evaluation criteria presented in Table 1, and the scenario to be used will be recorded on the appropriate scenario form.
(Table-Top / Walk-Through Scenario Form, Attachment 2 or similar form).
The designated observer / reviewer will be responsible for the following:
A.
Using and completing the E0P Validation Form (Attachment 1) or similar form.
B.
Reviewing the scope of the validation designated by the operations supervisor or his representative.
C.
Developing or modifying scenarios to support the scope of validating and filling out the Table-Top / Walk-Through Scenario Form (Attachment 2) or similar form.
D.
Modifying / selecting the developed evaluation criteria to support the scope of validation.
E.
Selecting operators that are representative of the training level expected of all the operators.
F.
Selecting the needed resources.
6.2 Assessment - The designated observer / reviewer will perform the following duties:
A.
Brief the operator on the scope of validation and how the assessment will be conducted.
B.
Follow the developed or modified scenario by first giving the plant initial conditions and then give the changing plant parameters as talking or walking through the procedures.
C.
Stop the talk-through or walk-through assessment for discussion of any identified discrepancies.
D.
Conduct a debriefing with the operators as soon as possible after each walk-through assessment, using the following sequence:
brief the participants on the purpose and objectives for debriefing 3
Rev 0 NL01-RRF12A-PGP
BIG ROCK POINT NUCLEAR PLANT EMERGENCY OPERATION PROCEDURE VALIDATION PROCEDURE have operators present problems and discrepancies which they had identified during assessment have operators provide possible reasons for problems present other problems and discrepancies identified during assessment have operators describe possible reasons for the other problems i
summarize the findings of the debriefing for the operators.
E.
Record discrepancies and comments on the Discrepancy Sheet (Attachment 3) or similar form.
6.3 Resolution - The designated observer / reviewer will* perform the following duties:
A.
Review comments and discrepancies.
B.
Describe any proposed resolutions on the Discrepancy Sheet (Attachment 3) or similar form.
C.
Submit the validation package to the E0P Validation and Verification Coordinator.
The E0P Validation and Verification Coordinator will perform the following duties:
A.
Review proposed resolutions with appropriate staff.
B.
Select resolutions for incorporation in the E0Ps.
i C.
Forward the revised E0Ps to the E0P Project Manager for i
review.
7.0 DOCUMENTATION The documented items needed to provide a history of the validation program are the completed Validation Form. Scenario Form (s) if needed, and Discrepancy Sheet (s) if needed. These items will be maintained as a validation package in the Document i
Control Center (DCC) in accordance with Big Rock Manual, Volume i
1, Chapter 11.
l j
All E0P validation documentation which has been approved by the PRC is to be submitted to DCC by the E0P Project Manager.
