REQUIREMENT 3 Applicants shall describe their program plen, which is to begin during construction and follow into operation, for integrating and expanding current efforts to improve plant procedures. The scope of the program shall include
. emergency procedures, reliability analysis, human f actors engineering, crisis
. management end operator training.
Applicants shall also insure that their program will be coordinated, to the eX ent possible, with INPO and other t
Ir.dustry group efforts. Applicants will submit, prior to the issuance of construction permits, a general discession of how the requirements will be met.
Sufficient detail shall be presented to p'rovide reasonable assurance that the requirements will be implemented properly prior to the issuance of operating licenses.
APPLICATION TO CRBRP:
This requirement is applicable to CRBRP.
IMPLEMENTATION:
CRBRP's program plan to develop plant procedures requires the operator, TVA, to write detailed operating procedures using as a guide procedure outlines developed by designers.
The CRBRP design organizations have the responsibility to assure that the design properly considers all aspects affecting safe operability of the plant.
In preparing these procedure outlines, the most recent recommendations on upgrading procedures are beir.g
('
considered.
When TVA prepares detailed plant procedures from'these outlines 1he most recent industry recommendations on procedure development will be considered.
TVA, as a member of INPO, will use this relationship to maintain an awareness of the ' state-of-the-art' in procedure upgrading and development.
As a followup of "TMI Lessons Learned" an extensive review and update of the CRBRP control room procedure outlines were made. This was accomplished by having a multidisciplinary review team ' walk through' the operating procedere outlines and then upgrade the procedure outlines to reflect the experience gained.
The scope of this activity included both normal operating procedures and emergency procedures.
Reliability analysis and human f actors engineering was a major contribution to this review.
The CRBRP Probabilistic Risk Assessment (PRA) Program will also be utilized to assess procedures and operator interaction. Appendix J, Program Plan for the CRBRP PPA, paragraphs 2.6.1 and 2.6.3 provide additional information on the utilization of Operator Action Event Trees to investigate the role of the plant operation staff in important accident sequences and additional PRA applications to improve understanding of the plant. These PRA applications utilize best estimate analyses.
Further, the Project.will also evaluate plant safety functions to ensure adequate procedures for events with failure combinations not specifically addressed through the PRA effort.
