Subject:
Docket No 50-482:
Updated Safety Analysis Report (USAR) Review Conmitment Gentlemen:
As stated in previous correspondence, WCNOC remains committed tc maintaining Wolf Creek's Design Bases (DB) as defined in 10 CFR 50.2 and the Licensing Bases (LB).
This letter reaffirms WCNOC's commitment and provides additional detail of WCNOC's current plan to conduct a formal review of the USAR.
As our review progresses, we may make adjustments to the review scope and schedule.
Adjustments to our scheduler commitment to complete the review by April 30, 1998, will be fq-mally communicated to you.
The objectives of the Wolf Creek USAR Review are to:
Provide reasonable assurance that any previously unknown, USAR-related, safety or regulatory significant concerns which could affect the on-going operations are identified (i.e.,
potential unreviewed safety questions, or conflicts involving the Technical Specifications); and Provide reasonable assurance that the USAR is accurate and complete (i.e.,
consistent with the as-built, as-operated and as-licensed plant).
The currently planned USAR Review scope employs a literal read and sampling technique to achieve the above objectives for both Design Bases and Administrative Control related USAR sections.
The USAR Review combines both informal day-to-day reviews based on n.anagement emphasis on USAR fidelity and more formal programs.
References 2-7 provide WCNOC's DB/LB commitments which may involve or impact the USAR.
These commitments include the performance of
/
system functional assessments and conversion to Improved Standard Technical G
Specifications.
Non-conformances identified through these reviews will be dicpusitioned through the corrective action program.

t The focus of the literal read is to identif y obvious differences between the USAR description and the existing plant design, as-built configuration, operating practices, other licensing documents and administrative and technical controls Knowledgeable individuals will complete these reviews which will encompass the entire USAR.
This literal read will also contribute i
to the selection of items for sampling that will be used to confirm that there j
is a reasonable assurance that the USAR accurately reflects plant design, current plant configuration, procedures and programs.
Sampling will include such techniques as comparison of USAR statements with regulatory correspondence, design documents and aaministratise centrols, plant walkdown l
of selected drawings, plant operating procedures and evaluation of historical and ongoing USAR issues.
Based on the results 01 both the literal read and the sampling validation, the scope and extent of additional review will be evaluated, documented and implemented as necessary.
Therefore, the scope and thoroughness of this review will be consistent with a level of detail that provides reasonable assurance that the fundamental plant design, as-built condition, and operat ing practices are properly described in the USAR.
It is not intended to validate every paramcter te.g.,
an instrument setpoint, valve stroke time, analydis input, etc.),
statement, figure, and table in the USAR.
However, if identified discrepancies indicate that there may be generic implications regarding the extent or severity of related j
discrepancies, the scope will be adjusted to ensure that comprehensive corrective actions are inplemented to identify and correct similar
]
discrepancies.
The W'.'NOC corrective action program will be implemented to address discrepancies. The corrective actica program includes administrotave features that require the impact of the discrepancy on operations be promptly evaluated identified to the Shift Supervisor and that repvr tebili ty is considered.
It also requires that root cause evaluation be performed for those dis:,repancies that are considered significant by WCNOC management personne WCNOC is in the process of realigning several on-going design basis (i.e.,
System Functional Assessments) and License Basis (Improved Standard Technical Specification Conversion) programs.
Our goal is to create one DB/LB station-wide program. A description of this station-wide program and any revisions to our prior regulatory commitments will be provided to you by the end of June, 1997.
This letter is being submitted to satisfy the October 18, 1996, Policy Statement condition for establishing a program with goals, scope and schedule l
to ensure compliance with the USAR in order to satisfy the conditions of l
If further informatien is required to satisfy the enforcement discretion criteria, please contatt me at (31C) 364-8831, l

Flannigan at extension 4500.
