l Final Response The objective of CYAPCO's 10CFR50.54(f) program is to provide assurance that the HNP will be decommissioned in accordance with the terms and conditions of the operating license, NRC regulations and the UFSAR. Management and CY Oversight has reviewed and verified

. the following areas to ensure that the objective is met:

.1. Licensing Commitments

2. Revised Accident Analyses-
3. Updated Final Safety Analysis Report (UFSAR)
4. Spent Fuel Storage Licensing and Design Bases Reviews CY Oversight has also provided for independent review of these areas to verify effective implementation. The scope and status for each area are discussed in the following:

1.

Licensina Commitments Licensing commitment activities are divided into the following two work activities:

a.

Commitments have been identified from correspondence to and from the NRC and placed into a database. The correspondence includes LERs, docketed letters by CYAPCO, and fetters from the NRC to CYAPCO. The commitments have been characterized in the database by source document, date, system, program and other attributes to assist in the determination of applicability in the defueled condition. Over 13,500 commitments have been identified.

This task has been completed.

CYAPCO Letter CY-97-125, from R. A. Mellor, to the U. S. Nuclear Regulatory Commission, "NRC Request For information Pursuant To 10CFR50.54(f)," dated December 24,1997.

U. S. Nucl:ar R::gulatory Commission CY-98-153/ Attachment 1/Page 2 b.

Approximately 2,080 of the over 13,500 commitments were initially identified as hpplicable to the defueled condition. Further review of these 2,080 commitments demonstrated that the majority had been appropriately implemented and were completed or are no longer applicable to the present plant configuration. However, the review indicated that approximately two hundred eighteen (218) commitments remain as either active commitments or commitments which require action. Eighty-eight (88) commitments are being actively implemented by design documentation,

{

plant procedures, programs or processes. Approximately one hundred thirty (130) commitments were identified as requiring action to implement the commitment.

None of these 130 commitments are considered to be overdue. In certain cases, the required action may involve a procedure revision with an associated footnote. A procedure or procedure step is required to be footnoted when the procedure serves to implement a commitment. The action to footnote or revise procedures is being j

tracked under the plant action tracking system. The commitment tracking system i

reflects the status of those commitments which require action to be taken. Future commitments are identified, managed and dispositioned under Licensing Department Instruction LDI 2.01

i This review has been completed.

2.

Revised Accident Analvses The UFSAR Chapter 15 accident analyses activities verified important plant parameters. The area was divided into the following work activities:

a.

Key parameters associated with the redefined accident analyses assumptions and inputs, and the structures, systems, components and programs required to support tile safe storage of spent fuel have been identified and documented.

b.

The key parameters were verified by reviewing each parameter against associated calculations, UFSAR sections, surveillance procedures, setpoint control documents and other documentation with respect to the safe storage of spent fuel.

The Chapter 15 accident analyses have been revised for the defueled configuration and have been included in the January 26,1998* revision to the UFSAR. As decommissioning progresses, the accident analyses are reviewed and revised, as appropriate for the changing plant conditions.

Uodated Final Safety Analvsis Reoort (UFSAR)

The UFSAR has been reviewed to identify and correct deficiencies applicable to structures, systems, components and programs required to support the defueled condition, licensing and design bases and decommissioning activities. The resulting revision reflects those systems recategorized for the defueled condition to date, as well as correction of known deficiencies associated with the defueled condition. The recategorization process is a

. continuing process and the UFSAR will be periodically updated to reflect changes.

The Licensing Commitments,' UFSAR Chapter 15 accident analyses, Defueled Technical Specifications, and Defueled Condition Licensing and Design Bases Reviews have been compared to the UFSAR. The changes identified were evaluated using the 10CFR50.59 i

safety evaluation process.

i A complete' revision to the UFSAR was docketed on January 26,1998.

4.

Soent Fuel Storage Licensing And Design Bases Reviews For structures, systems, components and programs required to support the safe storage of spent fuel, the licensing and design bases have been identified and verified. As part of this I

review, new calculations have been developed for the spent fuel pool heatup rates and for

)

the UFSAR Chapter 15 accident analyses. The licensing basis identification included reviews of correspondence commitments as well as licensing basis documents such as the UFSAR, Technical Specifications, Technical Requirements Manual, Safety Evaluation Reports, and Facility Description and Safety Analysis. The design basis identification included reviews of design changes, Design Basis Document Packages, calculations, drawings, specifications, vendor information, etc. The verification of plant configuration with the license and design bases was performed through reviews of operating, maintenance, and surveillance procedures and walkdowns. This effort was focused on maintaining the integrity i

of the spent fuel in the spent fuel pool. The following approach was established and completed:

Review the basic calculations for the hydraulics, structures, electrical distribution and instrumentation needed for the safe storage of spent fuel.

Review docketed correspondence to establish the licensing and design basis for the safe storage of spent fuel.

. - Reconcile the design basis with the UFSAR, operating, maintenance and surveillance procedures, and Technical Specifications.

Perform walkdowns to verify expected configurations.

Document the licensing and design basis for the safe storage of spent fuel.

Changes and. Revisions to Licensing Basis and Design Basis (LB/DB) Document. Other licensing and design basis documents such as the UFSAR, Technical Specifications, Technical Requirements Manual are also controlled by existing station procedures.

The licensing and design bases reviews and documentatior; have been completed. An independent review and a separate third-party review, of the licensing and design bases documentation, was conducted. Results to date have shown an effective configuration process for maintenance of the licensing and design basis.

Current CY Oversight Surveillance Activity CYAPCO responded to a Level IV violation, involving incomplete channel calibration of the stack flow monitor, in a September 21,1998 Notice of Violation response letter. One of the W

corrective actions being taken as a result of this violation is a verification of all portions of License Amendment 125 (i.e., conversion to Standard Technical Specification format and definitions) that remain in effect as amended by License Amendment 193 (i.e., defueled Technical Specifications). The Oversight organization is verifying that for each Technical Specification surveillance requirement, the existing procedure (s) adequately perform (s) the activity required by the Technical Specifications.

Actions such as this CY Oversight surveillance are an example of the ongoing efforts to ensure that design basis requirements are translated into plant procedarbs. As

' decommissioning progresses, any deviations from the licensing and design basis are reported through our Adverse Condition Reporting (ACR) Program.
