U. S. Nuclear Regulatory Commission Attention: Document Control Desk Washington, DC 20555 Haddam Neck Plant i
NRC Reauest For Information Pursuant To 10CFR50.54m i
in a letter dated October 9,1996,W the NRC requested that the Connecticut Yankee Atomic Power Company (CYAPCO) provide information on the Configuration Management Project (CMP) at the Haddam Neck Plant (HNP) within 120 days of the receipt of the letter.
The purpose of this letter is to provide CYAPCO's interim response.
Since the receipt of the NRC letter, CYAPCO submitted a letter dated December 5,1996,(2) that informed the NRC that the Board of Directors of CYAPCO had decided to permanently cease operations at the HNP and that the fuel had been permanently removed from the reactor.
Due to this change in the plant status, CYAPCO is in the process of defining the plant ll censing and design bases and modifying the CMP activities for the defueled condition.

U. S. Nucl cr Regulatory Commission B16187/Page 2 Prior to the December 5,1996 letter, CYAPCO had provided the NRC with a description and a status of the CMP effort in letters dated May 30,1996,W June 28,1996W and September 13,1996.*
In addition, on December 4,1996, the Haddam Neck Enforcement Conference was held at the Millstone Site Training Center.
At this Enforcement Conference the common causes for the apparent violations stemming from recent inspections on design and licensing bays issues were discussed.
CYAPCO provided the NRC with the corrective actions for each apparent violation as well as the corrective actons for the common cause, programmatic and organizational issues. In a letter dated December 20,1996,* the NRC docketed this information.
4 This letter is an interim response to the NRC request of October 9,1996. CYAPCO has taken the following actions to assure fuel safety while the actions described in this letter are taken, in a letter dated October 23,1996,W CYAPCO discussed what corrective actions were undertaken prior to defueling the reactor.
These corrective actions continue to be implemented. The HNP Normal, Abnormal and Emergency Procedures were reviewed to assure that the concerns of spent fuel storage are adequately addressed. The service water system, which provides cooling to the spent fuel pool heat exchangers, underwent a through inservice inspection to verify the piping integrity during normal opercting and seismic conditions, in addition, the NRC recently reviewed and approved the configuration of the spent fuel building by the issuance of spent fuel pool rerack License Amendment No.188.W Finally, as discussed in NRC Inspection Report 50-213/96-13,* the NRC reviewed CYAPCO's defueling activities.

and verify that they are being implemented appropriately and document those that are i
not applicable to the' defueled condition. In addition, this activity will provide assurance that the appropriate program checks and balances exist to ensure future commitments i
are implemented. The area is divided into the following two work activities:
1.
Commitments will be identified from correspondence to and from the NRC and placed into a database. _ The correspondence-includes LERs, i
docketed letters by CYAPCO, and letters from the NRC to CYAPCO. The commitments are being characterized in the database by source document, date, system, program and other attributes to assist in the determination of applicability in the defueled condition, the verification of present implementation and/or to assure continuing implementation.
2.
The commitments applicable to the defueled condition that are of an ongoing nature, will be verified.to be implemented by reviews of design documentation, and plant procedures, programs or processes. The future implementation of these commitments is assured by recording the commitments in the database and by identifying procedure steps to be protected at the next revision of the implementing procedures, as required.
The licensing commitment activities will be completed by the end of the second quarter of 1997.

Oversight The Nuclear Safety and Oversight (NSO) organization will monitor implementation of activities related to decommissioning.
Decommissioning will not occur until NSO concludes that the scope and quality of these efforts is sufficient to allow disassembly.
NSO will develop a broad-based assessment plan to determine how activities will be reviewed, the scope of the reviews, and the schedule. The scope of these reviews will focus on the integration of hardware, design bases, and programmatic corrective 4
- actions, a
Specifically, NSO will perform an assessment of the scope of the decommissioning effort to confirm that the initiatives planned will provide reasonable assurance that the plant will be decommissioned in accordance with its defueled condition licensing and design bases.
Their assessment will also consider whether the safety significant degraded and non-conforming conditions and programmatic weaknesses have been resolved and whether there are provisions to maintain the defueled condition licensing and design bases during the decommissioning of the facility.
