SUBJECT:
ACKNOWLEDGEMENT OF SEPTEML2R 13, 1996, LETTER, REQUEST i
FOR ADDITIONAL INFORMATION - HADDAM NECK PLANT
Dear Mr. Feigenbaum:
The NRC staff has received your September 13, 1996, response to our August 9, 1996, 10 CFR 50.54 (f) request for additional information.
This letter required you to (1) update and resubmit your basis for continued operation of Haddam Neck, and (2) address the implications of NRC-and Northeast Utilities-identified degraded and non-conforming conditions requiring corrective action to meet the Haddam Neck Plant's design basis.
In your. response, you addressed the second item and stated that the first item could not be addressed until " additional reviews and corrective actions" have been completed.
You committed to not restart Haddam Neck until the actions discussed'in your letter were completed.
You also committed to coordinate with the NRC staff to develop an inspection and submittal schedule for these activities.
Corrective actions requiring licensing actions should be submitted with sufficient time'to support staff review.
Your commitment to not restart the plant until the corrective actions have been completed is an acceptable interim response to the August 9,-1996, letter.
The corrective actions you have outlined are extensive.
I am also aware that you are in the process of updating the Haddam Neck economic analysis.
It is our understanding that you intend to use this updated analysis to aid in making decisions about whether to operate Haddam Neck in the future.
While this reanalysis is being performed, certain tasks have been postponed (including putting new fuel in the spent fuel pool) until comple;; ion of the reanalysis.
l Two more issues regarding recent plant performance should also be i
included and addressed as' corrective actions prior to plant-restart.
These issues were identified during the augmented
~
inspection team (AIT) review of events-occurring between August 22 and September 4, 1996, related to reactor coolant system (RCS) inventory and. cooling capacity (Inspection 50-213/96-80) and 1

during the August 14, 1996, emergency preparedness (EP) exercise (Inspection 50-213/96-07).
Your performance revealed some i
fundamental' weaknesses in plant operations and in emergency response activities.
While some corrective actions have already j
been taken or are planned in response to the recent RCS events and the EP exercise, it is important that you determine the root causes of these weaknesses and take broad corrective actions. to your letter describes Haddam Neck Plant Configuration Management Plan (CMP) restart related activities that provide reasonable assurance that the future operation of Haddam Neck will be conducted in conformance with the
-Commission's regulations.
Since you have concluded there are some similarities in weaknesses between Millstone and Haddam Neck, information on your assessment and. views on the need for an independent corrective action verification program'(ICAVP) at Haddam Neck should be provided as soon as possible after your decision regarding future operation of the facility.
Sincerely,
/s/
