Document Control Desk
References:
a) Facility Operating License NPF-56, Docket No. 50-443 b) USNRC Letter dated April 14, 1989, T. E. Murley to E. A. Brown
Subject:
TMI Action Plan Status Gentlemen:
Reference (b) requested the status of implementation of TMI Action Plan items at Seabrook Station. The enclosure from Reference (b) has been marked up per your guidelines to provide the status of each of the listed TMI Action Plan items and is provided as Enclosure 1. provides the requested short notes on each TMI action Plan item where additional information is warranted.
It should be noted that TMI Action Plan item II.K.1.17, "IE Bulletins - Trip per low-level Bistables' was omitted from your list and has been entered on Page 4 of Enclosure 1.
I have reviewed the TMI Action Plan Status and believe it to be correct to the best of my knowledge.
Should you require additional information on this matter, please contact Mr. James M. Peschel at (603) 474-9521, extension 3772.
Very truly yours,

. to NYN-89040 Explanation of Notes on Enclosure 1
- 1) TMI Action Plan Item I.D.1 - Control Room Design Reviews New Hampshire Yankee has committed per SEN-1182 dated August 22, 1986, to provide a final evaluation of the control room environment addressing parameters that will be available during power operation, such as temperature, humidity, airflow, and acoustic noise, to the NRC Staff for confirmatory review after commercial operation is achieved.
l
- 2) TMI Action Plan Item I.D.2.3 - Plant-Safety Parameter Display Console -
Fully Implemented The implementation for this iter is being pursued according to a schedule developed as a result of the Atomic Safety and Licensing Board's March, 1987, Partial Initial Decision as it relates to the Safety Parameter Display System (SPDS).
System availability calculations and a load test will be performed and the results reported to the NRC Staff. These are the last items in the SPDS schedule and will utilize data to be collected durirg the first operating cycle with action currently scheduled to be completed by February 15, 1991.
- 3) TMI Action Plan Item II.B.3.4 - Post Accident Sampling - Plant Modifications Testing of the Post Accident Sampling System is required to verify that it will perform its intended function.
System activity is required to verify operability, therefore this action is scheduled to be performed after low power testing and prior to issuance of a full power license.
- 4) TMI Action Plan Item II.D.1 - Relief and Safety Valve Test Requirements New Hampshire Yankee submitted responses to requests for additional information per NYN-87138 dated November 23, 1987. This item is considered to be completed.
- 5) TMI Action Plan Item II.F.1.2.B - Accident-Monitoring Iodine / Particulate Sampling New Hampshire Yankee submitted a report per NYN-89032 dated March 27, 1989, describing the status of this item.
Operability of the iodine / particulate sampling system has been demonstrated in the particulate and radiciodine transmission modeling and analyses which were performed by Science Applications International Corporation (SAI).
The results of this effort, which indicate acceptable transmission factors for gaseous effluent sample lines, are documented in a report which will be submitted for NRC Staff review by May 30, 1989.
s The modeling and analyses indicated a need to improve the transmission factor for the Wide Range Gas Monitor (WRGM) high range sample line.
Installation of a design change will be complete by September 30, 1989.
- 6) TMI Action Plan Item III.A.2.1 - Upgrade Preparedness - Upgrade Emergency Plans to Appendix E 10 CFR 50.
Two individual actions are required to complete the implementation of this TMI Action Plan Item. The two actions, implementation of a Public Alert and Notification System in Massachusetts and final distribution of public brochures, are presently awaiting the completion of the Atomic Safety and Licensing Board (ASLB) Emergency Preparedness Hearings. The Commissioners have indicated that they expect the ASLB to issue a Final Initial Decision by September 30, 1989. New Hampshire Yankee will take the appropriate action to complete the actions prior to the issuance of the full power license.
- 7) TMI Action Plan Item III.D.3.4.2 - Control Room Habitability - Schedule Modifications TMI Action Plan Item III.D.3.4.3 - Control Room Habitability - Implement Modifications Tia action required to implement this item has been completed for power levels up through SZ rated thermal power. A design change approved by the NRC Staff in a letter dated August 24, 1988, will be completed by September 30, 1989, as previously stated in NHY letter NYN-89032 dated March 27, 1989.
