Dear Sir:
Subject:
Response to Inspection Report 50-271/86-15 This letter is written in response to Reference b) which indicates that certain activities were not conducted in full compliance with Nuclear Regulatory Commission requirements. The alleged Severity Level V violation was cited during a routine resident safety inspection conducted by Mr. W.J. Raymond on July 1 - August 4, 1986 at the Vermont Yankee Nuclear Power Station, Vernon, Vermont.
Information is submitted in the following paragraphs in answer to the alleged violation.
VIOLATION Technical Specification 4.4c requires that the boron concentration of l
the liquid poison tank in the Standby Liquid Control System be deter-mined following any addition of water or boron to the tank.
Contrary to the above, following the addition of water to the liquid poison tank on July 8, and on July 15, 1986, no analysis of the tank i
boron concentration was performed until an NRC review of the activi-l ties identified the deficiencies.
l This is a Severity Level V Violation (Supplement I.E.)
Pursuant to the provisions of 10 CFR 2.201, Vermont Yankee Nuclear Power Corporation of Vernon, Vermont, is hereby required to submit to this office within 30 days of the date of the letter transmitting this Notice, a writ-ten statement of explanation in reply including:

Where good cause is shown, considerations will be given to extend your response time.
RESPONSE
At the time of this violation, Vermont Yankee did not have any administra-tive controls in place which would set limits on the time available to obtain the subject Standby Liquid Control System sample after addition of water or boron to the liquid poison tank. Up to the time of this occurrence, Vermont Yankee relied upon supervisory review and follow-up of subordinate actions.
While we believe these interdepartmental reviews would have identified the potentially missed surveillances had Vermont Yankee not been sooner informed by the NRC Resident Inspector, plant review of the incidents identified correctable communication and procedural wea* ness which would preclude further incidents of 4
this type.
The following corrective actions were taken by the Operations Supervisor:
1 1)
The Shift Supervisor was instructed to log all additions to the SLC tank and sample results in the Control Room log book.
2)
The Shift Engineer was instructed to follow up the sampling process through a " feedback" note form.
3)
An administrative limit was set at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for the completion of SLC sample results following any addition to the tank.
4)
An operator aid tag was hung on the domineralized water addition valve to the SLC storage tank which reminds the operator to inform the Shift Supervisor when the valve is opened.
5)
These actions have already been administratively implemented and the necessary procedure changes have been initiated to formalize them.
These procedure changes will be implemented by November 1, 1986.
We trust that this information is deemed to be satisfactory; however, should you have any questions regarding this matter, please contact me.
Very truly yours, 9
