letter, USNRC t VYNPC, dated 5/2/84, and Inspection Report No. 84-0) Appendix A (Notice of Violation)
Dear Sir:
Subject:
Response to Inspection Report 84-07 This letter is written in response to Reference b), which indicates that one of our activities was not conducted in full compliance with Nuclear Regulatory Commission requirements.
This alleged Level V violation was iden-tified as a result of an inspection conducted by your Mr. Kottan during the period of March 26-29, 1984 Information is submitted as follows in answer to the alleged violation con-tained in the Appendix to your letter.
Item:
Appendix "A" to License No. DPR-28, Technical Specifications (TS),
Section 3.7.B.2, requires that in-place cold D0P and halogenated hydrocarbon tests at design flows be performed on the Standby Gas Treatment system. Also, Section 3.7.B.2 of the TS requires that system fans be shown to operate within _+ 10% of design flow.
Contrary to the above requirement, the data for the air flow capacity test of the Standby Gas Treatment System Train B performed on January 10, 1984 indicated a flow of 1263 CFM which is not within + 10% of'the design flow of 1500 CFM. Therefore, the in-place cold 00P and haloge-nated hydrocarbon tests of January 10, 1984 were not performed at the design flow as required.
This is a Severity Level V violation (Supplement I).

Response
As stated in the finding, air flow capacity testing of the Standby Gas Treatment System (B Train) was performed on January 10, 1984 and the results indicated a flow rate of 1263 CFM which is not within the Technical Specification requirement of 1500 CFM + 10%. As a result of the low flow, adjustments were made to t;ie system's Tan damper and a retest was performed with a satisfactory flow rate of 1538 CFM. This rate was further substan-tiated by a control room indication of >1500 CFM.
Due to an apparent transcription error, the raw data from the first test wa.; entered onto the form for the retest.
Consequently, the 1538 CFM figure, altanugh correct, lacked the proper supporting data.
On March 30, 1984, in-place cold 00P and halogenated hydrocarbon tests were conducted the "B" train with satisfactory air flow capacity and all required data was properly recorded.
As a measure to prevent recurrence, forms used to document tests of this nature will be reviewed by supervisory personnel.
This change, currently implemented administratively, will be added to the applicable procedures as they become due for biennial review.
We trust the above information is satisfactory; h.owever, should you have questions or dr31re additional information, please do not hesitate to contact us.
Very truly yours, VERMONT YANKEE NUCLEAR POWER CORPORATION M
