(a) License No. DPR-28 (Docket No. 50-271)
(b) US AC Letter to VYNPC, dated November 6, 1978 (Inspection Report 50-271/78-22)
Dear Sir:
Subject:
Response to I&E Inspection Report No. 78-22 This letter is written in response to Reference (b) which indicates that one of our activities was not conducted in full cornliance with Nuclear Regulatory requirements. This alleged infraction was noted during an inspection conducted on October 3-6, 1978, at the Vermont Yankee Nuclear Pow u Station in Vernon, Vermont.
Information is sub-mitted as follows in answer to the alleged infraction contained in the enclosure to your letter:
Item - Technical Specification 6.5.A states in part:
" Detailed written procedures... covering areas listed below shall be prepared and approved. All procedures shall be adhered to."
Refueling operations is an area covered by the above specification. Procedure 0.P. 1101, Revision 7, Fuel Assembly Movement, states that Source Range Monitors (SRM) must be continuously monitored whenever fuel is being moved 1.n the reactor vessel.
(
Contrary to the above, on October 4,1978, fuel bundles N
were inserted into *he reactor vessel while the SRM's were 9
not being continuously monitored.
Response - It has never been the intent at Vermont Ysatee, or a requirement of our Technical Specificatione, to station an operator whose complete attention is freused continuously on a single parameter. We prefer to have instrumentatien continuously monitoring the n4cessary parameters and operator.
overseeing the instrumentation.
United States Nuclear Regulatory Commission November 28, 1978 Att: Office of Inspection and Enforcement Page 2 In response to the specific alleged item of noncompliance, we feel we did continuously monitor the Source Range Monitors, in that we:
1) continuously recorded SRM level on the strip chart recorders; and 2) manually logged SRM level after each in-core move. We believe this practice to be appropriate and consistent with similar requirements identified by station technical specifications, which include the following:
1.
" Radioactive liquid effluents released from the facility shall b e continuously monitored"............................ 4. 8. A.1 2.
"When the continuous conductivity monitors indicate abnormal c onduc tivi ty"...................................... 4. 6. B. 3. a 3.
" Radioactive gases release' from the plant stack shall be con-tinuously monitor ed"............................... 4. 6. C.1. a 4.
" Radioactive gases released from the air ejector shall be con-tinuously monitor ed"............................... 4. 6. C.1. f 5.
" Free residual chlorine concentration shall be continuously monitored"........................................ Appendix B, 2.0.B.1 Based on the above, we do not believe.iny procedural requirement was violated and therefore no corrective action is dee=ed necessary.
We trust this information will be satisfactory.
Should additional information be required, please feel free to contact us.
Very truly yours, VERMONT YANKEE NUCLEAR POWER CORPORATION u-
