ENCLOSURE RESPONSE - NRC-OIE INSPECTION REPORT NOS. 50-327/85-32 AND 50-328/85-32 DAVID M. VERRELLI'S LETTER TO H. G. PARRIS'
- DA'TED OCTOBER 30, 1985 Violation 50-327/85-32-01 and 50-328/SS-32-01 Technical Specification 6.8.1 requires that written procedures be implemented covering safety-related activities stated in Appendix A of Regulatory Guide 1.33, Revision 2, which includes the use of surveillance procedures. The licensee eatablished Surveillance Instruction (SI) 240, Functional Test of Control Room Air Intake chlorine Detection System, to comply with Technical Specification surveillance requirement 4.3.3.6.
Contrary to the above. SI-240 was not implemented in that, on August 27, 1985 a technician failed-to place switch HS-43-205B in the test position prior to introducing chlorine fumes into the control Room Air Intake Chlorine Detection System.
This resulted in an engineered safety feature actuation (control room isolation).
This is a Severity Level V violation (Supplement I).
This violation applies to both units.
1.
Admission or Denial of Alleged Violation TVA admits that the violation oc:urred as stated.
2.
Reason for the Violation The violation occurred due to personnel error in that the instrument maintenance technician did not place the chlorine detector handswitch in the test position as required by SI-240.
We disagree with the statement in paragraph 10.a. of the inspection report, that the technician continued the performance of the surveillance after the control room isolation (CRI) without notifying operations personnel. An investigation of the incident revealed that the technician did place the detector handswitch in the test position before notifying operations; however, he did not continue the surveillance until after notifying operations personnel that he had caused the CRI.
This disagreement has been discussed with SQN's senior resident inspector, and he confirmed that his intention was to identify that the technician operated the detector handswitch prior to notifying operations and not to imply that the technician continued to perform the SI without notifying operations of the CRI.
