DUKE POWER COMPANY McGUIRE NUCLEAR STATION REPLY TO NOTICE OF VIOLATION SUPPLD' ENTAL RESPONSE (Revised)
Violation 369/88-12-04 and 370/88-12-04 B.
10 CFR 50. Appendix B. Criterion XI. requires that a test program be established to assure that all testing required to demonstrate that systems and components will perform satisfactorily in service is identified and performed in accordance with written test procedures.
Contrary to the above. the test program established to demonstrate that the turbine driven auxiliary feedwater pumps will perform satisfactory in service was inadequate.
The procedure used to test the pumps does not perform the test in the as found condition in that the steau lines to the pump turbine are drained of condensate prior to testing.
This is a Severity Level IV (Supplement I) violation.
Response
1.
Admission or Denial of Violation:
This violation is admitted as stated.
2.
Reason for the Violation if Admitted:
The first portion of the violation states that "... the tist program established to demonstrate that the turbine driven auxiliary feedwater pumps will perform satisfactory in service was inadequate". This portion of the violation is admitted. None of the test performed on the turbine driven auxiliary feedwater pumps in order to satisfy the requirements of the Technical Specifications or ASME Section XI demonstrate that the turbine vill perform satisfactorily in service since the turbine steam supply lines were drained prior to performing any tests on the turbine.
The steam supply lines were routinely drained prior to initiation of any tests on the turbine driven auxiliary feedvater pumps. This was done as a "good operating practice" in order to avoid any potential damage to the turbine from condensate which was not expected to be present in the steam supply lines.
In deed, the operating history of the auxiliary feedvater pumps has demonstrated on auto-starts following feedwater transients that the automatic condensate drain feature of the steam supply lines has provided reasonable assurance that condensate vill not accumulate and adversely affect the operation of the turbine.
Page 1 or 2
The second portion of the violation which states "the procedure used to test the pumps does not perform the test I
in the as found condition in that the steam lines to the pump turbine are drained of condensate prior to testing" is not correct. The subject IWP procedure is designed to test the pump ONLY in order to comply with ASME Section XI requirements. The drainirs of the turbine steam supply lines does not tapact or change the as-found condition of the CA pump.
3.
Corrective Actions Already Taken1 No additional corrective actions were taken.
4 Corrective Steps to be Taken to Avoid Further Violations:
Station Operations will place the draining of all steam supply lines on the shift rounds sheets.
Guidance will be provided to help operators identify blockage in the drain line. This will ensure that lines are drained twice a day normally.
Station Performance will revise PT/1-2/A/4252/07, which is performed in accordance with Technical Specification 4.7.1.2.b.3 to prohibit draining of the steam line prior to i
performing the test. This will test the turbine driven auxiliary feedwater pump in the as-found condition.
1 Date of Full Compliancer i
i i
r The station will be in full compliance with corrective measures stated above by October 1,1988.
