Attachment H ST-HL-AE-4547 Page 1 of 4 Reply To Notice of Violation 9322-01 Statement of Violation:

Technical Specification 6.8.1.a states that written procedures shall be established, implemented, and maintained covering the '

activities referenced in Appendix A of Regulatory Guide (RG) 1.33, Revision 2, February 197 Paragraph 1.g of RG 1.33, Appendix A, recommends that administrative procedures addressing shift and relief turnover should be implemente Paragraph 3.2.5 of Procedure OPOP01-ZQ-0022, " Plant Operations Shift Routines," Revision 2, states, in part, that each individual relieving a watchstation SHALL be fully aware of plant status prior to assuming the watc In addition, Paragraph S.3.1.11 of Procedure OPOP01-ZQ-0022, " Plant Operations Shif t Routines," Revision 2, states, in part, that while conducting local operator rounds, individuals should inspect all areas and equipment, ensuring that all noise and vibration levels are norma Contrary to the above, the following two examples of operators failing to meet watchstanding requirements were identified: On Juine 12, 1993, the oncoming Unit 2 operations shift failed to conduct an adequate review of the current plant conditions and were not aware that component cooling water was isolated from the spent fuel pool heat exchanger, which caused a loss of spent fuel pool cooling. This failure to be fully aware of plant status prior to assuming the watch contributed to the loss of spent fuel pool cooling for approximately 13 hour1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> . On June 13, 1993, the Unit 2 mechanical / electrical auxiliary building reactor plant operator failed to note, on a tour of the fuel handling building, that the noise level in the area of the spent fuel pool pumps and heat exchangers was significantly reduced following isolation of component cooling water to the inservice spent fuel pool heat exchange This failure to ensure that all

,

equipment noise and vibration levels are normal l

contributed to the loss of spent fuel pool cooling for approximately 13 hour1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> These two examples constitute one Severity Level IV violation (Supplement 1) (499/9322-01).

Attachment ST-HL-AE-4547 Page 2 of 4 Response to Example Failure of control room operators to be r, fully aware of plant status prior to assuming the watc f I Houston Lichtina & Power Position:

HL&P concurs that the violation occurre I III. Reason for yiolation:

l The reason for this violation was operator inattention to detail and less than adequate control board walkdowns during turnovers and the regular shif t control board waM lowns. This inattention caused the operators to fail to nocice control board indications of the isolated CCW flow during and following the isolation of flow to the Spent Fuel Pool (SFP)

heat exchange ]

- I _ Corrective Actions: ,

Houston Lighting and Power implemented the following l corrective actions following the June 13-14, 1993 loss of l spent fuel pool cooling even l Station Management has emphasized the need for control board awareness in meetings with all active shift l supervisor J J Discussions of issues associated with the loss of spent i fuel pool cooling event were conducted with all on-shif t i licensed personne i Operations department personnel involved in this event received discipline in accordance with the HL&P Constructive Discipline Progra . Management oversight of daily operations department activities has been increase (

) Station procedures covering loss of applicable Class 1E 'i distribution panels have been revised to alert operators l to the potential for valve movement when these panels are re-energize . Approval has been granted for Engineering to carry out the development of a design change to install an annunciator in the control room to alert the operators of a loss of spent fuel pool cooling due to a loss of CCW or spent fuel pool cooling flo MISC 93\93 229.003 I

ST-HL-AE-4547 Page 3 of 4 I Corrective Actions: (Cont'd) HL&P has modified the simulator training portion of its operator training program by randomly including simulator scenarios that contain mispositioned components. -These scenarios are being used to demonstrate operator awareness of mispositioned components during turnover an normal control board walkdown The following action will be performed to ensure future operator understanding of the significance of spent fuel pool coolin . HL&P will revise Licensed Operator Training and continuing training to increase operator awareness that loss of spent fuel pool cooling is a loss of decay heat removal. This action will be complete by September 15, 199 . pate of Full Compliance: *

The South Texas Project is in full complianc Response to Example Failure to ensure noise and vibration levels are normal during operator round ;

I Houston Lightinct & Power Position:

HL&P does not deny this violatio III. Reason For Violation:

The reason for this violation was an RPO's failure to recognize and report the noise level change during normal operator round I Corrective Actions:

The proper performance of operator rounds, including awareness of plant conditions through sensory perceptien, is being emphasized and will continue to be emphasized by Operations supervisio This includes being aware of such things as changes in noise or vibration levels that result from changes in the operating condition. This issue has been covered in meetings with all active Reactor Plant Operator M'sc-93\93 229.003
