NPF-80 During an NRC inspection conducted on August.14-18, 1989, a violation of NRC )

requirements was identified. The violation involved three examples of the failure to follow procedures. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2 Appendix C i (1989) (Enforcement Policy), the violation is listed below:

Failure To Follow Procedures Technical Specification 6.8.1 requires, in part, that procedures shall be established and implemented covering the activities recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.

Section 7.a(1) of Appendix A addresses the collection, filtering, evaporating and concentrating, and demineralizing of liquid radioactive waste.

Administrative Procedures OPGP03-ZA-0010. " Plant Procedure Compliance, Implementation, and Review," Revision 11, and OPCP01-ZA-0002, " Plant Chemical Procedures and Forms," Revision 2, implement this requirement.

I Contrary to the above:

1. On August 10, 1989, at 8:40 a.m., during the routine shutdown activities associated with the gas stripper, Manual Valves 1-XWL-0392 i (Gas Stripper Steam Inlet Isolation) and 1-XWL-0349 (Auxiliary Feed l Pumps 1A Discharge Valve) were not closed as required in i Steps 4.3.6.1 and 4.3.6.4.b of Procedure IPCP13-WL-0007, " Waste '

Evaporator Operations," Revision 4 (February 28.1989). The open l valves established a flow path from the radioactive liquid waste .

system through the shutdown gas stripper into the auxiliary steam I condensate drains system, causing the contamination event. The valves remained open until closed by the licensee on August 14,^1989, at about 3 p.m., during followup of the contamination event.

2. On August 10, 1989, the auxiliary boiler dearcator tank was drained into the inorganics basin as necessary to maintain the tank level in the normal range utilizing the 2-inch Manual Grab Sample l Valve 0-AS-0231. The use of the 2-inch sample valve as a drain valve I

was not addressed in the approved procedures for the auxiliary steam  ;

system (OPOP02-AS-0001 Revision 7), the liquid waste processing systemsteamandcondensatereturns(IPCP13-WL-0010, Revision 5),or 8910030331 8009:5 FDR ADOCK 05000493 0 1:OC

/

the inorganics basin (OPCP11-NC-0001, Revision 3). The manual, intermittent flow path resulted in the transfer of contaminated liquid to the inorganics basin from the auxiliary steam condensate l drains system via the auxiliary boiler deareator tank.

3. On August 12, 1989, at about 5 p.m., during the shutdown activities associated with routine operations of the gas stri Manual Valves 1-XWL-0392.(Gas Stripper Steam Inlet Isolation)pper, and 1-XWL-0349 (Auxiliary Feed Pump 1A Discharge Valve) were again not closed as required in Steps 4.3.6.1 and 4.3.6.4.b of Procedure 1 PCP13-WL-0007, " Waste Evaporator Operations," Revision-4 (February 28,1989). The open valves (initially left open on'  !

August 10,1989) could have resulted in the transfer of additional radioactive liquid into the auxiliary steam condensate drains system.

The valves remained open until closed by the licensee on August 14, 1989, at about 3 p.m., during the followup of the contamination event.

This is a Severity Level IV violation. (Supplement 1)(498/8935-01; 499/8935-01)

Pursuant to the provisions of 10 CFR 2.201, Houston Lighting & Power Company is - i hereby required to submit to this office, within 30 days..of the date of the '

letter transmitting this Notice, a written statement or explanation in reply, including for each violation: (1) the reason for the violation if admitted. ~ l (2) the corrective steps which have been taken and the results achieved,  !

(3) the corrective steps which will be taken to avoid further. violations, and i (4) the date when full compliance will be achieved. Where good cause is_shown, I consideration will be given to extending the response time.-  ;
