NRC STATEMENT"0F VIOLATION A CFR 50 Appendix B Criterion II, " Quality Assurance Program," requires the licensee to implement a quality assurance program that "shall be documented in writing, and carried out throughout plant life."

The licensee's Quality Assurance Manual,Section II, describes the licensee's Quality Assurance program. Attachment 2.1 of Section II incorporates ANSI standard N4.5.2.3, " Housekeeping During the Construction Phase of Nuclear Power Plants," and NRC Regulatory Guide 1.39,

"

Housekeeping Requirements for Water Cooled Nuclear Power Plants" into the progra Regulatory Guide 1.39 Section C.3 states that ANSI N45.2.3 is applicable for housekeeping requirements during the operations phas ANSI N45.2.3, Section 3.5 lists housekeeping inspection requirements and requires surveillance over installed items to assure adequacy of protection from movement of materials or equipment and other factors which may result in damage to installed item The licensee's Quality Assurance Manual,Section II, Attachment 2.2, Exception No. 4, concerning housekeeping states that " Appropriate procedures will be written and implemented."

Administrative Procedure AP-18, Plant Housekeeping and Inspection, Section 3.13 states:

"Hork carried over from one workday to another shall be cleaned up and tools, materials, and equipment stored in a neat manner at the end of the workday."

Contrary to the above, on November 14, 1988: Portable lead shielding on rollers was unsecured adjacent to vital equipment in the east and west decay heat system cooler rooms in the auxiliary building, Several unsecured carts on rollers were unsecured adjacent to vital equipment in the "B" and "D" channel EFIC rooms in the NSEB and the west 4160 volt switchgear room in the auxiliary buildin A strip chart recorder on a cart on rollers was tied to the "A" channel cabinet of the Emergency Feedwater Initiation and Control System (EFIC) with the cabinet door open in the NSE A ladder was tied with a rope to a safety related electrical conduit A57042 in the Nuclear Service Electrical Building (NSEB).

This is a Severity Level IV Violation (Supplement I).

DISTRICT. RESP 0NSE TO VIOLATION A I l Admission or denial of alleged violation: l The District acknowledges and admits that the above occurred as stated except for item 'a' of Violation i Temporary lead shielding is controlled in accordance with Administrative i Procedure AP.305-30 " Temporary Lead Shielding," which is part of the i Radiation Control Manual. Lead Shield Tag No. 85-07 and associated-Temporary Lead Shield file 85-07 provides Engineering evaluation for this installation, Operations concurrence, and Radiation Protection control and periodic inspection of the shieldin In addition, the mobile shield racks have in-place wheel locks for the roller . Reason for the violation:

Administrative Procedure AP.18 " Plant Housekeeping and Inspection" and Maintenance Administrative Procedure MAP-0002 " Control of Maintenance Activities" did not provide proper guidance to plant workers on securing temporary equipment, apparatus and tools within the vicinity of safety related equipment. Also, these procedures did not provide proper instruction forbidding the securing of temporary equipment, apparatus and tools to safety related components when there is a possibility of damage to the component Plant workers followed the above procedures as understood, but did not realize they were in violation of A).18 until explained to them following NRC identification of the proble . Corrective actions taken and results achieved:

The housekeeping problems were immediately corrected upon notification to plant personnel by the NRC Inspector on November 14. Following identification of a ladder secured to safety related conduit on November 27, plant personnel immediately removed the ladde The importance of good housekeeping and protecting safety related components from potential damage has been emphasized in the weekly maintenance meetings since identification of the housekeeping violatio . Corrective actions to avoid further violations:

Maintenance Administrative Procedure MAP-0002 will be revised to:

  • Add a note stating that tools, carts, scaffolding, or other temporary apparatus shall not be lashed / tied off to safety related conduit, piping, or plant equipment which could be damaged as a result of such action * Add a step requiring workers to secure temporary equipment, apparatus and tools within the immediate vicinity of safety related plant components to prevent undesirable movemen l l

"The originator shall deliver the Potential Deviation from Quality (PDQ) report to the Operations Technical Advisor (OTA) within four (4)

hours from the time of identification."

Contrary to the above,-on October 26, 1988, a PDQ reporting that the dissolved oxygen concentration in the main feedwater had exceeded the limit specified in licensee procedure RSAP-0222 was not delivered'to the OTA within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of identificatio This is a Severity Level IV Violation (Supplement I).
