NOTICE OF VIOLATION AND PROPOSED IMPOSITION OF CIVIL PENALTIES 1 l

Duke Power Company Docket Nos. 50 269, 270, and 287

- Oconee Nuclear Station License Nos. DPR 38, 47, and 55 Units 1, 2. and 3 EAs 97 297 and 97 298 During Nuclear Regulatory Commission (NRC) inspections conducted from April 22 to June 6,1997, violations of NRC requirements were identified, In

- accordance with the " General Statement of Policy and Procedures for NRC Enforcement Actions," NUREG 1600, the NRC proposes to impose civil penalties pursuant to Section 234 of the Atomic Energy Act of 1954 (Act), as amended. I 42 U.S.C. 2282, and 10 CFR 2.205. The particular violations and associated i civil- penalties are set-forth below:

1. Violations Assessed a Civil Penalty A. Technical Specification (TS) 3.2.1, "High Pressure Injection and Chemical Addition Systems," requires that the reactor shall not be critical unless two high pressure injection (HPI) pumps per unit are operable except as specified in TS 3.3. l TS 3.3.1.a(1), "High Pressure Injection System," requires that when the reactor coolant system (RCS), with fuel in the core. is in a condition with temperature above 350 degrees Fahrenheit (*F) and reactor power less than 60 percent full. power, two independent -

trains, each comprised of an HPI pump and a flow cath capable of taking suction from the borated water storage tant and discharg1ng into-the RCS automatically upon Engineered Safeguards Protective

- System actuation, shall be operable. TS 3.3 1.c(1) further requires that when reactor power is greater than 60 power that the remaining HPI pump shall be operable. percent full Contrary to the above, between at least May 1 and May 2, 1997,-

with fuel in the Oconee Unit 3 core and RCS temperature greater than 350'F the licensee failed to maintain the HPI system operable, as required by TSs, Sxcifically, the licensee operated with the HPI system outside of tie letdown storage tank (LDST) level versus pressure analyzed limitation curve which resulted in all of the HPI pumps being inoperable and unable to perform their safety related function if called upon to operate, due to inadequate net positive suction head.'

This is a Severity Level II violation. (Supplement I)

10 CFR 50, Appendix B, Criterion XVI, " Corrective Action,"

requires, in part, that measures t,9 established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective M terial and equipment, and nonconformances, are promptly identified and corrected.

(1) Contrary to the above, as of April 21, 1997, the licensee failed to establish measures to assur 9 that cracks in High Pressure Injection (HPI) safe end nozzles, adjacent HPI piping, and nozzle thermal sleeves, which are significant conditions adverse to quality, were promptly identified and corrected. Consequently, the licensee did not promptly identify and correct a crack in the safe eno weld of HPI makeup nozzle 2A1 of Oconee Unit 2 that resulted in an unisolable, reactor coolant leak on April 21, 1997. (02013)

(2) Contrary to the above, as of April 21, 1997, the 'icensee i

failed to take corrective action for temperature l

differentials that the licensee measured in June 19% in the safety related HPI makeup piping. These temperature differentials were indicative of thermal stratificatior, in the HPI makeup piping, which is a condition adverse to quality in that such stratification could contribute to HPI pipe cracking.

This is a Severity Level III problem. (Supplement I)

Specifically, level indication remained constant: however, during a reactor cooldown, with the pressurizer being maintained at a constant level, the LDST level is expected to be constantly decreasing, as was demonstrated during the previous shift, when the operations crew repeatedly added water to the LDST (03014) l This is a Severity Level IV violation (Supplement 1).

B. TS 6.1.1.1. requires, in part, lines of authority, responsibility, and communication shall be established and defined for the highest management levels through intermediate levels to and including all-

Enclosure 4.3, ' Dedicated LTOP '

Operator Guidelines," Step 1,3, states: " Prevention of low temperature overpressurization is the on1 of the dedicated low temperature overpres.y responsibility and duty sure protection operator."

Contrary to the above, the licensee failed to operate the station in accordance with approved procedures in that at 11:58 ) m., on May 2, 1997, LTOP operation was established with the 0ATC as the designated dedicated LTOP operator. This resulted in the dedicated LTOP operator having responsibilities for operation of the assigned unit in addition to his responsibility to prevent low temperature overpressurization, (04014)

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

Contrary to the above, on October 21, 1996 and February 22, 1997, the licensee failed to use procedural guidance provided by

-SI/0/A/5090/001 for the-installation of instrument tubing caps, which was required to be used because the technicians performing the maintenance activities were not knowledgeable of tube fitting and tube installation practices. (05014)
