|SUBJECT:||NOTICE OF VIOLATION AND PROPOSED IMPOSITION OF CIVIL
PENALTY - $55,000
(NRC Inspection Report No. 50-546/97009; 50-457/97009)
Dear Mr. Stanley:
This refers to the inspection conducted from May 20 through June 30, 1997, at the Braidwood Unit 1 and Unit 2 reactor facilities. An exit meeting was conducted on June 30, 1997, and the inspection report was issued on August 26, 1997. A predecisional enforcement conference was conducted on September 11, 1997, to discuss the inspection issues related to strict compliance with Technical Specifications (TS) for the Emergency Core Cooling System (ECCS) subsystems. Specifically, these issues are related to the Centrifugal Charging (CV) system, a subsystem of ECCS.
Based on the information developed during the inspection and the information that you provided during the conference, the NRC has determined that a violation of NRC requirements occurred. The violation is cited in the enclosed Notice of Violation (Notice) and Proposed Imposition of Civil Penalty and the circumstances surrounding it are described in detail in the subject inspection report.
The violation in the enclosed Notice involves the failure to strictly comply with TS surveillance test requirement 4.5.2.b(1) which requires the ECCS pump casings and discharge piping high points outside of containment be vented at least once every 31 days. On February 16, 1996, a Braidwood Station system engineer discovered that the CV pump casing and high points were not being vented every 31 days as required. The decision to not strictly comply with the TS was partially based by the Braidwood Station staff on the fact that the CV pump casings did not have vents. A subsequent operability justification determined that the intent of the TS was being met based on factors such as the pressure in the piping and the CV system design and piping configuration. However, this operability justification failed to recognize that TS requirements were not being strictly met and that a TS change was needed. The failure to recognize that the TS requirements were not being strictly met and to seek a TS change was identified by the NRC.
The potential safety consequence of this violation was low. Venting of the ECCS is required to ensure that no air is entrained in the ECCS that could result in water hammer or air binding that could prevent proper pump/system performance. Due to the pressure in the CV system piping and the system configuration, this was not likely to occur. In addition, the ultrasonic testing, performed by the Braidwood Station staff, of selected CV high points found no entrained air. However, while the potential safety consequence is low, the regulatory significance is high. The Braidwood Station staff continued to operate outside of TS requirements even after discovering that the TS was not being strictly complied with and NRC involvement was necessary in order to ensure that strict compliance with the TS requirements and the necessary TS changes were made. The failure to request the necessary TS changes denied the NRC the opportunity to determine whether safety issues were involved.
Based on the foregoing, this violation has been categorized in accordance with the "General Statement of Policy and Procedures for NRC Enforcement Actions" (Enforcement Policy), NUREG-1600 at Severity Level III. In accordance with the Enforcement Policy, a base civil penalty in the amount of $55,000 is considered for a Severity Level III violation. Because your facility has been the subject of escalated enforcement actions within the last 2 years1, the NRC considered whether credit was warranted for Identification and Corrective Action in accordance with the civil penalty assessment in Section VI.B.2 of the Enforcement Policy.
Identification credit was not warranted because Braidwood Station staff had an opportunity to correct the violation in February 1996 when the TS noncompliance was identified. The NRC identified the continued violation of the TS surveillance testing requirements during the 1997 inspection.
Corrective Action credit was warranted based on the corrective actions implemented and discussed at the enforcement conference. The corrective actions included (1) ultrasonic testing inspection of vulnerable areas in the CV system; (2) review of selected TS surveillance tests to verify strict compliance; (3) submittal of appropriate license amendment requests; (4) revision of affected procedures; and (5) distribution of a Station Manager letter which stresses strict compliance with TS requirements.
Therefore, to emphasize the importance of compliance with technical specifications, I have been authorized, after consultation with the Director, Office of Enforcement, to issue the enclosed Notice of Violation and Proposed Imposition of Civil Penalty (Notice) in the amount of $55,000 for the Severity Level III violation.
You are required to respond to this letter and should follow the instructions specified in the enclosed Notice when preparing your response. The NRC will use your response, in part, to determine whether further enforcement action is necessary to ensure compliance with regulatory requirements.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter, its enclosure(s), and your response will be placed in the NRC Public Document Room (PDR).
Sincerely, A. Bill Beach Regional Administrator

NOTICE OF VIOLATION
PROPOSED IMPOSITION OF CIVIL PENALTIES
|Commonwealth Edison Company
Braidwood Nuclear Power Plant Units 1 and 2
Docket No.s 50-456; 50-457
During an NRC inspection conducted on May 20 through June 30, 1997, a violation of NRC requirements was identified. In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the NRC proposes to impose a civil penalty pursuant to Section 234 of the Atomic Energy Act of 1954, as amended (Act), 42 U.S.C. 2282, and 10 CFR 2.205. The particular violation and associated civil penalty are set forth below:
Technical Specification 3.5.2 requires that two independent emergency core cooling system (ECCS) subsystems be operable with the units in Modes 1, 2, and 3 with each subsystem comprised of a) one operable centrifugal charging pump; b) one operable safety injection pump; c) one operable residual heat removal (RHR) heat exchanger; d) one operable RHR pump; and e) an operable flow path capable of taking suction from the refueling water storage tank on a safety injection signal and automatic opening of the containment sump suction valves.
Technical Specification Surveillance 4.5.2.b(1) requires that each ECCS subsystem be demonstrated operable at least once per 31 days by venting the ECCS pump casings and discharge piping high points outside of containment.
Contrary to the above, since commercial operation began in 1987 and 1988, respectively, for Unit 1 and Unit 2 and continuing until May 1997, an ECCS subsystem consisting of the centrifugal charging (CV) pump had not been demonstrated operable at least once per 31 days by venting the casing and CV high points outside containment when the units were in Modes 1, 2, and 3. (01013)
This is a Severity Level III violation (Supplement I).
Civil Penalty - $55,000
Pursuant to the provisions of 10 CFR 2.201, Commonwealth Edison Company (Licensee) is hereby required to submit a written statement or explanation to the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, within 30 days of the date of this Notice of Violation and Proposed Imposition of Civil Penalty (Notice).
