SUBJECT: EXERCISE OF ENFORCEMENT DISCRETION | |||
(NRC INSPECTION REPORT NOS. 50-413. 414/97-04) | |||
This letter refers to an inspection conducted during the period January 6 | |||
through 23, 1997, at your Catawba Nuclear Station. During the inspection, the 1 | |||
NRC examined the facts and circumstances surrounding your identification of a | |||
design deficiency associated with the Unit 1 and 2 Auxihary Feedwater (AFW) | |||
System. On January 9, 1997, you submitted Licensee Event Report (LER) | |||
, No. 50-413/96-012 following the determination that the AFW system was outside ' | |||
its design basis. Subsequently, on January 17, 1997. Revision 1 to the LER | |||
was submitted to provide additional information and corrective actions. Our | |||
review of this issue is discussed in detail in the subject inspection report | |||
- | |||
transmitted to you by letter dated January 31, 1997. | |||
Based on the information develo)ed during the inspection, the NRC has | |||
determined that a violation of 1RC requirements occurred. Specifically, from | |||
' | |||
initial construction of Units 1 and 2 until December 11. 1996, measures were | |||
not established to correctly translate the design basis of the AFW system . | |||
described in the Final Safety Analysis Report. Section 9.2.1 into | |||
specifications, drawings, and procedures for the Nuclear Service Water (NSW) | |||
System (the assured water source for the AFW system) resulting in the | |||
, | |||
requirements of Technical Specification (TS) 3.7.2.1 not being met for both | |||
units. Because the AFW systems' assured source lacked adequate train | |||
separation, a single, active failure of one of the two assured source suction | |||
valves (1/2RN-250 or 1/2RN-310) would render all three AFW pumps for the | |||
associated unit inoperable under certain conditions. Specifically, with all | |||
three AFW pumps running with high flow demand ar,a a loss of the normal suction | |||
sources (non-safety related), a single failure of one of the two assured | |||
source suction valves would cause the remaining train of the assured source to | |||
attempt to supply all three AFW pumps. This would result in inadequate net | |||
positive suction head to all three pumps, rendering them inoperable. | |||
In accordance with the " General Statement of Policy and Procedures for | |||
Enforcement Actions" (Enforcement Policy). NUREG-1600. this violation normally | |||
would be categorized as a Severity Level III violation. However, as discussed | |||
in Section VII.B.3 of the Enforcement Policy. the NRC may refrain from issuing | |||
a Notice of Violation (Notice) and proposing a civil Jenalty for a Severity | |||
Level III violation that involves a past problem, suc1 as an old engineering. | |||
design, or installation deficiency, provided that certain criteria are met. | |||

After review of this violation and consultation with the Director, Office of | |||
Enforcement the NRC has concluded that the criteria for enforcement | |||
, discretion have been met. Therefore, to encourage licensee efforts to | |||
identify and correct subtle violations before degraded safety systems are | |||
called upon to function, no Notice is being issued in this case. The specific | |||
bases for this decision are: (1) you identified the violation during a | |||
, licensee-initiated design review conducted in support of a modification: | |||
(2) although voluntary self-initiated technical audits had beer 1 performed for | |||
both the AFW =and NSW systems, it was not unreasonable tha' these audits did | |||
not identify the deficiency earlier, and it is unlikely the deficiency would | |||
' | |||
have been identified by routine surveillances or quality a surance audits: | |||
(3) timely and appropriate modifications were completed to mstall check | |||
valves in locations to resolve the deficiency: (4) timely and effective | |||
corrective actions were implemented, and appropriate long-term corrective | |||
actions to review and identify any similar design deficiencies in the systems | |||
interfacing with the Standby Shutdown System were delineated; and (5) the | |||
design deficiency occurred at the time of plant construction and is not | |||
reasonably linked to present engineering performance. | |||
This letter serves to document the closure of the ap)arent violation | |||
(eel 50-413 and 50-414/97-04-01) described in the su) ject inspection re) ort | |||
and completes the NRC's action in this matter. No formal response to t1is | |||
letter is required. In accordance with 10 CFR 2.790 of the NRC's " Rules of | |||
Practice," a copy of this letter will be placed in the NRC Public Document | |||
Room. | |||
