| Title | Non-Compliance to License Condition Requiring Modifications to LPG Tank was
not Identified During Transition to NFPA 805 |
| Description | The team identified an unsecured 500 gallon (water capacity) LPG storage tank in the Transformer Yard adjacent to the CT1 transformer and the Unit 1 Turbine Building. The LPG storage tank sat on four concrete blocks and did not appear to have an excess flow control valve installed to prevent a large release of propane gas from a ruptured supply line to the Auxiliary Boiler. The licensee had previously identified these problems in PIPs O-06-01385, O-08-02163, O-11-10119 and O-13-03819. Initially, a work request was written to secure the tank but it was later closed without the work being performed. Subsequently, an engineering change request was initiated to address the issue but was never approved. In ONS License Amendment 64 for Unit Nos. 1 and 2 and License Amendment 61 for Unit 3, each units license was amended to state, in part, that The licensee is authorized to proceed and is required to complete modifications identified in Table 3.1 of the NRCs Fire Protection SER dated August 11, 1978. The modifications shall be completed on the schedule specified in Table 3.1. SER Section 3.1.7, states, Propane tanks located outside of the turbine building will be anchored and provided with excess flow valves. Table 3.1 states in part, The modification will be completed by the end of the first refuel outage for any unit which occurs after 6 months from the date of issuance of this Safety Evaluation. A letter from Duke Power Company to the NRC dated June 29, 1979 stated, in part that, The required modification had been completed. When questioned about the current configuration of the tank, the licensee stated that since the transition to their approved NPFA 805 FPP all prior FPP SERs and commitments have been superseded in their entirety by the revised license condition and that the tank was in compliance with the requirements of NFPA 805, Section 3.3.7.1 for the storage of flammable gases located outdoors. Offset distances from the tank to structures, systems or components were judged by the licensee to be sufficient to prevent adverse impact from fires or explosions. The team did not agree with this position and stated that the ONS April 14, 2010 License Amendment Request (LAR) did not address the tank or the non-compliance with the license amendment requirement of 1978. The NRC has requested additional information from the licensee to determine if a prior change to the license, made before the transition to NFPA 805, allowed the tank to remain in its current location without the originally required modifications; and, to determine if the tank had, at one time, been in compliance, but had been improperly relocated under a work order performed in 1986. This issue is unresolved pending NRC review of additional information requested to determine if the issue of concern constitutes a violation of NRC requirements. This issue is identified as URI 05000269, 270, 287/2013007-05, Non-Compliance to License Condition Requiring Modifications to LPG Tank was not Identified During Transition to NFPA 805. |
