ENCLOSURE 1
NOTICE OF VIOLATION Tennessee Valley Authority Browns Ferry 1, 2, and 3
Docket Nos.
50-259, 50-260, and 50-296 License Nos.
DPR-33, DPR-52, and DPR-68 During the Nuclear Regulatory Commission (NRC) inspection conducted on February 22 - March 13,
- 1991, a violation of NRC requirements was identified.
The violation involved failure to fol.low procedures for refueling.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement, Actions,"
Appendix C (1990),
the violation is listed below:
Technical Specification 6.8. 1. 1 requires that written procedures shall be established, implemented, and maintained covering the applicable procedures in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Appendix A of Regulatory Guide 1.33 includes procedures for refueling.
Refueling Operations Procedure, 2-GOI-100-3, implements this requirement for refueling.
Procedure step 3. 1 under Precautions and Limitations requires that refueling shall be immediately halted upon occurrence of (procedure step 3.1. 1) unexplained or abnormal increase in source range monitors (SRMs) or fuel loading chambers
{FLCs) re'adings, or {procedure step
- 3. 1.3), loss of neutron monitoring with less than two SRMs/FLCs operable and responding with one in the fuel hand'ling quadrant and one in an adjacent quadrant.
Contrary to,the
- above, neither of the requirements were met in that refueling was not immediately halted when an unexplained increase in FLC 8 reading occurred on February 21, 1991, prior to and during loading of the first fuel assembly into its designated core location.
High and high-high count rate alarms were received prior to fuel handling on February 21,
- 1991, which resulted in work request C042091.
Spiking of the period meter and ramping of the count rate meter occurred while the fuel grapple or refueling bridge were moved prior to and during placement of the first fuel assembly into the core.
This is a Severity Level IV Violation (Supplement I) applicable to all three units.
