| that numerous sprinkler heads were corroded, affecting 16 sprinkler systems |
| in C-337 and one system in C-333, such that the ability of the sprinklers to |
| flow sufficient water was called into question. Subsequently, these |
| sprinkler systems were declared inoperable, and TSR-required actions |
| establishing roving fire patrols were initiated. This deficiency was |
| detected during scheduled system inspections conducted by Fire Protection |
| personnel. Currently, functionality of the sprinkler heads has not been |
| fully evaluated by Fire Protection personnel, and the remaining cascade |
| buildings are currently being inspected, and if necessary, this report will |
| be updated to identify any additional areas. |

| THE LICENSEE DETERMINED A CONDITION THAT WOULD HAVE PREVENTED THE CVC SYSTEM |
| FROM FULFILLING ITS INTENDED SAFETY FUNCTION. |
| |
| At 1643 CDT on 8/2/99 with charging pumps 'A' and 'B' operating, the control |
| room received the "CHARGING HEADER FLOW LO" annunciator. The operator |
| observed that charging header flow indicated 0.0 gpm. The control room |
| personnel selectively secured charging pump 'A' and observed that the |
| charging header flow returned to the expected flow (44.0 gpm) for a single |
| operating charging pump. At 1650 charging pump 'A' was restarted to |
| investigate if the condition was repeatable. Operations personnel were |
| observing the charging pumps locally during this period. The condition was |
| identified as repeatable, however, operations personnel could not |
| conclusive identify locally any abnormalities. Charging pump 'A' was |
| declared inoperable and was secured in the "OFF" condition to preclude any |
| unplanned starts due to automatic actuations (pressurizer level deviation or |
| SIAS) and Technical Specification 3.1.2.4 was entered at 1654 (CDT). The |
| on-coming shift isolated and danger tagged charging pump 'A'. After review |
| of the information by licensing personnel on August 3, 1999, it was |
| determined that this failure may have prevented the CVC System from |
| fulfilling its intended safety function. |
| The plant was in a 72 hr LCO action statement to have both charging pumps |
| operable while in modes 1,2,3, & 4. The plant entered mode 5 within the 72 |
| hr action statement. The cause of the problem is being investigated. |
| |
| The resident inspector will be notified. |
| |
| ***RETRACTION on 08/10/99 at 1107 ET by Arthur Wemett taken by MacKinnon*** |
| |
| |
| A team was appointed to investigate the event that was observed on August 2, |
| 1999. Plant data and discussions with individuals were performed to |
| identify pertinent facts and potential failure modes. Additional |
| troubleshooting was performed August 6, 1999 to confirm which components |
| were operating correctly or possibly failed. The result of the |
| troubleshooting concluded that a failure of the charging flow transmitter |
| was occurring at low pressures (indicator was sporadic). The flow was |
| verified by other plant parameters (i.e., temperatures, pressures, and |
| levels) and by the use of a temporary installed ultrasonic flow meter. The |
| transmitter was removed from service and replaced. The transmitter was |
| tested by maintenance and the failure could be repeated. |
| |
| The failure of the charging flow transmitter gave the indication that |
| charging flow was lost but at no time during the plant evolution was actual |
| flow lost. Based on this information we are retracting the four hour |
| notification under 10CFR50.72(b)(2)(iii)(D) that was made on August 3, |
| 1999. |
| |
| HOO notified R4DO (Powers). |

| BULLETIN 91-01 24 HOUR REPORT |
| |
| Operations personnel during a walkdown of the seal exhaust system discovered |
| that a nuclear criticality safety analysis (NCSA) requirement, maximum oil |
| volume, could not be verified when an oil level was observed in the pumps |
| separator's sight glass. The pumps in question were used for the highly |
| enriched uranium (HEU) program, and after it's suspension, prior to March |
| 1997, the pumps were placed out of service. Visible oil level in the sight |
| glass without supporting documentation for oil capacity of these pumps |
| constitutes a loss of one control (Volume) for double contingency. The |
| second control (Interaction) was maintained. |
| |
| There was no loss of hazardous/radioactive material or |
| radioactive/radiological contamination exposure as a result of this event. |
| |
| The licensee notified the NRC resident inspector and DOE. |

| COURTESY CALL REGARDING DISCOVERY OF FISH KILL IN CIRCULATING WATER INTAKE |
| |
| The licensee notified the Texas State Parks and Wildlife Agency regarding |
| the discovery of several thousand dead shad in the vicinity of the |
| circulating water intake. The state informed the licensee that this |
| discovery was not reportable, hence the licensee is providing this |
| notification to the NRC as a courtesy. The following information was |
| provided by the licensee via facsimile: |
| |
| "Approximately two to three thousand shad were observed floating in the |
| vicinity of the circulating water intake area. No sport fish were observed |
| in this area. The likely cause of the die-off was stress to the shad due to |
| dissolved oxygen depletion and high ambient temperatures. A survey of the |
| main reservoir revealed few (less than ten) floating fish in the main water |
| body. Consequently, this condition appears to be limited to the intake area |
| only. A courtesy call to the Texas Parks and Wildlife was made at |
| approximately 1100 on 08/07/99. The agency indicated that no formal |
| reporting was required. A follow-up survey of the main reservoir on 08/08/99 |
| confirmed that only shad in the intake area remained affected and no |
| floating fish were observed in the main water body of the reservoir. A |
| walk-down of the intake structure on 08/09/99 revealed several thousand |
| floating shad collected in front of the Unit 1 trash racks extending out |
| approximately 10 feet from the trash racks." |
| |
| The NRC resident inspector has been informed of this notification by the |
