| POSSIBLE DAMAGED THICKNESS GAUGE |
| |
| The licensee reported a strip break on the #6 continuous galvanizing line |
| struck a NDS Model #200 (Serial #2061T) thickness gauge and knocked it from |
| its mount. The gauge contains a sealed source of 2 curies of Americium-241. |
| The area was isolated and a survey and wipe test indicated normal readings |
| as indicated by recent surveys. The licensee notified its contractor, Val |
| Met, who will actually go the plant to move the gauge and verify any actual |
| damage to the gauge. Val Met is the company that replaced NDS. |
| |
| No injuries, personnel exposures, or contamination occurred in this |
| incident. |

| 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. |
