| 24-HOUR 91-01 BULLETIN RESPONSE |
| |
| At 1400, on 9/4/01, the Plant Shift Superintendent (PSS) was notified of an |
| NCSA violation that had occurred at the C-355 air plant. Immediately after |
| switching drying units at the air plant, a high-high moisture alarm was |
| received. The alarm indicated air moisture content greater than 1300 ppm |
| water, violating NCSA GEN-10-01. NCSA GEN-010 credits the dry air system |
| for producing dry air with moisture content of less than 1300 ppm. The |
| purpose of this requirement is to prevent exposure of fissile uranium |
| deposits to a moderating environment. No equipment containing fissile |
| material was exposed to high moisture content plant air at the time of the |
| alarm or following receipt of the alarm. |
| |
| Since one leg of double contingency was lost, this is being reported to the |
| NRC as a 24-hr. event report. |
| |
| SAFETY SIGNIFICANCE OF EVENTS: |
| There was no purging of equipment containing fissile material in progress at |
| the time of the moisture excursion. Although a parameter was exceeded, the |
| proper response to the alarm was taken prior to resuming buffering of |
| purging equipment containing fissile material. |
| |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED(BRIEF SCENARIO(S) OF HOW CRITICALITY |
| COULD OCCUR: |
| In order for a criticality to be possible. Operations personnel would have |
| had to fail to respond to the alarm. In addition, a fissile deposit |
| containing greater than a critical mass and absorbing greater than 10 kg of |
| water would have had to be present. |
| |
| CONTROLLED PARAMETERS (MASS, MODERATION. GEOMETRY, CONCENTRATION. ETC: |
| Double contingency for this scenario is established by implementing two |
| controls on moderation. |
| |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE CRITICAL MASS): |
| n/a |
| |
| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| Double contingency for this scenario is established by implementing two |
| controls on moderation. |
| |
| The first leg of double contingency Is based on receiving a high-high |
| moisture alarm indicating a moisture content greater than 1300 ppm water and |
| ceasing buffering and purging operations in response to the alarm. This |
| control was not violated. |
| |
| The second leg of double contingency is based on the dry air system |
| producing plant air with a moisture content less than 1300 ppm water. Since |
| the moisture content was confirmed to be greater than 1300 ppm, this process |
| condition was exceeded and double contingency was not maintained. |
| |
| Since double contingency is based on two controls on moderation, double |
| contingency was not maintained. |
| |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEMS AND WHEN EACH WAS IMPLEMENTED: |
| No corrective actions implemented. Proper procedure response was performed. |
| |
| The NRC Resident Inspector was notified. |
| |
| * * * UPDATE ON 09/12/01 AT 1455 ET BY PITTMAN TAKEN BY MACKINNON * * * |
| |
| Criticality Safety Incident Report NCS-INC-01-022 has been revised to |
| include information from EN-C-826-01-039 that documented that the moisture |
| content did not exceed the NCS limit of 1300 ppm. Since the moisture limit |
| for the plant air system was not exceeded, no violation occurred. R3DO |
| (Sonia Burgess) notified. |
| |
| The NRC Resident Inspector was notified of this update by the certificate |
| holder. |

| MISSING TROXLER DENSITY GAUGE. |
| |
| |
| Western Technologies, out of Albuquerque, accidentally left a 3430 Troxler |
| moisture density gauge at mile marker 49 on US highway 550. The moisture |
| density gauge was out of its transport case laying on the side of the |
| highway when the it was left behind. The driver immediately, within an hour, |
| returned to the location and discovered that the gauge was missing. State |
| of New Mexico has recommended to the licensee that they offer a reward for |
| the missing gauge. |

| MISSING 94 PALLADIUM SEEDS. |
| |
| Licensee received, in the mail, a box containing 94 palladium seeds with a |
| total activity of 119.14 millicuries on Friday, 09/0701 at approximately |
| 1200 ET. The box containing the seeds was locked in the Hot Lab at |
| approximately 1700 hours on 09/07/01. Saturday morning it was noticed that |
| the box containing the palladium seeds was missing. It was assumed that the |
| box of seeds had been picked up. Today, 09/11/01, at 0700 hours a |
| Radiation Physicist came to pick up the box of palladium seeds. At this |
| time it was realized that the seeds were missing. A search of the hospital |
| areas, trash, etc., was performed and the seeds were not found. The |
| hospital security and the Jeffersonville Police department were notified of |
| the missing palladium seeds. |

| AUTOMATIC REACTOR TRIP DUE TO TURBINE/GENERATOR TRIP |
| |
| The plant sustained a turbine/generator trip resulting in a reactor trip, |
| all rods inserted fully, all systems functioned as required unless otherwise |
| noted, and the plant is stable in MODE 3 (Hot Standby). Main feedwater was |
| lost due to a loss of power to the secondary pumps. Power is being supplied |
| from the startup transformer, reactor coolant system is in forced |
| circulation, emergency feedwater is supplying the steam generators, and |
| turbine bypass valves to the condensers are providing a heat sink. |
| |
| The licensee is investigating the cause of the turbine/generator trip and |
| the loss of power to the secondary pumps. |
| |
| The licensee notified the NRC Resident Inspector. |
