| 24-HOUR NRC 91-01 BULLETIN REPORT INVOLVING THE LOSS OF GEOMETRY CONTROL |
| DURING FEED PRESS OPERATION |
| |
| "At approximately 0645 on January 10, 2000, during routine operations |
| surveillance, operators discovered a mechanical failure inside an enclosed |
| press feed station. The Silletta feeder assembly rubber boot de-coupled from |
| the lower metal pipe and allowed UO2 powder to spill inside the dump hood. |
| The spill resulted in a loss of geometry. Moderation control remained |
| intact, thus no unsafe condition existed. |
| |
| "Controls were reestablished within 4 hours, by cleanup of the spilled |
| material and placement into favorable geometry 3-gallon containers. This |
| event is reported pursuant to NRC Bulletin 91-01 (within 24 hours) due to |
| loss of geometry control. The gad press feed station has been shutdown |
| pending investigation and implementation of corrective actions. |
| |
| "SAFETY SIGNIFICANCE OF EVENTS: Low safety significance - actual powder |
| spill occurred inside hood containment - moderation control remained |
| intact. |
| |
| "POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO(S) OF HOW |
| CRITICALITY COULD OCCUR): Multiple failure modes required before a |
| criticality accident could occur. |
| |
| "CONTROLLED PARAMETER(S) (MASS, MODERATION, GEOMETRY. CONCENTRATION. ETC.): |
| Geometry - analyzed safe geometry equipment; Moderation - limited to dry UO2 |
| powder (not more than 50,000 ppm H2O equivalent moderation) |
| |
| "ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE CRITICAL MASS): Net UO2 spilled material removed was |
| 75.13 kg (2.97% enrichment) with 5,211 ppm H2O actual moderator content. |
| Moderation control remained intact - safe hemisphere mass at 50,000 ppm H2O |
| is ~600 kgs UO2 (at 5.00% U235 enrichment). |
| |
| "NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: Geometry control on the rubber boot clamp |
| and cable lanyards failed, allowing rubber boot to de-couple from feed |
| pipe. |
| |
| "CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEMS AND WHEN EACH WAS |
| IMPLEMENTED: |
| 1. Gad press feed station shutdown. |
| 2. NSE direction of spilled material removal. |
| 3. Investigation and implementation of corrective actions pending." |
| |
| The licensee will inform both local/state representatives and the Region II |
| based Inspector. |
