| 24-HOUR NRC BULLETIN 91-01 REPORT |
| |
| "During an NCS annual assessment by operations personnel, two cardboard |
| boxes with unfavorable geometry were found inside an area controlled by |
| NCSA-326_014 A02. This Is a violation of control #17 of the NCSA that |
| requires unfavorable items capable of holding solution shall have holes to |
| provide drainage such that no more than one inch of solution can accumulate |
| in them. |
| |
| "This resulted in a violation of the double contingency principle where |
| control was reestablished and is reportable under NRC BL 91-01. |
| |
| "SAFETY SIGNIFICANCE OF EVENTS: |
| |
| "The safety significance of this event is low. The open cardboard box was |
| not under any overflow line or seal exhaust lines and the seal exhaust |
| station is not operating. |
| |
| "POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW |
| CRITICALITY COULD OCCUR): |
| |
| "During operation of the seal exhaust station the contents of the seal |
| exhaust lines could have sprayed in to the box to cause a criticality. |
| |
| "CONTROLLED PARAMETERS (MASS, MODERATION. GEOMETRY, CONCENTRATION,
ETC.): |
| |
| "The first control was the requirement to have drainage holes in unfavorable |
| geometry containers. The second control was that it was unlikely an |
| unfavorable geometry container would be positioned in a location that seal |
| exhaust oil would spray into the container. |
| |
| "ESTIMATED AMOUNT. ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE
PROCESS |
| LIMIT AND % WORST CASE OF CRITICAL MASS): |
| |
| "The licensed material would be UF4 in oil with a maximum enrichment of 20% |
| U-235 |
| |
| "NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND
DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| "Control #17 of the NCSA that requires unfavorable items capable of holding |
| solution shall have holes to provide drainage such that no more than one |
| inch of solution can accumulate in them. |
| |
| "CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS
IMPLEMENTED: |
| |
| "The cardboard boxes were removed from the area controlled by |
| NCSA-326_014.A.02" |
| |
| The NRC resident inspector has been informed of this event by the licensee. |

| ERDS INOPERABLE DUE TO PLANNED OUTAGE OF THE PLANT PROCESS COMPUTER
SYSTEM |
| (PPCS) |
| |
| AT 1232 CT, the Point Beach Nuclear Plant ERDS became inoperable as a result |
| of modifications to change out the plant process computer system (PPCS). |
| This is a planned evolution. ERDS will remain inoperable until |
| approximately, December 18, 2001. |
| |
| This information was verbally provided to a representative of NRR during the |
| week of 10/15/2001. The senior resident inspector has also been briefed on |
| the modifications and schedule. NMC to NRC letter (NRC 01-0080) dated |
| 11/21/2001 stated we would be submitting this Non-Emergency report. |

| At approximately 1745, the control room was notified of heavy smoke. At |
| 1815, the licensee declared an Unusual Event based on a small fire in the |
| industrial area of the plant lasting greater than 15 minutes. Preliminary |
| indications revealed that the incident may have been related to an |
| electrical fire involving the heating element or switch of a drum dryer |
| located in the old chemistry lab. There was no release of radiological or |
| hazardous materials, and there were no personnel injuries. |
| |
| The Fire Department is currently on site, and the fire is believed to be |
| under control. The control room is currently waiting for confirmation that |
| the fire is out in order to terminate the Unusual Event. |
