| POTENTIAL RAD GROUND RELEASE PATH DISCOVERED DUE TO LOSS OF SECONDARY |
| CONTAINMENT |
| |
| "This notification is being made pursuant to NRC regulation |
| 10CFR50.72(b)(3)(v)(D), any event or condition that at the time of discovery |
| could have prevented the fulfillment of the safety function of structures or |
| systems that are needed to mitigate the consequences of an accident. |
| |
| "On March 10, 2003 at 22:38, it was determined that the secondary |
| containment was inoperable due to a leak in the Z sump manway gasket. The |
| plant was in Mode 5, shutdown, performing fuel shuffle when secondary |
| containment was declared inoperable. LCO 3.6.4.1 was entered. The fuel |
| shuffle was secured at 22:40 after the completion of the fuel move that was |
| in progress. No additional Core Alterations or OPDRVs [Operations |
| Potentially Draining the Reactor Vessel] were in progress. Upon |
| investigation into the secondary containment operability, it was determined |
| that a non-Tech Spec surveillance performed on dayshift also rendered |
| secondary containment inoperable due to additional leakage pathway via the Z |
| sump. A principal safety function of Secondary Containment is to limit the |
| ground level release to the environs of airborne radioactive materials |
| resulting from a fuel handling accident. |
| |
| "As a result of the alignment of the Z sump the potential existed that if a |
| radioactive release were to occur due to a fuel handling accident, part of |
| the filtered release via Standby Gas Treatment System could be a ground |
| level release vice a release through the Elevated Release Point. The |
| surveillance has been completed and the additional leakage paths that were |
| opened due to the surveillance have been sealed. The leaking manway gasket |
| was determined to be due to not adequately torquing the gasket bolts. The |
| bolts have been retorqued. Secondary containment was reestablished, and was |
| declared OPERABLE at 02:55, 3-11-03. |
| |
| "The NRC Senior Resident has been notified." |

| |
| "THIS IS A RETRACTION OF EVENT #39659. |
| |
| "On 3/10/2003 at 2238 CST, Cooper Nuclear Station made an 8 hour 50.72 |
| non-emergency notification to the NRC per 50.72 (b)(3)(v)(D). It was |
| determined that the secondary containment was inoperable due to a leak in |
| the Z sump manway gasket. The plant was performing fuel shuffle at the |
| time. LCO 3.6.4.1 was entered. The fuel shuffle was secured at 22:40 after |
| completion of the fuel move that was in progress. Investigation determined |
| that a non-Tech Spec surveillance performed on dayshift also rendered |
| secondary containment inoperable due to an additional leakage pathway via |
| the Z sump. As a result of the alignment of the Z sump, the potential |
| existed that if a radioactive release were to occur due to a filet handling |
| accident, part of the filtered release via the Standby Gas Treatment System |
| could be a ground level release. This would potentially result in |
| unacceptable dose levels since DBA calculations assulne an elevated release |
| point for this accident. Thus, the secondary containment would be unable to |
| fulfill its accident mitigation safety function to limit the release to the |
| environs of radioactive materials from postulated design basis accidents |
| (DBA) to control room occupants and off-site. |
| |
| "Further evaluation demonstrated that if a fuel handing accident had |
| occurred at the time of discovery of the condition, the thyroid doses to |
| control room personnel (which are the limiting doses for this accident) |
| would have been less than DBA values. Other doses would remain a small |
| fraction of 10CFR100 and General Design Criteria 19 limits. This is because |
| the plant had been shutdown for 14 days reducing considerably the fuel |
| handling accident source term. In addition, the estimated ground level |
| release flow rate was a small percentage of the elevated release point flow |
| rate. Finally, most of the radiation dose from this accident occurs in the |
| first 90 seconds of the event via the unfiltered Reactor Building exhaust. |
| Therefore, the secondary containment, which includes the Standby Gas |
| Treatment system and the elevated release point, would have performed its |
| accident mitigation safety function and was operable." |

| |
| NRC R4DO (Greg Pick) was notified. |

| REPORT OF EXPOSURE OF LICENSEE EMPLOYEES WAS MADE TO THE STATE |
| |
| The licensee reported the exposure of licensee employees to radiation from a |
| TN Technologies model 5174 (serial # B103) fixed gauge containing a 2 curie |
| Cs-137 sealed source. The gauge fell approximately 6 feet from its location |
| on a coke hopper on approximately 04/03/03. The welds which attached the |
| gauge anchoring bolts appear to have failed. The gauge had been in place |
| since 1992. The gauge fell with the shutter open onto the first landing of |
| the skip pit area. The gauge went un-noticed for a week until April 11 @ |
| 1300 when maintenance workers were called to move what was thought to be a |
| motor (all labels and markings on the gauge were unreadable). The workers |
| spent approximately 1.5 hours rigging and moving the gauge before an |
| individual recognized the gauge and secured the area. A contractor, |
| Radiometrics, was then called in to secure the gauge. The Ohio department |
| of Health was called concerning the incident on April 17 @1400. An on-site |
| investigation was done and a dose assessment of affected personnel is in |
| progress. |

| PROVISIONAL REPORT OF MEDICAL MISADMINISTRATION |
| |
| On 4/22/03, Nuclear Medical Technicians at St. Raphael Hospital received 2 |
| vials ( 75 millicurie each) of I-131 that was to be administered to a |
| patient later that afternoon. The vials were placed in their normal storage |
| location. When the patient arrived, a nuclear technician administered only |
| one vial of the I-131 which only gave the patient half of the prescribed |
| dose. On 4/23/03, while preparing nuclear medicine for a different patient, |
| a technician discovered the second vial of I-131 that was to be administered |
| to the patient from the previous day. Upon discovery, the patient and the |
| prescribing physician was notified of the error. The physician determined |
| that the 27 hour span between doses would have no deleterious effects on the |
| patient so the second dose was administered in the afternoon of 4/23/03. |
| The intended dosage was 150 millicuries and the received dose was 142.4 |
| millicuries. The RSO was notified at 0800 hrs. EDT on 4/24/03 and contacted |
| NRC Inspector Richard McKinley who advised the licensee to make this |
| notification. |

| REACTOR TRIP FROM 100% POWER DUE TO A TURBINE TRIP |
| |
| The licensee reported they had a turbine trip possibly due to the loss of |
| output breakers which resulted in turbine overspeed causing the trip. The |
| reactor trip from 100% was caused by the turbine trip. All rods fully |
| inserted and there was no ECCS actuation, however one PORV lifted and |
| reseated. All three emergency diesel generators auto started and loaded. |
| The 4 reactor coolant pumps lost power, so the reactor was in natural |
| circulation from 1645 to 1823 when they restored one coolant pump. The |
| plant had lost power restored at 1904. They also had their aux. feedwater |
| to auto start as expected due to a low steam generator level. The plant is |
| currently stable and they are investigating the cause of the turbine trip. |

| INTERIM SURVEILLANCE PROGRAM FOR FUEL CHANNEL BOW MONITORING (PART 21) |
| |
| The control rod-fuel channel interference evaluation has been completed. It |
| determined that BWR/6 and BWR/4 & 5 C-lattice plants with GNF thick/thin |
| channels potentially have increased channel bow that can impact fuel bundle |
| lift, loads on reactor internals, and control rod operability. An interim |
| surveillance program has been developed to augment the surveillance |
| requirements in the plant Technical Specifications until other actions, |
| which mitigate or limit the potential for control rod-channel interference |
| due to channel bow can be identified and implemented. The recommendations |
| address the extent and frequency of surveillance actions, and the plants to |
| which they should be applied. This surveillance program provides early |
| indication of potentially degraded operational performance and assurance |
| that action is taken before reaching excessive levels of control rod |
| friction. This surveillance plan is limited to BWR/6 and BWR/4 &5 C-lattice |
| plants with GNF thick/thin channels and GE control rods. There have been no |
| indications of operational or scram problems on BWR/2, 3 and 4 D-lattice |
| plants, and as a result, they are excluded from the interim surveillance |
| program. |
