|                                                                              |
| The event took place at a coal plant where a nuclear gauge is installed on a |
| coal chute.  Not following established maintenance procedures led to workers |
| entering the chute with the source exposed.  A field of approximately 450    |
| mr/hr was created.  Whole body exposure was calculated based on a five hour  |
| stay time resulting in an estimate of 2.25 Rem for the most exposed          |
| individual.   Two other individuals were involved with lower total exposure. |
|                                                                              |
|                                                                              |
| The source involved is believed to be Cs-137 with an activity between 100    |
| and 200 mCi.                                                                 |

| Four workers were exposed instead of three and all four of the workers were  |
| radiation workers for the Neb Public Power District.  Calculated whole body  |
| radiation exposure to the four workers:  2250 mrem, 1361 mrem, 611 mrem, and |
| 450 mrem.  The whole body dose was based on total exposure time multiplied   |
| by the maximum measured rate at the beam port, 450 mrem/hr.  The individuals |
| were approximately one foot away from the beam port                          |
|                                                                              |
| The operations center informed the R4DO (Shackelford) and NMSS EO (Hickey).  |

| A manual scram was inserted at 0009 on 5/8/01.  The scram was conducted in   |
| accordance with plant procedures, IOI-8 "Manual Scram," due to a failure of  |
| the reactor recirculation pump "A" to restart during a downshift from fast   |
| to slow speed operation.  Plant response to the manual scram was as          |
| anticipated, all rods fully inserted, no ECCS actuations occurred and no     |
| SRVs opened.  Reactor vessel water level reached Level 3 (177.7 inches) and  |
| operators entered the Plant Emergency Instructions.  At 0016 the Plant       |
| Emergency Instructions were exited.  The cause of the "A" recirculation pump |
| failure to restart is being investigated.                                    |

| TECH SPEC REQUIRED SHUTDOWN                                                  |
|                                                                              |
| On 5/8/01, at approximately 1004, the Hope Creek Generating Station          |
| initiated a unit shutdown to comply with the provisions of Technical         |
| Specification (TS) 3.0.3, TS 3.0.3 was entered at 0820 when both trains of   |
| the Main Steam Line Isolation Valve Sealing System (MSIVSS) were declared    |
| inoperable.  The 'B' MSIVSS had been inoperable since 5/4/01 due to a        |
| malfunctioning flow transmitter with the associated TS, 3.6.1.4 1 entered.   |
| On 5/8/01,  at 0508, a Potential Transformer fuse failure associated with    |
| the 'C' Class 1E 4.16kV bus tripped two of four channels of Loss of Voltage  |
| relay protection for that bus.   The tripped channels provide start          |
| permissives for the 'C' EDG and have actuated to the tripped condition to    |
| provide those permissives.   During subsequent investigation of the extent   |
| and consequences of the fuse failure, it was determined at 0820 hours that   |
| the fuse failure also affected the 'C' Emergency Diesel Generator (EDG)      |
| synchroscope rendering the 'C' EDG inoperable due to its inability to meet   |
| the surveillance requirement of TS 4.8.1.1.2.h.10  Since the 'C' EDG         |
| provides the 1E power to the 'A' MSIV Sealing System both trains of the MSIV |
| Sealing System were considered inoperable and TS 3.0.3 was entered.          |
|                                                                              |
| Investigation into the cause of the fuse failure is ongoing.  With the       |
| exception of the 'A' Control Room Emergency Filtration System, all other     |
| safety-related systems were operable at the time of the event.               |
|                                                                              |

| Multi-center open label clinical study to evaluate the performance of the    |
| Proxima GliaSite RTS in patients with recurrent brain tumors undergoing      |
| surgical resection.                                                          |
|                                                                              |
| In this study, the GliaSite RTS is implanted in the tumor resection bed at   |
| the time of surgery.  Two weeks following surgery, a solution of lotrex and  |
| saline is infused into he balloon catheter in order to deliver the radiation |
| dose.  Following a specified dwell time, the lotrex is removed from the      |
| balloon and the balloon is then surgically removed from the patient's brain. |
| Prior to therapy, radiographic contrast media is infused into the balloon to |
| verify the balloon placement.  This contrast media is removed just prior to  |
| the infusion to the lotrex.  All fluid volumes are tracked to determine the  |
| exact volume of fluid in the balloon at all times.                           |
|                                                                              |
| In the specific treatment plan where the deviation from the written          |
| directive occurred, was prescribed by a Radiation Oncologist and infused     |
| into a balloon by a Nuclear Medicine Physician with a dwell time of 70       |
| hours.                                                                       |
|                                                                              |
| Following the prescribed dwell time the lotrex was removed and an initial    |
| assay of the retrieved lotrex demonstrated a 60% apparent reduction in       |
| retrieved activity as compared to the administered activity.  The reduced    |
| activity measured in the retrieval fluid was to be due to a mixture of       |
| contrast media with the lotrex in the fluid.  By diluting  the retrieved     |
| fluid, to remove attenuation characteristics of the contrast media, the      |
| total administered activity was measured.                                    |
|                                                                              |
| Since the contrast media was causing attenuation of the radioactivity in the |
| retrieved fluid, resulting in a reduction of the Dose Calibrator readings,   |
| it is assumed the radiation dose to the tissue surrounding the balloon was   |
| also reduced.  The absorbed dose to the tissue cannot be determined          |
| accurately due to the uncertainty in the homogeneity of the iodine-125 and   |
| contrast media in the GliaSite RTS during the therapy.  Therefore, the       |
| attenuation characteristics and absorbed energy within the tissue cannot be  |
| accurately modeled.                                                          |
|                                                                              |
| During the investigation of this incident, all steps contained  within the   |
| Henry Ford Hospital and NABTT #9801 Quality Management Programs were         |
| followed.  This incident notification of the patient, physicians and all     |
| attending staff within 4 hours following the retrieval of the lotrex that an |
| apparent discrepancy in the activity retrieved existed.  In addition, all    |
| trash and urine were verified to have been retrained and surveys of these    |
| waste showed negligible readings.  All room surveys also showed no           |
| contamination.   The patient, as well as fluid retrained from the surgical   |
| site and the GliaSite RTS all demonstrated no contamination.  The patient    |
| was not harmed by the event.                                                 |
|                                                                              |
| To prevent contrast contamination during this therapy in the future an       |
| additional flushing of all fluid from the balloon prior to infusion of the   |
| lotrex will be done.                                                         |
|                                                                              |
| The NABTT #9801 study is intended as a Phase 1 device trail rather than a    |
| clinical efficacy trail.                                                     |

| On 05/08/2001,  Unit 2 experienced a automatic Reactor Trip due to low water |
| level in the 2A Steam Generator.  Prior to the reactor trip, Instrument and  |
| Control Technicians were tuning the 2A Main Feed Water Regulating Valve      |
| digital control system. The 2A Main Feed Water Regulating Valve went fully   |
| closed, and the Control Room Staff was unable to reopen the valve.           |
|                                                                              |
| At the same time as the Reactor Trip, the Auxiliary Feed Water System        |
| actuated due to low water level in the 2A Steam Generator.  After the        |
| Reactor Trip all Control Rods Fully inserted into the core, all automatic    |
| systems operated as designed, and no primary to secondary leakage was        |
| detected.                                                                    |
