| RECEIPT OF A TRU-TEC SERVICES, INC., CONTAINER OF BROMINE-82 THAT APPEARED   |
| TO HAVE BEEN OPENED AND RE-PACKAGED INCORRECTLY DURING TRANSPORT BETWEEN     |
| TEXAS A&M AND ST. CROIX IN THE VIRGIN ISLANDS                                |
|                                                                              |
| On 12/04/00, Tru-Tec Services, Inc., shipped an empty container from their   |
| facility in La Porte, Texas, to Texas A&M via Acme Trucking.  The container  |
| was similar in shape to a propane tank (but taller).  It was lead filled and |
| weighed between 700 and 750 pounds.  It also had a 3-inch by 3-inch cavity   |
| inside and a lid with a T-bar to hold the lid in place.  Texas A&M loaded    |
| the empty container with bromine-82, and the activity of the bromine-82 at   |
| noon on 12/04/00 was 900 millicuries.  The bromine-82 was double             |
| encapsulated (inside three glass ampoules which were also inside a metal     |
| swagelock container with a screw on cap).  After Texas A&M loaded the        |
| container, Acme Trucking transported the container to Federal Express at     |
| Intercontinental Airport in Houston, Texas, on 12/04/00.  Apparently, the    |
| container arrived at a Federal Express hub in Memphis, Tennessee, on         |
| 12/05/00, and it remained there until 12/07/00.  On 12/07/00, the shipment   |
| left Memphis, Tennessee, via Federal Express and arrived in Puerto Rico on   |
| the morning of 12/08/00.  It was then transported by 4 Star Air Cargo to St. |
| Croix in the Virgin Islands.  Tru-Tec Services, Inc., received the container |
| between approximately 1600 and 1630 EST on 12/08/00.                         |
|                                                                              |
| Upon arrival in St. Croix, Tru-Tec personnel discovered a problem with the   |
| container.  It appeared that the container had been opened and put back      |
| together incorrectly.  The container's T-bar was missing, and the lid was    |
| upside-down with the bromine-82 on the outside of the container rather than  |
| shielded on the inside of the container.  The bromine-82 appeared to be      |
| intact.  Smear tests were performed using a GM detector, and there was no    |
| evidence of contamination or of a breech in the double encapsulated          |
| material.  Survey readings with the bromine-82 unshielded on the outside of  |
| the package resulted a dose rate of 6 millirem per hour at a distance of 6   |
| feet.  The bromine-82 is currently under control and in the possession of    |
| the Tru-Tec Services, Inc.                                                   |
|                                                                              |
| The bromine-82 was intended for use in tracer studies at chemical plants,    |
| and it was manufactured at Texas A&M.  It was reported that the half life of |
| bromine-82 is 35 hours, and the estimated activity of the material at noon   |
| on 12/08/00 would have been 140 millicuries.  bromine-82 is a strong gamma   |
| emitter.  The Tru-Tec Services, Inc. main office is located in Delaware.     |
|                                                                              |
| The licensee plans to contact the carriers and plans to attempt to trace its |
| path and discover who came into contact with the container.                  |
|                                                                              |
| (Call the NRC operations officer for licensee contact information.)          |

| At 0320 Unit 2 received indications of a primary leak in containment that    |
| exceeded allowable values in Tech Spec 3.4.6.2. These indications included   |
| containment gas activity alert alarm, Pressurizer level reduction,           |
| Pressurizer spray valve closure and an increase in charging flow. Indicated  |
| charging/letdown mismatch is 7 gpm.  Calculated primary leak rate estimate   |
| based on VCT and Pressurizer level changes was 9.5 gpm at 0400. At 0412 Unit |
| 2 began a plant shutdown at 2% per minute.  This constitutes the initiation  |
| of a plant shutdown required by Tech Specs.  A containment entry is planned  |
| to identify the source of the leak. The entry will be made after the reactor |
| is subcritical.                                                              |

| Date of event: November 21 & 23, 2000 Location of Event; Centralia, WA       |
| ABSTRACT: (where, when, how, why; cause. contributing factors, corrective    |
| actions, consequences, DOH on-site investigation; media attention) The       |
| licensee notified the WA Department of Health, Division of Radiation         |
| Protection, that replacement rods (installed after source rod failures       |
| documented in Washington event reports #WA-00-046 and WA-00-054) had failed  |
| on November 21 and November 22.                                              |
|                                                                              |
| As reported previously, the Ronan Engineering Company Model SA-4 gauging     |
| device (containing up to 74 gigabecquerels of cesium-137 in an Amersham      |
| Model CDC.711M source) is operated by lowering the source at the end of an   |
| approximately six foot source rod into a dry well. The gauge is removed from |
| service by pulling up on the source rod until the source enters the shielded |
| body of the gauge. The source rod was originally constructed in several      |
| screw-together  sections. Failure number 1 (September 13) was the apparent   |
| result of mechanical vibration loosening the upper screw joint until it came |
| apart as the source rod was being lifted. Failure number 2 (October 5) was   |
| presumed to be metal fatigue in that the male threaded portion of the lower  |
| screw joint snapped off from the rod as it was being lifted. Since an exact  |
| replacement rod was no longer available from Ronan, the actual replacement   |
| consisted of two rod sections connected at each joint by a spring-loaded     |
| brass pin and a short manufactured adapter that was tooled for the pin       |
| connector at one end and a threaded male connector at the other.             |
|                                                                              |
| Failure number 3 (November 21) and failure number 4 (November 23) also       |
| occurred while lifting the source rod. In both instances, the lower          |
| pin-connected joint failed apparently as a result of the increased tension   |
| as the source enters the shield overcoming the spring tension on the brass   |
| pin, thus  'popping' the connector loose. After the second failure of this   |
| type, the gauge was taken out of service and the manufacturer requested to   |
| provide an exact replacement rod. The  'old style'  screw-together sections  |
| were installed December 7. The  'new'  pin-connected rods provided for the   |
| other three gauges had not been installed because no problems had occurred.  |
| The licensee plans to replace all four gauges by the end of 2001 when new    |
| process equipment is installed.                                              |
