| AGREEMENT STATE REPORT REGARDING RECOVERY OF FIVE ABANDONED CESIUM-137 |
| SOURCES IN SAN DIEGO, CALIFORNIA. |
| |
| The following text is a portion of a document that was E-mailed to the NRC |
| operations center by the California Radiation Control Program: |
| |
| "On the evening of 4/3, the Hazardous Incident Response Team (HIRT) here in |
| San Diego responded to a situation involving an abandoned radiation source |
| at a Vons parking lot located at 620 Dennery Rd., SD 92154. A Vons clerk |
| reported that a person told him that a bomb was left in the parking lot. |
| When the clerk returned with his manager, the man was gone. A black case |
| was left in a shopping cart, which the clerk opened [...]. No bomb was |
| present, but there was a lead container containing a radiation source. The |
| maximum reading the HIRT obtained at the scene was 12 mRem/hr at the surface |
| of the lead container; HIRT took possession of the source." |
| |
| "[Jon Dillon (DHS-RHB)] was contacted the next morning to assist in |
| evaluating this source of radiation. There was an old label on the outside |
| of the pig that indicated Nuclear Associates as the manufacturer and that |
| there was a total activity of 320 mCi of Cs-137 in what appeared to be five |
| sources. No date was indicated, and the To: line only stated Tijuana. |
| Using a portable MCA, [it was determined] that the sources inside the pig |
| were in fact Cs-137. Using [a] Victoreen 450P, [the] measured a range of |
| exposures [was determined to be] from 10 mR/hr to 28 mR/hr at various |
| positions around the lead pig. In order to identify the sources, [the pig |
| was] carefully opened[, and] five small cylindrical sources [could be seen] |
| recessed in the lead pig. The sources were about 1/8" in diameter, and only |
| about a 1/8" of the length was visible. [It was estimated] that these |
| sources were 3/4" to 1" in length. The Victoreen quickly jumped up to 5.8 |
| R/hr, so [the pig was] quickly closed [...] to return the dose down to the |
| mR range. [The pig was] re-sealed [...] with duct tape and the original |
| metal band[, and then the container was] temporarily placed [...] back in |
| the 5 gallon pail that the HIRT team used to recover the source. The |
| container was then appropriately labeled for storage." |
| |
| "Dave Cammell, who is with [the] HIRT, contacted Nuclear Associates directly |
| regarding this source, and they are sending a package to ship this source |
| back to them. At this time, [it is not known] what the sources were used |
| for. By the physical condition of the label and the tape on the pig, [it |
| was estimated] that this is 15-20 years old, if not more. The [sources] |
| will be secured in the HIRT laboratory until [the shipping materials are |
| received] from Nuclear Associates. There has been no media attention thus |
| far." |
| |
| Law enforcement investigation revealed that this incident was not malicious |
| in nature. |

| STOLEN HUMBOLDT NUCLEAR GAUGE |
| |
| The device was stolen from job site in Valrico, Fl. from a truck after the |
| chain had been cut. The theft was reported to the police department and a |
| reward will be offered by the licensee. The device was a Humboldt model |
| 5001 serial #1287 containing Cs-137/Am-241(8/40 millicuries). |

| AGREEMENT STATE REPORT INVOLVING A MISSING KRYPTON-85 SOURCE |
| |
| The following event was E-mailed to the Headquarters Operation Center. |
| |
| |
| The licensee reported the loss of an approximately 147 millicurie Kr-85 |
| source (originally 300 millicuries in 1989). The source, an Amersham model |
| KAC.D3, serial number 7341-BK, was mounted in a Data Measurements |
| Corporation source holder model BCL-1. The source assembly was supposed to |
| have been removed from a Data Measurements Corporation Paper Weight Basis |
| Profiler that was being decommissioned in late 1999. A wooden box, labeled |
| as containing the source assembly, was transferred to the licensee's new RSO |
| in 2000 and dutifully inventoried until March 2001. Based on survey |
| measurements, the new RSO became suspicious of the wooden box and discovered |
| upon opening it that it contained the detector assembly rather than the |
| source assembly. A search of the site failed to locate the source. The |
| licensee believes that the source was most likely left on the Paper Weight |
| Basis Profiler and recycled as scrap metal. Alternatively, it could have |
| been discarded into waste sent to the landfill. No records for the |
| decommissioning of the Profiler have been found and the individual who |
| performed the decommissioning is no longer employed by the licensee. |
| |
| Disposition/recovery: Presumed to be irretrievably lost. |

| LEAKAGE DISCOVERED ON "B" HOT REACTOR COOLANT SYSTEM (RCS) HOT LEG |
| INSTRUMENT NOZZLE CONNECTION. |
| |
| A maintenance supervisor reported that there was leakage on a pipe to nozzle |
| connection on line I-3/4-RC-126. After further investigation this line has |
| been determined to be the "B" RCS Hot Leg instrument nozzle connection for |
| differential pressure (D/P) transmitter PDT-1121D. PDT-1121D measures the |
| D/P across "B" Steam Generator. This D/P is used as input to the "D" |
| channel Reactor Protection System low flow trip. A chemistry sample confirms |
| boric acid and active iodine. Leakage was reported to be indeterminate |
| i.e., no drops per hour could be quantified. This problem will be corrected |
| before going above 190 degrees F. An LER will be issued. |
| |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| BOTH LOW PRESSURE COOLANT INJECTION (LPCI) PATHS TEMPORARILY INOPERABLE |
| |
| Procedure inadequacies for venting RHR System using Ops Manual B.08.01.03-05 |
| resulted in Tech Spec LCO(s) 3.5.A declaring both LPCI Injection Paths |
| inoperable (72 Hour LCO) and Tech Spec 3.5.C for one Division of |
| Containment Spray and Cooling inoperable (7 Day LCO) NOT entered. Contrary |
| to Ops Procedure #2145 RHR System Discharge Venting these LCO(s) should be |
| entered when RHR is vented. Notifications are being made because a vent |
| valve was opened which made both LPCI Injection Paths inoperable. This |
| condition at the time of discovery could have prevented the fulfillment of |
| the safety function or system that is needed for Residual Heat Capacity. |
| The vent valve is closed and verified closed. The RHR System is Operable |
| at this time. |
| |
| The licensee notified the NRC resident inspector. |
