Greenhorne and O'Mara Consulting Engineers Report:
"Licensee called BRC at 8:20am on 5/24/07 to report (2) Troxler gauges stolen from their temporary work site in Nokomis, FL [corner of SR 681 and US 41]. Both gauges were last seen 5/23/07 around 6 pm and were discovered missing early morning 5/24/07. Gauges were locked and secured inside a steel container (conex box) at the temporary job site. Sarasota County Sheriffs department was notified and is investigating. A police report is expected shortly. One of the Troxler gauges belongs to another licensee at the work site: Hubbard Construction company (see incident # FL-07-084). Both licensees were made aware that the BRC recommends that they offer a reward for information leading to the recovery of the gauges and that they advertise in the newspaper, and/or inform the local TV News regarding the reward offer. NRC and HSER were notified. Investigation will continue."
Both gauges are Troxler Model 3411B (S/N's 20029 and 6127), each containing two (2) sources, i.e., 8 millicuries Cs-137 and 40 millicuries Am-241:Be.
At the time the State of FL was notified, the Sarasota Sheriff's Department was enroute to the scene.
Florida report: #FL-07-083 and FL-07-084.

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOST/STOLEN TROXLER MOISTURE DENSITY GAUGE
Rogers Group Company conducted a test at mile marker 63 on Edward T. Breathitt Parkway. After the test was completed they placed the Troxler 4640-B Moisture Density gauge [S/N 1772], 9 millicuries of Cs-137 [Sealed Source Model No. A-102112], in the back of the bed of truck, did not store it or tie it down, and they drove 3.5 miles South on Edward T. Breathitt Parkway at which time they turned around and drove back to mile marker 63. When they arrived back at mile marker 63 they discovered that the gauge was missing, believe that the gauge had fallen out of the truck while it was being driven. They retraced their route that they had taken and asked several working crews if they had seen the missing gauge. The gauge was not found and the licensee believes that a motorist had stopped and picked up the gauge. The licensee notified the State Police of the missing gauge.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT FROM MINNESOTA - MISSING IODINE-125 SEED
The following event was received via e-mail
"On April 23, 2007, 101 I-125 seeds (10 strands, each strand containing 10 seeds, and one calibrated seed) were received by the Nuclear Medicine Hot Lab and transported from the Nuclear Medicine Hot Lab to Rad Oncology for assay on April 24, 2007. All seeds were accounted for. One strand was dismantled and all 10 seeds were assayed and stored in a lead pig. The area was surveyed at the end of the assay process, and the seeds were maintained under lock until the next morning when they were retrieved for the procedure.
"The following morning the strands were taken to the Operating Room for the procedure. The 10 loose seeds used in the assay were loaded in a Mick Cartridge (a device used for surgery) and transported to the OR.
"After the procedure all seeds implanted, seeds in strands and the cartridge (as a whole and not counting the seeds loaded in it) were accounted for. All strands were stored in a lead pig, and the cartridge was stored in a second pig. The package containing both pigs was transported to Rad Oncology and was kept under lock at all times.
"On May 23, 2007, a re-count of the seeds was completed before sending them to the manufacturer. The calibrated seed and the seeds from the strands were accounted for. The cartridge contained 9 out of the 10 seeds it was supposed to be holding. The seed activity at the time it was missed (5/23/07) was 0.361 mCi.
"The area where the cartridge was loaded and unloaded was surveyed as well as the two units that were used to sterilize the seeds. Surveys of some of the areas where the package was transported are still in progress."

"Unit 1 was making preparations to parallel to the grid on 5/28/07. All busses had been transferred to the Startup power supply (230 KV System). Operations then started a large 12KV motor, Circulating Water pump 1-2. Starting this large motor caused a momentary dip in startup voltage. This voltage dip was sufficient to pick up the undervoltage relay on vital bus G, causing a start of that bus's Emergency Diesel Generator (EDG). The bus remained supplied by the startup power supply, the EDG did not load. This valid start of EDG 1-2 is being reported per 10CFR50.72(b)(3)(iv)(A).
"The EDG was subsequently shut down and returned to it's normal standby condition."
There is nothing unusual or not understood about this event and all systems functioned as required.
The licensee notified the NRC Resident Inspector. |

"On 05/29/2007 at 08:08 am CDT, the Wolf Creek Nuclear Plant Information System (NPIS) was removed from service for a planned computer system upgrade. The system upgrade will result in the SPDS and Emergency Response Data System (ERDS) being inoperable for approximately three weeks.
"Wolf Creek Nuclear Operating Corporation is making this ENS notification pursuant to the criteria of 10 CFR 50.72(b)(3)(xiii). There is no other loss of emergency assessment capability concurrent with the removal of the NPIS from service. Plant personnel entered the appropriate Off-Normal procedure and will obtain local readings for the equipment that is normally monitored by SPDS and NPIS during the plant computer upgrade.
"The Senior NRC Resident has been briefed on this evolution and the planned return to service of the system." |

"On 5/28/07 with Hope Creek in Operating Condition 1 at 100% Reactor power, an electrical transient and loss of 'A' and 'B' reactor feed pumps resulted in lowering reactor water level. Operators inserted a manual reactor scram at 0835 in response to the lowering reactor water level. Reactor water level lowered to (-) 38 inches subsequent to the manual scram, resulting in initiation of High Pressure Coolant Injection (HPCl) and injection to the reactor vessel. The Reactor Core Isolation Cooling (RCIC) system also initiated but tripped. Investigation of the cause of the electrical transient, loss of the 'A' and 'B' RFP's, and trip of the RCIC system are currently in progress.
"Initial review of the event indicates that all other systems operated as expected. Current plant conditions as of 1100 are: Hope Creek is in mode 3 at 715 psig with heat removal to the main condenser via the Main Turbine Bypass valves. All control nods fully inserted on the scram.
"This report also documents a 4 hour report under 10CFR50.72(b)(2)(iv)(A) for valid ECCS initiation and injection to the reactor vessel (RAL 11.3.1)."
The reactor is stable with the water level currently at 17 inches and feedwater being supplied by the 'C' feed pump. No Safeties lifted during the transient. All systems functioned as required except for the trip of the RCIC. The licensee was not in any major technical specification LCO at the time of the trip.
The licensee notified the NRC Resident Inspector. The licensee will also notify the States of NJ and Delaware, and Lower Alloways Creek Township. | |
