| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT- STOLEN TROXLER MOISTURE DENSITY GAUGE
According to the Radiation Safety Officer, the operator was at a Kinko's store making copies. The Troxler gauge was locked in a case which was locked and chained to the truck in the parking lot. The chain was cut and the gauge was stolen. The licensee will offer a reward. The theft has been reported to the local police department. The incident has been assigned to the Miami Inspection Office for investigation.
The gauge is a Troxler model 3430, serial number 34898, containing 40 mCi of Am-241/Be and 8 mCi of Cs-137.
Florida Incident Number FL10-007.

"[The] gauge [was] found on 2/15/10 in Miami, FL. The gauge will be operationally checked and leak tested. This office [state] will take no further action on this incident."
Notified R1DO (Jackson), FSME Day EO(McIntosh), and ILTAB(Pearson).
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

| Event Text AGREEMENT STATE REPORT - DAMAGED NUCLEAR DENSITY GAUGE
The following report was received via e-mail:
"At 1310 [PST] on February 11, 2010, the C.Y. Geotech Radiation Safety Officer [RSO] reported that one of the nuclear density gauges (CPN, MC-1DRP, MD90905316 containing 10 milliCurie of Cesium 137 and 50 milliCurie of Americium-241:Be) had been run over by a truck at a construction site. Los Angeles County Radiation Management responded to the scene and found that although the source rod was broken and the plastic case was broken into pieces, the Cesium 137 and the Americium-241:Be sources were still in the shielded body of the device and were intact. There was no contamination. The highest dose rate on the body of the device housing the sources was 9 mR/hr and at one foot was 0.9 mR/hr. The gauge was placed into 2 plastic bags and was placed into the transportation case. The licensee will deliver the gauge to Maurer Technical Services (a licensed CPN representative) who will then ship the gauge to CPN for disposal. [The RSO] reported the gauge user walked about 10 feet away from the gauge to report his test results to a job supervisor and this is when the gauge was run over. The RHB-Brea office will cite the licensee for failure to maintain adequate control over the gauge. The licensee has been instructed they need to provide [California Radiation Control Program] with a report within 30 days as required by regulation. The licensee states they will retrain all of the gauge users regarding the control of the gauge to avoid a similar incident in the future.

PART 21 GROUP (EMAI)
| Event Text INTERIM REPORT CONCERNING AN ISSUE IN SUMP BLOCKAGE GENERIC TESTS
Westinghouse is evaluating an identified inconsistency between test assumptions and the test rig configurations used for Generic Safety Issue (GSI) 191, "Assessment of Debris Accumulation on PWR Sump Performance," testing. Specifically, this issue is related to jet impingement zone-of-influence (ZOI) tests and it applies to testing done for coatings and insulation.
Prior to discovery of the inconsistency, Westinghouse provided letters to the utilities to summarize the testing, analyze the test results, and propose acceptable ZOIs to support resolution of the ZOI aspect of GSI-191. The ZOI tests assumed the smallest diameter in the nozzle producing the jet to be at the nozzle. Westinghouse discovered however, that the inner diameter of an upstream component was smaller than the nozzle. This inconsistency may have resulted in undersized ZOIs being proposed in the letters.
Westinghouse has not yet concluded its determination as to whether there is a defect as defined by 10 CFR 21.
Westinghouse has been working with the Pressurized Water Reactors Owners Group and the NRC NRR Safety Issues Resolution Branch to resolve general test protocol issues and establish methods to evaluate the test results in terms of ZOIs.
* * * UPDATE ON 2/16/2010 * * *
Corrected the title of GSI-191 above and removed incorrect reference to NUREG/CR-6874 since it is not related to the Part 21. |

"This is an eight hour report per 10 CFR 50.72 (b)(3)(xiii). Calvert Cliffs will be implementing a scheduled modification to upgrade the microwave radio system to improve reliability of the system at the Emergency Operations Facility (EOF), State, and County facilities.
"This work will require that the microwave radio system at the EOF be removed for a period of approximately 4 to 6 hours. During this time, the following systems will be impacted for the duration of the upgrade:
"1. The plant's {e.g., Control Room, Technical Support Center (TSC), Simulator} Dedicated Offsite Agency telephones will be out of service. (EOF's system will continue to function)
"2. 800 MHz desk set radios at the EOF only will be out of service.
"3. 153.44 MHz frequency at the EOF only will be out of service. (backup for MEMA and MDE)
"4. MIDAS Terminal (Meteorological Data) located in the Dose Assessment Office at the EOF will be out of service.
"5. TSC Computer data transfer to the EOF only will be out of service.
"Once the upgrade starts the systems (listed above) can be returned to service within the first 2 hours. After the 2 hour timeframe, the upgrade must continue until completed.
"Should an emergency be declared during this period, the Control Room will continue to have the capability to make the notification to the offsite agencies using the direct line for the appropriate agencies. The emergency preparedness communications procedure provides a chart listing the communication devices available and the order in which the process is to be implemented. MIDAS (Meteorological Data) will continue to be operational at the site and can be obtained by contacting the Control Room or TSC. The ERPIPs also provide a backup process and the instructions necessary for the EOF Dose Assessment Office to obtain Meteorological Data. Plant data can be obtained from the CR or TSC and will continue to be downloaded from the plant computer to the ERO SharePoint site.
"All work associated with this microwave radio system upgrade will be performed in an expeditious manner consistent with the goal of minimizing unavailability of the systems listed above. A test of all systems will be performed at the completion of the upgrade.
"All EOF responders and Control Room personnel have been briefed on this work and expected contingent actions.
"This job will start on Wednesday, February 17, 2010 at approximately 7:00 am. We anticipate that all work will be completed by 5:00 pm on the same day, including testing of the system. We will provide a notification update upon completion of the job."
