AGREEMENT STATE REPORT - LOST MOISTURE GAUGE
The following information was from the State of California via email:
"On 04/04/13, [the licensee] RSO, called RHB [California Radiologic Health Branch] to report a lost gauge. The gauge is a Model 503 DR CPN moisture gauge (S/N H33064926) containing 50 mCi (max) of Americium 241:Be. [The RSO] stated that he placed the gauge in the back of his truck next to the tailgate, then got distracted by a telephone call and started driving from 4181 Brew Master Dr, Suite 4, Ceres, CA, on Crows Landing, Hwy N 99 and then onto Hwy 88 without securing the gauge. He discovered the gauge missing [at 1600 PDT] on 04/03/13, upon arrival at a jobsite. The Ceres Police Department was notified of the lost gauge (case # 213-001653). Licensee was advised to place an advertisement in a local paper/craigslist offering a reward of $4000.00 for the safe return of the gauge. RHB will be investigating the incident and licensee will be cited for the items of non compliance associated with this incident."
California Report: #040413
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.

COOLING WATER MAKEUP PUMP FAILED TO START DURING A SURVEILLANCE TEST
"At 1053 [EDT] on April 3, 2013, during the performance of a surveillance test on the Division 2 Emergency Equipment Cooling Water (EECW) system the EECW system was declared inoperable due to the Division 2 EECW makeup pump failing to start during the surveillance. The EECW system cools various safety related components, including the High Pressure Coolant Injection (HPCI) room cooler.
"A 14 day Limiting Condition for Operation (LCO) was entered for HPCI via [Technical Specification] LCO 3.5.1. Investigation into why the makeup pump did not start is currently in progress.
"This report is being made pursuant to 10 CFR 50.72 (b)(3)(v)(D) as a condition that at the time of discovery could have prevented the fulfillment of a safety function needed to mitigate the consequences of an accident, based on a loss of a single train safety system.
"The NRC Resident Inspector has been notified."
* * * UPDATE FROM BRETT JEBBIA TO VINCE KLCO ON 5/28/13 AT 1613 EDT * * *
"An evaluation of Event 48886 has determined that the Division 2 Emergency Cooling Water (EECW) system was capable of supporting HPCI Room Cooler and HPCI operation for a period of time in excess of that required to perform the required safety functions as assumed in the accident analysis. Therefore, this event is retracted."
The licensee notified the NRC Resident Inspector. Notified the R3DO (Orth).

AUXILIARY BUILDING SPECIAL PARTICULATE IODINE NOBLE GAS MONITOR OUT OF SERVICE
"On April 3, 2013, at 0800 CDT, the Kewaunee Power Station discovered that the Auxiliary Building Special Particulate Iodine Noble Gas 'SPING' Monitor (Mid and hi Range) was Non-Functional due to an external failure. The SPING is used to aid in assessing Emergency Action Levels. The expected out of service time is unknown at this time. Trouble shooting is currently in progress. Work will be performed with high priority.
"Although manual 'grab samples' could be used as a backup, this condition is being reported in accordance with 10CFR50.72(b)(3)(xiii) as an event that results in a major loss of emergency assessment capability (unable to sufficiently identify the upper two emergency action levels for Offsite Radiation conditions).
"The NRC Resident Inspector has been notified."
* * * UPDATE AT 1448 EDT ON 4/03/13 FROM STODOLA TO HUFFMAN * * *
The Particulate Iodine Noble Gas 'SPING' Monitor was recalibrated and returned to service at 1257 CDT on 4/03/13.

AGREEMENT STATE REPORT INVOLVING DIFFICULTY IN RETRACTING A FIXED GAUGE SOURCE
The following information was provided by the State of Kansas via fax:
"This letter is to inform [the Kansas Department of Health & Environment] that yesterday afternoon [on 4/3/13, the RSO] had attempted to move a source from its drywell into its source holder to prepare for maintenance activities in the vessel. The source seemed to be stuck in the drywell. Because the cable restraining the source does not allow the shutter to close until it completely retracted, the shutter would not close. Later last night, after consulting with VEGA Americas and [the company] on-site engineers, [the RSO] attempted again to remove the source and it was free. The source has been safely stored in its holder. There were no reportable personnel exposures. Because of the position of this source 8 feet inside a large vessel with 5 [inch] steel walls, it is shielded at least as well as inside its holder.
"The shutter in question is on an Ohmart/VEGA model SHLM-CR3 source holder S/N 19077664, containing 2 Ci of Cs-137 in a model A2102 sealed source S/N 0587CO.
"The source is located at [the company facility] in EI Dorado, KS . . .. It is approximately 140 feet above the ground. Operations and maintenance personnel were notified of the issue. A wipe sample was collected to check for gross leakage. None was indicated.
"What [the RSO] believe[s] caused this situation was the combination of two (2) things. The reactor was being cooled with nitrogen over the past few days. It has also been raining and snowing. [The RSO] believe[s] water was drawn into the well during cooling and the nitrogen cooled that area of the reactor enough to freeze the water in the well. Ice was present on the cable as it was pulled out. Because the reactor was sufficiently cooled, the nitrogen purge was reduced, thus allowing the reactor to warm slightly by 8 PM when [the RSO] tried again.
"[The RSO] feel[s] that this was not, in fact, a shutter issue, but an operational issue which [the RSO] will be cognizant of in the future. [The RSO] will simply make sure the internal temperature of this vessel is above 40 degrees F before attempting to remove the top source. Normally it is over 500 Degrees, so water intrusion is not an issue. Again, the source was always in a safe position. At no time were personnel exposed to any reportable levels of radiation."
