The following information was obtained from the state of Tennessee via fax:
"On June 4, 2012 Eastman Chemical Company contacted the [Tennessee] Division of Radiological Health concerning an incident that had just occurred. A shutter on a fixed level gauge was difficult to operate and could not be completely closed. In an attempt to close the shutter, a viscous polymer material which had leaked onto the top part of the gauge was removed. However, removal of the polymer still did not allow for complete closing of the shutter. Surveys have confirmed that radiation levels around the gauge are normal. The vessel manway is posted and procedures are in place to prevent entry into the vessel prior to the gauge being repaired or replaced."
The level gauge contained 173 mCi of Cs-137. No personnel overexposures were reported.
Tennessee Event: TN-12-148
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 FLORIDA AGREEMENT STATE REPORT - POTENTIAL OVEREXPOSURE
The following information was obtained from the state of Florida via email:
"First quarter 2012 whole body dosimeter badge for a nuclear med tech indicated a 10.5 Rem dose. Badge was recounted and the dose remained the same. Dose is not confirmed by ancillary ring dosimeters. Ring dosimeters indicate a typical 100 mR/month. Because the ring dosimeters do not confirm the badge dose, the consulting health physicist does not think this is a valid dose and the med tech is still working. Florida is investigating."
The isotope used by the medical technician is Tc-99, 30 mCi.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text DAMAGED TROXLER MOISTURE DENSITY GAUGE
The gauge operator finished with a density reading and left the Troxler device at the measurement area when he was storing his tools in his truck. When he was returning to the measurement area, an end-loader drove over the Troxler, destroying the hand operating pad. At the time of the accident, the source was retracted into the shield. Immediately after the accident, the operator covered the gauge with shielding and established a boundary zone. No overexposures or contaminations are expected as the sources were retracted into the shielded position.
The Troxler is a model 3430 which contains 40 mCi of Am-241 and 8 mCi of Cs-137. The licensee is conferring with Troxler to determine whether the gauge will be repaired or returned for disposal.

"At 1757 EDT on 6/12/12, Brunswick Nuclear Plant experienced a fault on the Emergency Response Facility Information System (ERFIS) uninterruptible power supply (UPS) electrical bus 'A'. This resulted in a loss of site Safety Parameter Display System (SPDS), Emergency Response Data System (ERDS) and Plant Process Computer (PPC) for both Unit 1 and Unit 2. The cause of the fault is not yet understood and under investigation. No other major plant effects occurred and no major plant evolutions are planned.
"During the loss of SPDS, the emergency response capability of that system was lost to the site. During the loss of ERDS, the automatic data transfer feature of that system was lost for transmissions to the NRC, however manual data transfer is still available. During the loss of the PPC, automatic core thermal power averaging and automatic core thermal limit monitoring was lost. Manual calculations are available for these functions.
"Unit 1 SPDS was restored to the Emergency Operations Facility (EOF) at 1949 EDT. Unit 2 SPDS was restored to the EOF at 2030 EDT. ERDS and PPC remain unavailable with troubleshooting in progress. Both units reduced power to 98% as a conservative measure.
"The NRC Resident Inspector has been notified."
* * * UPDATE FROM JOHN MILLER TO JOE O'HARA AT 0257 ON 6/14/12 * * *
"The Unit 1 and 2 ERFIS, SPDS, and ERDS functions were restored by approximately 0630 hours on June 13, 2012, after an alternate power supply configuration was established. In addition, the PPC functions were restored by approximately 1630. Compensatory actions will be maintained until the UPS 'A' bus is restored and returned to normal configuration. The Brunswick Emergency Response Organization (ERO) Site Emergency Coordinator and Emergency Response Manager have been briefed on the compensatory actions in place.
"Investigation of this condition will be documented in the corrective action program in Condition Report (CR) 542704.
"The NRC Resident Inspector was notified."

"At 1343 [EDT] on 6/13/12 an Unusual Event was declared due to a reported Ammonium Hydroxide spill in a storeroom on the first floor of the Administration Building. At 1357 [EDT] the State of NH was notified and at 1401 the State of Massachusetts was notified of the Unusual Event using the State Notification Fact Sheet. The delay to the State of Massachusetts notification was due to issues with the dedicated phone system.
"At 1422 the NRC was notified of the Unusual Event using the Event Notification Worksheet. This initial notification reported a one gallon spill of Ammonium Hydroxide. Additionally there were no reported injuries and no impact to plant equipment.
"Further investigation revealed that the spill amount is 1-2 pints out of a 1 gallon container and the initial report of no injuries was validated. The concentration of the Ammonium Hydroxide is 25.5%. The spill was confined to a small area of the store room on the first floor of the Administration Building. The spill had no impact on plant equipment used for normal operation. Initial cleanup by plant personnel is complete and external services have been notified to complete the final spill cleanup.
"Seabrook Station is terminating the Unusual Event. Seabrook Station will continue to investigate and resolve the issues with the dedicated state notification phone system. Currently we have a troubleshooting team which has verified backup communications via the commercial phone lines is available."
The Unusual Event was terminated at 1730 EDT.

| Event Text SAFETY EQUIPMENT FAILURE - CRITICALITY AIR HORNS NOT TESTED FOR AUDIBILITY
"While reviewing Maintenance Work Package 'Performance of the C-335 Annual CMS Surveillance' from April 28, 2012 an error was identified. Procedure 'C-335 CMS Maintenance And Testing' requires an audibility check if the as-found values for the regulator air pressure drift feeding the Criticality Accident Alarm System (CMS) air horns is >?12 psig. However, an audibility check was not performed as required at six locations all on the cell floor of the process building that were discovered to be out-of-tolerance. All air pressure regulators were adjusted to within acceptable-as-left tolerances prior to the system being made operable on April 28.
"Without the audibility testing being performed, the audibility of the C-335 CMS was questionable prior to the April testing. On June 13, 2012, a work package was developed to recreate the pressures encountered on April 28 and to test the audibility of the CMS. Subsequent testing has shown that three of the CMS horns fed by out-of-tolerance pressure regulators may not have provided the required sound levels necessary for audibility in those areas. This is failure of safety equipment required by TSR 2.4.4.2.
"This event is reportable as a 24 hour event in accordance with 10 CFR 76.120(c)(2), 'An event in which equipment is disabled or fails to function as designed when: (i) the equipment is required by a TSR to prevent releases, prevent exposures to radiation and radioactive materials exceeding specified limits, mitigate the consequences of an accident, or restore this facility to a pre-established safe condition after an accident; (ii) the equipment is required by a TSR to be available and operable and either should have been operating or should have operated on demand; and (iii) no redundant equipment is available and operable to perform the required safety function.'
"The NRC Resident Inspector has been notified of this event.

"On 6/13/12 at 1700 CDT, it was determined that valve 2-FCV-73-81 (HPCI steam line warm-up valve) was not capable of performing its intended primary containment isolation valve function. This determination was made during performance of a prompt determination of operability for a steam leak from a missing adapter on a Furmanite injection port in the valve packing area. To meet Technical Specification (TS) 3.6.1.3 action requirements for an inoperable primary containment isolation valve, 2-FCV-73-2 (HPCI inboard steam isolation valve) was closed at 1745 hrs., rendering U2 HPCI inoperable. As a result TS 3.5.1 actions were entered.
"This incident is reportable as an 8-hour ENS notification under 10CFR 50.72 (b)(3)(v)(B) and (D) as 'any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to remove residual heat and mitigate the consequences of an accident.'
"It also requires a 60 day written report in accordance with 10CFR 50.73(a)(2)(v)(B) and (D).
