Event Notification Report for March 21, 2014

SHIELD BUILDING VENT GAS RAD MONITORS OUT OF SERVICE FOR PLANNED MAINTENANCE

"At 1330 CDT on March 21, 2014, 1R-22 and 2R-22, Shield Building Vent Gas Radiation Monitors will be removed from service for planned preventative maintenance and therefore [will be] nonfunctional. These monitors have no compensatory measure that will allow timely classification of two Emergency Action Levels (EALs); NUE (Notification of Unusual Event) and Alert classifications when out of service. They are also used for offsite dose projection calculations. This will result in a Loss of Emergency Assessment Capability while 1R-22 and 2R-22 are out of service. This is a reportable condition in accordance with 10 CFR 50.72(b)(3)(xiii).

"Unit 1 and Unit 2 Shield Building Ventilation Stacks are also monitored by high range monitors, 1R-50 and 2R-50, which are used for the same purpose in Site Area or General Emergency classifications. 1R-50 and 2R-50 are being monitored and are indicating normal values. There are no radioactive leaks that will impact the Shield Buildings as evidenced by normal readings on 1(2)R-22 prior to their removal from service. Preventative maintenance (belt inspections) is expected to last approximately 1 hour. Maintenance will not result in the unplanned release of radioactivity to the environment and will not adversely affect the safe operation of the plant or health and safety of the public.

"The licensee has notified the NRC Resident Inspector."

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA WITH STUCK SOURCE

The following Ohio Bureau of Radiation Protection report was received via facsimile:

"The [Ohio] Bureau of Radiation Protection [BRP] was notified by the licensee's corporate RSO [Radiation Safety Officer] at 1505 [EDT] on 3/21/2014, about an incident involving a stuck radiography source. The incident took place at 0430 on 3/21/2014. Crew members were performing radiography in a boiler penthouse in Aberdeen, Ohio, when a magnetic stand fell over and crimped the source guide tube while the source was still out. Crew members called the RSO at their Woodlawn, Ohio [location], who instructed them to survey and post the area and control access until he arrived. The Woodlawn RSO arrived at the site around 0900, shielded the source and was able to bend the guide tube so the source could be retracted back into the camera. The source was safely [positioned] back into the camera around 0945 on 3/21/14. Because licensee personnel wear Instadose dosimetry badges by Mirion Technologies, the Woodlawn RSO was able to determine that the exposure he received from this source retrieval activity was 159 mRem. The licensee understands they are responsible to provide a written report to the BRP within 30 days."

The radiography device is a QSA 880 Delta camera with a 27 Ci Ir192 source.

The licensee has notified the NRC Resident Inspector.

PART 21 - SBM SELECTOR SWITCHES CONTACT ASSEMBLY UNPLANNED MANUFACTURING CHANGE

The following is an excerpt from a fax received from Unified Controls International (UCI):

"...there was a significant manufacturing process change to the General Electric SBM series switches in 2009. The high resistance across switch contacts in the GE SBM switches could lead to a failure of the switch to change state when required. Concerns have been raised regarding tin plated movable contacts used for make or break service and in use without protective lubrication. UCI is not capable to complete an evaluation of the affect that this change may have on in storage SBM switches or already installed SBM switches that were provided to the customers on the purchase orders listed in section [below]. UCI does not know the storage conditions, in service environmental conditions or in service cycling rates of the switches or how the each of these items may affect the change in contact resistance. Each affected customer needs to evaluate their in storage and in service switches and determine if the change in contact material could possibly create a safety hazard and effect the ability of the switches to perform in their safety related application."
