AGREEMENT STATE REPORT - DAMAGED TROXLER

The following was received from the Kansas Department of Health and Environment via email:

"A nuclear density gauge was struck at approximately 0100 [CDT], Thursday, July 16, 2015. At 0132 [CDT], [Kansas Division of Emergency Management] KDEM on duty staff officer, received a call from the Kansas Highway Patrol that a nuclear density gauge had been struck in Wichita. [Kansas Department of Transportation] KDOT was on scene. [KDOT] said the gauge was in use at the time by Cornejo and Sons. The supervisor from Cornejo was on the scene. He said the gauge was completely destroyed. He could see the source plate containing the neutron source and said the source rod was stuck in the car that hit the gauge. [KDEM] had similar incidents in the past and could put the source in 5 gallon bucket of dirt for shielding and transport both sources back to their shop, place in a secure area, and contact Troxler for further instructions. KDOT had a radiation survey instrument on scene and did not detect any unusual readings.

"At that time emergency response personnel at the scene were not letting anyone approach the debris and the source rod. [Personnel at the scene] confirmed that the Cs-137 source was still intact and that Cornejo could transport both sources back to their shop. [The licensee] recovered the sources and were transporting them back to their shop. On the afternoon of July 16, 2015, [Kansas Department of Health and Environment] confirmed that Cornejo had the source rods secured. [The licensee RSO] stated that they contacted Troxler to begin the source return process i.e. pictures of the source rods as well as leak tests."

INTERIM PART 21 REPORT - ACTUATOR FAIL MODE DEVIATION AND POTENTIAL NON-CONSERVATIVE ACTUATOR SIZING

The following information was received via fax:

"Pursuant to 10 CFR 21.21(a)(2), Fisher Controls International LLC ('Fisher') is providing required written interim notification of a deviation or failure to comply in product shipped to the Krsko Nuclear Station ('Krsko') located in Slovenia.

"On July 16, 2015, Fisher became aware of an issue with an actuator fail mode for an 8 [inch] 2052- Control Disc valve, Serial Number 19443837. The affected valve was supplied in a 'Fail Closed' configuration rather than the desired 'Fail Open' configuration. Fisher has corrected the configuration and retested the affected valve at the Krsko site. Krsko has since accepted the valve for installation.

"During the investigation, it was also noted there was an increase in one of the sizing factors for the valve that may have led to a non-conservative actuator sizing for this and other valves provided to this Krsko site. Fisher is currently performing an extent-of-condition review of safety-related rotary orders in order to confirm that correct orientations and actuator sizing were provided. Any identified deficiencies will be reported per the requirements of 10 CFR21.21(b). This review is expected to be completed by October 23, 2015. Additionally, all current safety related rotary orders in-house are being reviewed prior to shipment. This notice affects only rotary valves with Fisher factory mounted actuators.

"Corrective Action CAR 1756 has been opened to document corrective actions taken to prevent reoccurrence.

"Should there be any further questions concerning this matter, please contact Benjamin Ahrens, Manager, Quality by email at Benjamin.Ahrens@Emerson.com or via phone at 641-754-2249."

* * * UPDATE FROM GEORGE BAILINGER (VIA FAX) AT 1634 EDT ON 10/30/15 * * *

As excerpted from the fax:

"Extent of condition investigations into both issues have determined that no additional valve configurations have shipped with these deficiencies."
