"During normal power operations at 100 percent power on Unit 2, both trains of Containment Air Return Fans (CARF) were declared inoperable at 19:28 [EST] on January 9, 2018 due to a common issue with control power fuses. The fuses potentially could not handle the in-rush current upon re-energizing the circuits. This condition resulted in a loss of a reasonable expectation that the Unit 2 Containment Air Return Fans would meet their design safety function and mitigate an accident. This loss of safety function is reportable under 10CFR50.72(b)(3)(v)(D), 8 hour report. The site entered T.S. 3.0.3 at 19:28 and exited at 20:54 when repairs to 2B CARF were completed. 2A CARF repairs are complete. There was no impact on the health and safety of the public or plant personnel. The senior NRC Resident Inspector has been notified."
The licensee verified this problem does not affect unit-1.
* * * RETRACTION AT 0939 EST ON 03/08/2018 FROM JUSTIN BLACK TO TOM KENDZIA * * *
"A subsequent evaluation determined that the fuses for the Containment Air Return Fans (CARFs) would be able to perform their safety function and were operable at the time of discovery. The limiting safety condition for the fuses is the return to power following a Loss of Offsite Power (LOOP). The evaluation determined that the fuses would satisfy their safety function upon re-energizing the circuits if a LOOP occurred and would not impact the ability of the CARFs to perform their safety function. The subject fuses were replaced on January 9, 2018."
The Licensee notified the NRC Senior Resident Inspector.

| Event Text AGREEMENT STATE REPORT - GAUGE SHUTTER STUCK OPEN
"At about 0900 CST, Oklahoma Department of Environmental Quality [OK DEQ] received a report from Martin Marietta Materials Bell-Savoy Plant, located in Kemp, Oklahoma. They reported that a factory technician had discovered on February 27, 2018 that the shutter was stuck open on an Ohmart SH-F1 Gauge, serial number 7117GK. The device reportedly contains a 100 milliCurie (as manufactured, the device is believed to be over ten years old) Cesium source, but no source model number or serial number is known at this time. The company has closed off the area irradiated by the exposed source until the shutter can be repaired. No overexposures to humans are known or suspected. The company recently purchased the plant from another owner, and should have a GLD registration with the state, but does not have one. OK DEQ has not been able to locate a registration for the previous owner. This is a preliminary report based on initial information submitted to us, and will be updated when more information becomes available." |

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

The following report was received from the State of Arkansas via e-mail:
"At approximately 1127 CST on 2/28/2018, the Arkansas Department of Health [ADH] Radioactive Materials Program received a phone call from the licensee stating that during routine shutter tests the gauge shutter handle fell off and the shutter is stuck open. The gauge is a Vega America Corporation (Ohmart) Model A-2102, serial number 6997, originally containing 1.5 Curies [Cesium-137] on 4/30/1968 (calculated current activity approximately 475 milliCuries).
"Discussion with the licensee indicates that the gauge is mounted on a digester, outside of normal employee traffic. It is normally open during operations and is only closed during maintenance of the digester, which is not planned. Cautionary signage is already present. The licensee representative stated that the staff will be made aware of the situation. Licensee maintenance is assessing the situation and will advise the ADH Radioactive Materials program of the plan for handling this situation.
"The State of Arkansas is awaiting a written report from the licensee and final disposition information for the gauge. The State's event number is AR-2018-003." |
