"At 2229 [CDT] on 05-02-2016, River Bend Station declared the High Pressure Core Spray system INOPERABLE in accordance with Technical Specification 3.8.9, Condition E (Declare High Pressure Core Spray System and Standby Service Water System Pump 2C inoperable immediately) due to Division 1 Control Room Air Conditioning System HVK-CHL1C being INOPERABLE due to a trip of the chiller on high inboard bearing temperature.
"Actions taken to exit the LCO: Alternated divisions of Control Room Air Conditioning System to Division 2 HVK-CHL1D in service and Division 1 HVK-CHL1A in standby."
The licensee notified the NRC Resident Inspector.
* * * RETRACTION ON 6/22/16 AT 1137 EDT FROM JACK MCCOY TO DONG PARK * * *
"Supplement: An operability evaluation has been performed based on system operating procedures in place at the time of this event, and on calculations regarding heat-up rates of the spaces served by the main control room air conditioning system. Operating procedures already in place on May 2 specified the operator actions required to restore the air conditioning system to service following the unanticipated trip of a chiller. The normal shift complement was on duty at the time of the event, and could have provided an adequate number of operators to accomplish this task. The operability evaluation made no new assumptions regarding availability of operators. The manual actions to be performed for the start of an alternate chiller following a trip of an in-service chiller system have been determined to require 2.15 hours, based on ANSI 58.8 guidance. (ANSI/ANS 58.8, Time Response Design Criteria for Nuclear Safety Related Operator Actions, provides the industry guidance In this regard.)
"Calculations of building heat-up rates have demonstrated that the loss of the air conditioning system can be sustained for 19 hours before temperatures in the rooms containing the Division 3 electrical equipment that support operability of the HPCS system exceed their maximum allowable ambient value.
"Based on the conclusions of the operability evaluation, the trip of the 'C' HVK chiller on May 2 had no actual adverse effect on the ability of the electrical distribution systems in the main control building to support the safety function of the HPCS system. Event Notification No. 51899 is hereby withdrawn."
The licensee has notified the NRC Resident Inspector. Notified R4DO (Rollins). |

"On Monday June 13, 2016, the licensee's radiation safety officer contacted the Agency [Illinois Emergency Management Agency] to advise that a seed localization procedure utilizing a radioactive source was not going to be completed as planned. An I-125 seed had been implanted on June 9, 2016 to mark an area of the breast for subsequent examination and surgical explantation on June 13, 2016. However, the patient experienced a stroke during the interim days and the planned surgery for explantation aborted. Given the patient's condition it was determined that the risk associated with surgery to the patient was greater than the risk associated with not performing the seed retrieval. Initial estimates of the effective whole body dose are 3.7 Rem and dose to the breast 73 Rad. No permanent functional damage to the organ/tissue is expected as a result of the inability to remove the source. If the patient's condition improves and the opportunity arises, the seed may still be explanted at a much later date."

This was reported from the State of Alabama via facsimile:
"On June 13, 2016, the Radiation Safety Officer for Nucor Steel in Decatur, Alabama notified the Alabama Office of Radiation Control in regards to a piece discovered in scrap metal received via railcar. The piece appears to be a retaining ring approximately the diameter of a dime. The piece is reading over 5,000 mRad/hr at contact using a Ludlum model 15 survey meter. The piece has been secured in a building within the site boundary and away from employees. The licensee is continuing to research where and when the piece arrived onsite. The [Alabama] Office of Radiation Control plans to meet with site personnel on June 16, 2016. As of today, [6/14/16] 1235 CDT, this incident remains open until further investigation can be completed."

"On June 16, 2016, [representatives from the Alabama] Office of Radiation Control visited the site to conduct measurements and spectrum analysis. The retaining ring read 13.5 mR/hr at contact, 3.6 mR/hr at one foot, and 0.5 mR/hr at three feet with a Fluke 451P #2644, calibrated 12/10/15. Spectrum analysis using a Thermo IdentiFINDER revealed the isotope to be Co-56. This was confirmed through the Joint Analysis Center Collaborative Information System.
"As of today [06/17/16], 1025 CDT, this incident remains open until disposal options have been completed."

The New Jersey Department of Environmental Protection was informed that a vehicle containing a Troxler gauge Model 3411B, S/N 19870, was involved in an accident. New Jersey Department of Environmental Protection responded to the scene. The gauge was damaged, but radiation levels around the gauge were normal. The licensee's Radiation Safety Officer took possession of the gauge.
* * * UPDATE AT 0944 EDT ON 6/17/16 FROM KAREN FLANIGAN TO MARK ABRAMOVITZ * * *
The following report was received via e-mail:
"Local HAZMAT notified the New Jersey Department of Environmental Protection (NJDEP) that a vehicle that was towed from the scene of a motor vehicle accident was found to contain a portable [nuclear] gauge. NJDEP staff responded to the towing yard and identified the device as a Troxler 3411-B moisture-density gauge belonging to New Jersey licensee Atlantic Engineering Laboratories, Inc. The source rod was fully retracted, but the sliding block on the bottom of the gauge was stuck open. The exposure rate at the opening in the plate was 5.2 mR/hr. The licensee's RSO came to the site, closed the sliding block, performed a leak test, and returned the device to its Type A package. The RSO took possession of the gauge for transport to the licensee's licensed storage location."

The following was received from the State of Washington via email:
"[A common carrier] lost 252 IsoRay Cesium-131 brachytherapy seeds intended for four patient implants. On Friday, 6/9/2016, radioactive materials licensee, IsoRay (WN-L0213-1) sent four orders of cesium-131 brachytherapy seeds. The four orders contained a total of 252 seeds at a total air kerma activity level of 522.8 U. The total apparent activity is approximately 1 Ci (the actual activity is between 1 - 2 Ci). The absorbed dose from the 252 seeds would be approximately 52,280 rad (522.8 Gray). Early Tuesday morning, 6/14/2016, the Memphis hub of [the common carrier] informed IsoRay that they were unable to locate these packages, and they would not be delivered on time as contracted. They were scanned in and out at both the Pasco and Spokane airports. The Spokane flight to Memphis arrived, but [the common carrier] could not locate them. IsoRay notified the state of the loss of radioactive material that same day.
"On 6/15/2016, IsoRay notified the state that [the common carrier had] found the missing shipments and are returning them to IsoRay. They were not delivered to the intended physicians. There are no details yet on how they became misplaced. IsoRay has scheduled a senior management meeting with [the common carrier's] Priority Alert team to trouble shoot the missing shipments.
"This incident is one of several incidents in which [the common carrier] played a role within the last 4 months."

"At 0841 [CDT] an automatic turbine trip occurred, resulting in an automatic reactor protective system (RPS) actuation due to loss of turbine load. The source of the turbine trip was from the distributed control system (DCS) and is being investigated via a root cause analysis. This was an uncomplicated trip, all systems responded as expected post trip, and the reactor trip recovery procedure was entered at 0852 [CDT]."
The plant is stable in Mode 3 with a normal electrical line up and decay heat removal via steam dumps to the condenser.
