LOSS OF COMMUNICATIONS DUE TO PLANNED MAINTENANCE
"A planned maintenance evolution at the Oyster Creek Nuclear Generating Station has removed the dedicated phone line between Emergency Response Facilities and the NARS [Nuclear Accident Reporting System] line from service and will be rendered non-functional during the course of the work activities. Expected out of service time is approximately 82 hours from 0900 [EDT] 6/23/14 to 1900 [EDT] 6/26/14.
"If an emergency is declared requiring the use of emergency communication phone circuits a proceduralized alternative method will be used.
"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) for planned maintenance that impacts the emergency communications capability. An update will be provided when the dedicated phone line between Emergency Response Facilities and the NARS line has been restored to normal operation."
The licensee has notified the NRC Resident Inspector.

EMERGENCY DIESEL GENERATOR AUTO START DUE TO DEGRADED BUS VOLTAGE SIGNAL
"At 1107 [CDT] on 6/23/14, Safeguards Bus 15 received a degraded voltage signal that resulted in the bus load shed and the automatic start of the D1 Emergency Diesel Generator (EDG). Bus 15 re-energized to normal voltage after the source breaker from D1 [EDG] automatically closed. This event is reportable under 10 CFR 50.72(b)(3)(iv)(A) for valid actuation of the D1 EDG.
"The initiating condition appears to be a failure of the automatic voltage tap changer on the 10-Bank transformer which affected voltage to the normal offsite power supply to the 1R transformer and Safeguards Bus 15.
"Currently Bus 15 is powered from offsite via the CT-11 transformer and D1 [EDG] has been shutdown.
"When Bus 15 power supply was transferred from D1 [EDG] to CT-11 transformer, a lockout was received on D1 [EDG] due to reverse power. Unit 1 is in TS [Technical Specification] 3.8.1 Condition D for one path inoperable and one EDG inoperable.
"At no time during the event were the health and safety of the public challenged. The redundant AC power supply train (Bus 16 and D2 EDG) remained operable and Bus 16 remained powered from offsite power.
"The Senior Resident Inspector has been notified."
TS 3.8.1 Condition D requires that the one inoperable offsite power path or the D1 EDG be returned to operable status by 2334 CDT or be in Mode 3 in 6 hours. Unit 2 is not affected by this issue.

REPORTABLE SMALL OIL SPILL INTO U.S. WATERS
"On 06/23/2014 at approximately 1540 [CDT], it was reported that an oil sheen was visible in the fore bay. Upon further investigation it was determined that a high cold water channel level had caused diesel fuel oil to wash free from an oil drain device from the channel diesel fire pump into the fore bay. This oil spill is reportable to the EPA (National Response Center) under 40CFR112. Notification to the National Response Center was made at 1551 [CDT]. Notification number is 1086840.
"A total of 1 to 2 gallons were reported to enter US waters. The source of leak into the fore bay and cold water channel has been stopped. All reportable oil spillage has been contained in the fore bay (considered US waters).
"Additional notifications have been made to Alabama Emergency Management."
The licensee has notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - DAMAGED FIXED GAUGE FOUND IN SCRAP METAL SHIPMENT
The following information was received by facsimile from the State of Oregon:
"Event Description: OR Radiation Protection Services [RPS] was notified by facsimile on June 24, 2014 at 0813 [PDT], by Schnitzer Steel Industries, 12005 N. Burgard Way [Portland, Oregon] of one cesium-137 fixed gauge received in a truckload of scrap from Idaho that triggered their site entry detectors. RPS personnel investigated, found the gauge housing to be severely crushed, shutter damaged and partially open. One side of housing is split but compressed together. Identification plate still attached and mostly legible and given as follows: Manufacturer: Texas Nuclear; Model: 5197; Gauge housing serial number: B7951; Source: Cesium-137; Activity: Currently 65 mCi according to Thermo Fisher Scientific.
"Gauge is being stored in secured metal bin in restricted and remote area on company site. Highest exposure reading at bin surface measured at 1.48 mR/hour. Schnitzer personnel reported 60,000 microR/hour (60 mR/hour) at approximately 4 inches from split side of gauge housing surface when first discovered. Schnitzer personnel (one person) used shovel and 4 foot steel rod with hook to move gauge from truck to storage bin on June 23rd. Estimated dose to company person from reconstruction of gauge move is 1.50 mrem based on a 6/25/14 exposure measurement. No other company employees received a dose from this device and RPS personnel did not receive any appreciable dose.
"RPS personnel took contamination wipes of gauge housing and found no evidence of exterior contamination after analysis.
"The manufacturer, now Thermo Fisher Scientific, was contacted and found the gauge was originally sold to a Martell, California company, Wheelabrator Martell, Inc., on August 23, 1996. Thermo added the last contact for leak test services was December, 1999. RPS is currently investigating further to trace gauge history since 1999 as well as location in Idaho where truck originated. The gauge will not be returned to the manufacturer according to Thermo and classified as waste. A waste broker will be contacted by Schnitzer for packaging and disposal. RPS will be monitoring this process."
Oregon State Incident: OR-14-0028.

State of Oregon provided clarification of source activity and exposure estimate.

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.
