AUTOMATIC REACTOR SCRAM ON LOSS OF FEEDWATER
"The Perry Power Plant experienced a reactor scram during a shift of non-essential vital power supply to the alternate source. Feedwater was lost resulting in receiving a valid level 3 and level 2 signal. High Pressure Core Spray and Reactor Core Isolation Cooling started and injected. Reactor level and pressure have been stabilized to required bands. The motor feed pump has been started and is controlling level. High Pressure Core Spray and Reactor Core Isolation Cooling have been returned to standby."
During the scram, all rods fully inserted into the core. Decay heat is being removed via the steam dumps to the condenser. The electrical grid is stable and supplying plant loads. An emergency diesel generator started, as designed, as a result of the level 2 signal but did not load. No safety valves lifted as a result of the transient. The cause of the loss of feedwater is under investigation.
The licensee will be notifying the State of Ohio and Perry Township and has notified the NRC Resident Inspector.
* * * UPDATE FROM DOUG SHORTER TO HOWIE CROUCH AT 0933 EDT ON 10/20/14 * * *
"The plant is currently in Mode 3, stable with cooldown and depressurization to Mode 4 in progress. Level control is being provided by the motor feedwater pump. Troubleshooting of the cause of the scram and loss of feed water is on-going.
"The initial notification identified 10CFR50.72(b)(3)(iv)(A), 'Specified System Actuation', as a reporting criteria. The specific system that actuated was not provided. As a result of receiving a reactor vessel water level 2 signal a containment/BOP isolation signal was received. All systems isolated as required and the plant is restoring isolated systems in accordance with procedure."
The licensee will be notifying the State of Ohio and Perry Township and has notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE RETRACTION FAILURE
The following information was received via facsimile:
"On October 20, 2014, the Agency [Texas Department of State Health Services] received notice that there had been a radiography source retraction failure at a temporary field site. A pipe had fallen from a stand onto the guide tube, causing a crimp. The source was retrieved by squeezing the crimp with pliers several times, allowing retraction. The individual performing the retrieval received 198 mR according to a pocket dosimeter. The camera was an INC IR-100 (sn 6832) with an Ir-192 source at 44 Ci (sn W644 ). Additional information will be supplied as it is received in accordance with SA-300."
This event occurred at a field site in Encinal, Texas.

BOTH SECONDARY CONTAINMENT AIRLOCK DOORS OPEN SIMULTANEOUSLY
"At 1353 EDT on 10/20/2014, both Reactor Building Airlock doors at NMP1 were opened simultaneously for a few seconds. This results in a momentary loss of Secondary Containment operability (TS 3.4.3). The doors were closed and operability was restored.
"Secondary Containment being inoperable is an 8 hour notification per 10CFR50.73(b)(3)(v)(C), 'any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to control the release of radioactive material.'
"The condition has been entered into the station's corrective action program and the NRC Resident Inspector was notified."
