| Event Text AGREEMENT STATE REPORT - LEAKING GENERALLY LICENSED SOURCES
The following was received from the state of Colorado via email:
"On or after February 05, 2014, while working on a license renewal action, the Colorado Radiation Program was informed by the licensee that it had three (3) generally licensed electron capture detectors (ECDs), containing ~15-18 mCi of Ni-63 (each), that [leak tests] indicated contamination in excess of regulatory limits. The devices were determined to be manufactured by Hewlett-Packard and Agilent Technologies (model number verification is pending).
"The licensee reported that upon discovery, the devices were contained to minimize potential contamination spread. The area where gauges were used/handled was surveyed and determined to be free of contamination. The licensee indicated that the manufacturer was notified and the devices have been returned to the manufacturer for disposal.
"Further investigation by the Colorado Radiation Program is pending." |

"While investigating a Unit 1 high pressure coolant injection (HPCI) room instrument sump level high alarm, condensation was observed dripping out around the HPCI turbine shaft gland seals. A steady stream of water was also observed coming out of the governor end gland seal along with a slight leak coming from the coupling end. Observation revealed that leakage through the 'closed' steam admission valve (1E41-F001) was apparently resulting in water accumulation in the HPCI turbine. A blown fuse that prevented the associated HPCI exhaust drain pot from draining in conjunction with the leakage by the steam admission valve was determined to be sufficient to impact HPCI operability. Required actions were taken in accordance with the Technical Specifications.
"Efforts are underway to determine the actions needed to restore the HPCI system to operable status."
The licensee has notified the NRC Resident Inspector.
* * * UPDATE FROM JOHN SELLERS TO CHARLES TEAL AT 0154 EDT ON 5/2/14 * * *
"HPCI has been restored to an Operable but degraded nonconforming condition. Fuses replaced and automatic functions restored. Leakage confirmed to not be excessive for this condition. Compensatory actions established. Restoration time 2345 EDT 5/1/14."
The licensee will notify the NRC Resident Inspector.

"An employee with a foreign body in his left eye reported to the on-site dispensary this morning. The plant nurse administered first aid and then released the employee to an off-site medical facility for further evaluation. A whole body survey of the employee in his plant clothing was performed. The maximum amount of contamination present was on the employee's boots, 370,667 dpm/100cm2. Prior to leaving the Restricted Area, the employee removed all plant clothing, changed into his personal clothing, and was whole body frisked out of the plant. The employee was free of contamination upon release."

| Event Text PART 21 REPORT - CHECK VALVES WITH MISSING JAM NUTS
The following is a synopsis of information received via facsimile from Flowserve:
Jam nuts were found to be missing on size 4, pressure class 600, normally open, in-line check valves per Flowserve drawing no. 07-45546-01. The valves are used in saturated steam service and must close with a reverse flow of less than 7000 lbs/hr steam at 95 and 1085 psig. The valve operating parts are identified as safety related.
These valves were supplied to both Diablo Canyon and Sequoyah nuclear power plants. Flowserve recommends that all in-service valves be inspected for proper torque and that dual thread staking be provided per revised Flowserve drawings. |

"This notification is being made due to a loss of emergency assessment capability in accordance with 10 CFR 50.72(b)(3)(xiii). At 1920 (PDT), on 05/02/2014, PRM-RE-18, Reactor Building Stack Monitor - Intermediate Range Detector, failed downscale. PRM-RE-1A and PRM-RE-1C, the Reactor Building Stack Monitor - Low and High Range Detectors, both remain operable and fully functional. Compensatory measures are being implemented per plant procedures at this time.

"At 1209 CDT on 3 May 2014, Dresden Unit 2 automatically scrammed on a Generator-Turbine Load Mismatch signal following a main generator trip. All rods inserted to their full in positions.
"All systems operated as expected. Reactor vessel inventory and pressure are being maintained in automatic.
"The cause of the scram was due to a main generator trip that occurred during a voltage regulator channel transfer. Troubleshooting is in progress to determine the exact cause of the generator trip.
"This condition is being reported pursuant to 10CFR50.72(b)(2)(iv)(B), any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical."
The plant is in a normal shutdown electrical lineup. Main feedwater is being used to maintain reactor vessel level and decay heat is being removed by the main condenser via the turbine bypass valves. There was no impact on Unit 3 which remains stable at 100 percent power.
