On 09/05/2013 at 1016, control element assembly (CEA) #27 dropped to the bottom of the core while performing surveillance test procedure O-29-2.

Reactor power stabilized at 91%. An abnormal operating procedure was entered and attempts to restore the CEA to the correct level were not successful. At 1207 reactor power was reduced in preparation for a reactor shutdown. This down power met the criteria for the NRC Unplanned Power Change per 7000 Critical Hours performance indicator.

The cause of the dropped CEA was determined to be a ground due to degraded insulation. The ground was located at the coil stack connection at the reactor head. The coil stack was replaced, other connections inspected, and all control element drive mechanisms were electrically tested (meggered) during the shutdown and prior to startup to verify no other ground fault conditions existed. Resistance checks of individual coils were performed and all were verified to be within 10% of the mean.

SUMMARY

Diablo Canyon Unit 2 began the month of July in Mode 1 (Power Operation) at approximately 100 percent reactor power. On July 10th, an apparent electrical flashover of a Unit 2 main bank transformer lightning arrestor resulted in a reactor trip. Preliminary investigation suggests that the electrical disturbance was experienced during routine "hot washing" an insulator. On July 13th, 2013, Unit 2 was returned to critical and entered Mode 1 (power operation). On July 15th, 2013, Unit 2 returned to full power and it remained there for the rest of the month.

A generator protection relay trip setpoint was programmed incorrectly during the 2012 refueling outage. LER 2013-002 was submitted on this event. Reprogramming of the generator protection relay was performed to remove the trip function.

SUMMARY

The unit operated at full power from the beginning of the month until July 23, 2013 at 1419, when the main generator tripped during positive VAR testing. The generator trip caused a turbine trip and reactor trip from full power. The reactor criticality was achieved on July 27, 2013 at 2017 following generator protection relay reprogramming to remove the trip function. The unit was brought on-line on July 28, 2013 at 1032. Full power operations resumed on July 29, 2013 at 0500 and continued through the end of the month.

At the time, the plant was operating at 100% Rated Core Thermal Power. The scram occurred shortly after the Turbine Stress Evaluator (TSE) was turned on. I C turned the TSE on and the TSE-INFL alarm in the control room cleared. LOAD-LTD was noted to be dropping after the TSE was turned on.

Approximately one minute later, LOAD-ACTUAL was noted to be dropping and the reactor scrammed due to a turbine trip. The shift immediately entered EP-2 for Reactor Scram, the Reactor Scram ONEP, and Turbine Trip ONEP.

RCIC initiated and injected during the transient.

However, no Level 2 alarms were received.

Reactor levels were verified and RCIC was subsequently secured. All other systems operated as expected. The plant was stabilized with pressure control on the bypass valves, and level controlled on the startup level control valve.

SUMMARY

The plant continues to operate at EPU power. However a performance test has not been performed and a new Reference Unit Power (RUP) has not been determined. Losses during the month were corrected to the RUP using a ratio of the previous license power (3898) to the current license power (4408).

SUMMARY

The month started with the unit online and the reactor critical at 98.0% RTP due to main condenser pressures reaching the main turbine design back pressure limit as a result of: extreme environmental conditions, high dry bulb and wet bulb air temperatures. The unit returned to 100% RTP on 7/1/13 at 0147 One (1) planned power change greater than 15% occurred in July 2013.

A power decrease of approximately 26.2% (100% to 73.8%) occurred on 7/26/2013 at 2000 for Main Condenser waterbox cycling. Power was stabilized at 73.8% RCTP on 7/27/2013 at 0057. Power ascension started on 7/27/2013 at 0508. The unit returned to 100% on 7/27/2013 at 1050.

This is a planned power reduction IAW NEI 99-02.

Zero (0) unplanned power changes greater than 15% occurred in July 2013.

The month ended with the unit online and the reactor critical at 99.8% RTP.

The SRVs were not challenged by any over pressurization events or transients that would have required the valves to respond automatically.

SUMMARY

The month started with the unit online and the reactor critical at 93.1% RTP due to main condenser pressures reaching the main turbine design back pressure limit as a result of: extreme environmental conditions, high dry bulb and wet bulb air temperatures. The unit returned to 100% RTP on 9/3/13 at 2222.

One (1) planned power change greater than 15% occurred in September 2013.

A power decrease of approximately 24% (100% to 76%) occurred on 9/7/2013 at 0005 for main turbine valve testing. Power was stabilized at 76% RCTP on 9/7/2013 at 0303. Power ascension started on 9/7/2013 at 1401. The unit returned to 100% on 9/7/2013 at 1839. This is a planned power reduction IAW NEI 99-02.

One (1) unplanned power change greater than 15% occurred in September 2013.

A planned power decrease of approximately 12% (100% to 88%) occurred on 9/19/2013 at 2000 for planned control rod pattern adjustments.

Power was stabilized at 88% RTP but there was no power ascension. A power decrease of approximately 28% (88% to 60%) occurred on 9/19/2013 at 2142 due to the A recirc pump speed controller failing to 0% demand reducing the pump to minimum speed. Power was stabilized at 60% RCTP on 9/20/2013 at 0304. Power ascension started on 9/20/2013 at 1643. The unit returned to 100% on 9/21/2013 at 0542. This is an unplanned power reduction and is not excluded IAW NEI 99-02.

The month ended with the unit online and the reactor critical at 99.9% RTP The SRVs were not challenged by any over pressurization events or transients that would have required the valves to respond automatically.

SUMMARY

At the beginning of the month, reactor power was 75% due to the inability to start Reactor Feed Pump 'A'. On September 8th, 2013 at 14:03, a controlled shutdown commenced to allow repairs of leaks in the condenser bay. At 21:38, all control rods were fully inserted. Repairs in the condenser bay were completed and reactor startup commenced on September 15th, 2013 at 00:00. At 05:13, the reactor was made critical and at 19:27 the main generator was synchronized to the grid. Reactor power achieved approximately 75% on September 17th, 2013 at 07:40. At this time, reactor power was still limited due to RFP 'A'. A temporary modification that routed new cables to RFP 'A' was completed and the pump was placed into service. On September 17th, 2013 at 07:40, power ascension once again commenced and full reactor power was achieved at 13:00.

On September 18th, 2013 at 10:04, a reactor downpower commenced to adjust the control rod pattern. The minimum power achieved during this evolution was 78%. At 14:40, reactor power once again achieved 100%. Reactor power was maintained at 100% throughout the remainder of the month.

The reactor was maintained at approximately 15%

power. 07/21/13 23:10 performed Auto Synchronization and loading of Main Generator.

Note: The shutdown was planned less than 10 days in advanced, but more than 72 hrs in advance. This is not a Forced Loss Event because this shutdown plan was implemented to address the initial condition associated with the cause for the FLE reduction of 23% on 7/16/13.

SUMMARY

There was one power reduction greater than 20%. The Unplanned Power reduction was initiated on 7/16/13. The reduction from 96%to 74%

power was required to reduce Turbine vibration experienced due to Turbine Control Valve position. The Turbine was taken off-line on July 21, after reducing power to 15%, to perform maintenance on the Turbine Control Valve servo valve that caused the intial reduction to 74%. The Reactor was maintained at approximately 15% power while the Turbine was off line. The Generator was put on line on 7/21/13, and the Reactor returned to full power on 7/24/13. There were no other power reductions greater than 20% this month.

Breaker closed: 09/23/13 23:17 Return to full power: 09/27/13 07:47

SUMMARY

The one power reduction greater than 20% in the month of September, was for a planned Control Rod Sequence Exchange. On 09/06/13, the power reduction began from 100%. Reactor Power reached as low as 53.7% and was returned to 99.8% power on 9/8/13.

There was one Unit shutdown in September, but there are 2 Reactor Shutdown entries impacting this occurrence, to accurately account for criticality time periods. The power reduction for scheduled shutdown to correct cooling water leaking into the Drywell, and for Main Turbine blade replacements, began at 09/13/13 22:00 from 100%.

The Generator Breaker was opened 09/14/13 02:48 when the Reactor was at 15.5%. The Reactor was taken Sub-Critical by means of an Unplanned Manual Scram from 14% power at 09/14/13 03:30.

Following the completion of the scheduled maintenance, during reactor startup. the Reactor was declared Critical at 09/22/13 22:02. Then, progressing through reactor start-up activities (re-ranging of IRM's), the Reactor was declared sub-critical at 09/22/13 23:13 (all rods not in, but also not critical during Reactor start-up). The Reactor was then declared critical at 09/23/13 00:06, and ramp-up activities continued. The generator was put on line 9/23/13 23:17. Full power was achieved at 09/27/13 07:47.
