SUMMARY

There were no unplanned losses during the month of October 2016. A control rod adjustment was made and ST-23B was conducted (control rod coupling test) between 10/5/16 03:09 and 15:24. Rx Power was reduced from 78.3% to 68.16, which was the minimum throughout the evolution.

Per INPO 04-004 (Rev. 15), control rod testing is considered exempt energy generation loss. On 10/28/2016, Rx Power was lowered from 72.2%

to 70.8% due to a 1% deviation in A Reactor Water Recirc speed indication. Operators conducted the downpower per Rx Engineering instructions.

Since the downpower was less than 20% Rx Power, it is not counted as a Generation Occurrence. As this speed indication resulted in an unplanned change in Rx Power, the actual losses due to A RWR issue are reported as unplanned energy losses.

SUMMARY

There were no unplanned losses during the month of December 2016. On 12/1/2016 ~ 11:22, a LEFM Correction Factor Calculation was made which led to about a 1.2% change in indicated Rx Power. (Note: LEFM corrections do not result in any change to MW Electric Output.) A control rod adjustment was made on 12/7/2016 between 04:11 and 14:04. This evolution caused a 2.5% change in Rx Power (from 62.2% to 59.7%). Per INPO 04-004 (Rev. 15), control rod testing is considered exempt energy generation loss. The power change as a result of this evolution was also

< 20% RTP and, therefore, will not be reported as a Generation Occurrence.

On December 15th, 2016 at 14:25, with reactor power at approximately 7.7% RCTP, reactor power was increased and 22% RCTP was achieved at 17:30 and the Main Turbine Generator was synchronized back onto the grid. On December 15th, 2016 at 15:30, active Limited Condition for Operation (LCO) ACT 1-16-0265 was entered due to a body to bonnet leak on MSIV AO-203-2D (CR-PNP-2016-10040). On December 16th, 2016 at 16:11 with reactor power at 22% RCTP, a reactor shutdown was initiated and reactor power was reduced. On December 16th, 2016 at 18:38 with reactor power at approximately 11% RCTP, the main turbine was manually tripped and the main generator removed from the grid. On December 16th, 2016 23:42, reactor power was reduced to approximately 5% RCTP and the reactor was manually scrammed in accordance with normal controlled shutdown procedures. Following the repair of MSIV AO-203-2D, on December 22nd, 2016 at 00:32, operators commenced control rod withdrawl for reactor startup and at 08:30, the reactor was declared critical. On December 22nd, 2016 at 20:11, the Main Turbine Generator was synchronized to the grid. On December 23rd, 2016 at 09:30, the reactor attained 100% RCTP. On December 23rd, 2016 at 12:30, operators commenced a reactor downpower to adjust the control rod pattern. On December 23rd, 2016 at 15:12, the reactor was returned to 100% RCTP. The minimum reactor power level achieved during the evolution was 69.3% RCTP. On December 24th, 2016 at 11:00, operators once again commenced a downpower to adjust the control rod pattern. On December 24th, 2016 at 13:43, reactor power was once again returned to 100% RCTP. The minimum reactor power level achieved during the evolution was 70.5%. Reactor power was maintained at 100%RCTP throughout the remainder of the month.

SUMMARY

On 10/14/16 power was reduced in preparation for a planned Control Rod sequence exchange. Lowest power was 67%. Full power was achieved on 10/15/16.

Generation losses from this routine control rod adjustment, and other testing, contributed to INPO's SPEL (Exempt) loss classification.

While at full power on 10/31/16 21:25, a Reactor Recirc Pump tripped resulting in an Unplanned Power Reduction of approximately 77.2%. The lowest power experienced was 22.8%.

Following repairs, the power ascension ramp to 100% power was completed on 11/03/16.

All Control Rods were reported as being inserted 10/01/16 10:17. Following Turbine maintenance, the Reactor was declared critical at 10/07/16 02:50, and the Main Generator was synchronized to the grid at 10/08/16 03:38. 100% power was achieved on 10/10/16 02:47.

SUMMARY

On 10/01/16 the Main Turbine was manually tripped from approximately 15% to begin a planned turbine outage. On 10/08/16 the U2 Main Generator was again synchronized to the grid, and full power was achieved on 10/10/16.

On 10/28/16 from 100%, a scheduled down power for Control Rod pattern adjustment was initiated. The lowest power of 71.4% was seen on 10/29/16, and power was increased to full power later that day.

(Note: Generation losses from this power change, other routine control rod adjustments, and testing are classified as SPEL (exempt losses) for INPO Performance Indicator purposes.)
