SUMMARY
OF OPERATING EXPERIENCE UNIT 1 During the reporting period the unit continued in cold shutdown.for the feedwater nozzle repair per NRC Bulletin #79-13.
On January 21 the outage was extended for the repair of 1A charging pump and on January 24 for the repair of 1B RCP seal.
The unit ended the month in cold shutdown.
UNIT 2 Unit 2 entered the reporting period shutdown for the continuation of feedcater nozzle repair per NRC Bulletin 179-13.
The unit was made critical on January 19 at 1250 hours0.0145 days <br />0.347 hours <br />0.00207 weeks <br />4.75625e-4 months <br /> and was synchronized to the grid on January 20 at 0007 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.
On January 24 at 0741 hours0.00858 days <br />0.206 hours <br />0.00123 weeks <br />2.819505e-4 months <br /> a reactor trip occurred caused by a failure of 2A rod drive MG sets causing an overcurrent condition.
The unit was'made critical at 2055 hours0.0238 days <br />0.571 hours <br />0.0034 weeks <br />7.819275e-4 months <br />.
At 2338 hours0.0271 days <br />0.649 hours <br />0.00387 weeks <br />8.89609e-4 months <br /> a turbine trip / reactor trip occurred on low steam generator level in coincident with steam flow / feed flow mismatch.
(While opening turbine stop valves, a steam, flow spike caused a low level coincident with steam flow / feed flow mismatch reactor trip.)
On January 25 at 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> the unit was made critical ana was synchronizeu to tne grid at 0326 hours0.00377 days <br />0.0906 hours <br />5.390212e-4 weeks <br />1.24043e-4 months <br />.
Yne unit was on line for the remainder of the month and ended the reporting period on-line at a power level of 1044 MWe (98% reactor power).

REFUELING INFORMATION REQUEST Questions:
1.
Name of facility.
2.
Scheduled date for next refueling shutdown.
3.
Scheduled date for restart following. refueling.
4.
Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?
If answer is yes, uhat, in general, will these be?
If answer is no, has the reload fuel design and core
. configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59) ?
If no such review has taken place, when is it scheduled?
5.
Scheduled date (s) for submitting proposed licensing action and supporting information.
6.
Important licensing considerations associated with refueling, e.g.,
new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures.
7.
The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool.
8.
The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested or is planned, in. number of fuel assemblics.
9.
The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present lim...ma -,~ d,.
