SUMMARY
APRIL 1984 UNIT 1 The unit started the month in cold shutdown in continuation of the mid-cycle steam generator-inspection outage.
Plant heatup No. 671 was begun on April 10th, with the. reactor being brought critical at 2312 hours0.0268 days <br />0.642 hours <br />0.00382 weeks <br />8.79716e-4 months <br /> on April 11th..The main generator was tied on line at 0816 hours0.00944 days <br />0.227 hours <br />0.00135 weeks <br />3.10488e-4 months <br /> on April 12th.
The unit attained 100% full power at 1315 hours0.0152 days <br />0.365 hours <br />0.00217 weeks <br />5.003575e-4 months <br /> on April 14th.
At 1612 hours0.0187 days <br />0.448 hours <br />0.00267 weeks <br />6.13366e-4 months <br />, on April 21st, the reactor tripped on high RCS pressure.
The trip was caused by a loss of feedwater which was due to an inadvertent trip of the "A" main feedwater pump.
An I&C technician was in the process of bypassing the axial thrust trip on the pump when he accidentally shorted across two terminals, actuating the pump trip circuit.
A normal trip recovery followed.
The reactor was again brought critical at 2216 hours0.0256 days <br />0.616 hours <br />0.00366 weeks <br />8.43188e-4 months <br /> the same day with the unit being tied on line at 0658 hours0.00762 days <br />0.183 hours <br />0.00109 weeks <br />2.50369e-4 months <br /> on April 22nd.
The unit attained 100%
full power operation at 0740 hours0.00856 days <br />0.206 hours <br />0.00122 weeks <br />2.8157e-4 months <br /> on April 23rd and remained there through the end of the month.

Name of facility:
Arkansas Nuclear One - Unit 1 2.
Scheduled date for next refueling shutdown.
Nnvember 1, 1984 3.
Scheduled date for restart following refueling. January 10, 1985 4.
Will refueling or resumption of operation thereafter require a technical specification change or other license amendment? If answer is yes, what, in general, will there 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)?
Yes, Reload Report and associated proposed Technical Specification change.
5.
Scheduled date(s) for submitting proposed licensing action and supporting information.
September 1, 1984 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.
Yes, the reload analysis will be done using newly developed thermal hydraulic codes.
Babcock & Wilcox will be submitting Topical Reports
- on the new codes for NRC review prior to September 1,1984.
