SUMMARY
OCTOBER 1984 UNIT 2 The unit began the month at reduced power operation because of secondary chemistry problems.
On October 1st the unit was returned to 100% full power and remained there through October 26th.
On October 26th, the unit tripped due to a dropped rod and remained shut down for repairs of the drive unit.
The unit was returned to power on October 31st but tripped that same day due to ASI out of limits during power escalation.
The unit was returned to power and finished the month at 30% power.

Schedulad date for next refueling shutdown.
April 1985 3.
Scheduled date for restart following refueling. July 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)?
Some software changes to the Core Protection Calculators are planned to be made during the upcoming refueling.
These changes may result in some technical specification changes.
5.
Scheduled date(s) for submitting proposed licensing action and supporting information.
By February 1, 1985 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.
Burnable poison rods will be used in reload fuel.
