NRC MONTHLY OPERATING REPORT' OPERATING
SUMMARY
JUNE 1984 UNIT 2 The unit began the month operating at 100% full power.
On June 16, power was reduced to'95% for Moderator Temperature Coefficient (MTC) Testing.
The MTC Test was completed on June 17, and the unit was returned to 100% full power.
Later that day the unit. tripped when a CEA dropped.
On June 18, the unit was returned to power operation but once again tripped on high steam 4
generator level.
The unit was returned to power and reached 100% power on June 20. The unit continued operating at 100% power through the remainder of the month.
Note:
Attached is a revision to the May Monthly Operating Report.
This revision is being made because of a slight change in auxiliary power usage.

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, some proposed software changes to the Core Protection Calculators are being considered.
5.
Scheduled date(s) for submitting proposed licensing action and supporting information.
February, 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.
