SUMMARY

OF OPERATING EXPERIENCE Docket No. 301-Unit Name Point Beach, Unit 2 Date December 9, 1985 l

Completed By C. W.

Krause Telephone 414/277-2001 At the beginning of-the period, the unit was shut down undergoing j

a scheduled refueling and maintenance outage.

The outage was completed and on November 22, the reactor was taken critical.

On November 24, the generator was placed on line.

The following day, the generator was taken off line temporarily for overspeed testing.

At the end of the period, power output was limited to 88% due to standard post-refueling new fuel conditioning, t

Steam generator eddy _ current testing during the outage revealed that 10 tubes of the "A" steam generator and 44 tubes of the "B" steam generator required plugging.

LER-85-003 was written to document the circumstances of the condition.

i As mentioned in the October monthly report, a failed fuel rod was i

found in two fuel assemblies (L56 and L59).

It is believed that

- fuel. failure was' caused by fuel rod vibration resulting in fretting wear at the fuel rod grid supports.

The fuel rod vibration was caused by water jetting through several core baffle plate joint openings impinging upon the failed fuel rods.

A visual inspection of the lower core support plate revealed pieces of fuel pellets which had come from the failed fuel rods.

Actions were taken to remove loose fuel pieces.

LER 85-004 has been written for this incident.

l

- Safety-related maintenance included a modification to the incore

[

detector system that changed the cover gas from carbon. dioxide to helium in an effort to minimize detector tube corrosion.

Also, additional. manual reactor trip pushbuttons were installed and main control board cabling was rerouted to' provide train separation for manual reactor trip.

Reactor' trip bypass breaker indications l

were also installed on the main control board.

Other safety-related maintenance included the' replacement of four split pins and the repair of a' loose instrument guide tube.found at the bottom nozzle of a fuel assembly.
