NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE Docket No.
50-266 Unit Name Point Beach Unit 1 Date June 6, 1983 Completed By C. W. Fay Phone 414-277-2811 Unit 1 operated at approximately 371 MWe net throughout the period with no major load reductions.
The primary-to-secondary leakage remains stable at less than ten gallons per day.
On May 16 at approximately 1405 hours0.0163 days <br />0.39 hours <br />0.00232 weeks <br />5.346025e-4 months <br />, contractor personnel accidentally spilled ten gallons of water, slightly contaminated from the rinsing of respirators.
The spill was isolated on a
(
15 ft. by 15 ft. area outside the Unit 1 facade, and cleaned up.
The NRC was notified via red phone.
On May 21 at 2336 hours0.027 days <br />0.649 hours <br />0.00386 weeks <br />8.88848e-4 months <br />, Unit 1 boric acid line to the blender became blocked restricting boric acid flow to the volume control tank.
The heat trace circuits were adjusted higher and the flow path was restored to operability at 0425 hours0.00492 days <br />0.118 hours <br />7.027116e-4 weeks <br />1.617125e-4 months <br /> on May 22.
The circuits were returned to normal and have been operating with no problems since.
On May 23 at 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br />, the 3D emergency diesel generator experienced a fast start pickup of bus 2A05 when personnel opened the door to 2A05 potential transformer inside the switchgear panel which resulted in an open circuit.
This event required reporting to the NRC via red phone.
On May 26 at approximately 1130 hours0.0131 days <br />0.314 hours <br />0.00187 weeks <br />4.29965e-4 months <br />, Unit 1 "A" reactor coolant i
pump was experiencing oscillating leakage rates past the No. 2 j
seal.
The leakage returned to normal by 1316 hours0.0152 days <br />0.366 hours <br />0.00218 weeks <br />5.00738e-4 months <br /> and is currently being closely monitored.
Other safety-related maintenance completed during the period included the changeout of reactor trip relay 1RT-6B and repairs to a packing leak on the "A" steam generator steam line vent valve.

NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE Docket No.
50-301 Unit Name Point Beach Unit 2 Date June 6, 1983 Completed By C. W. Fay Phone 414-277-2811 Unit 2 was shut down during the entire report period as it completed the tenth week of the scheduled 14-week refueling and steam generator sleeving outage.
Outage-related work included the installation of replacement tube bundles for "A",
"B",
"C",
and "D" moisture-separator-reheaters, the installation of replace-ment feedwater heaters 4A and 4B, the turbine overhaul, the installation of pressurizer relief valve header supports, refueling calibrations, the changeout and testing of NBFD reactor protection system relays, repairs to various diaphragm valves in the chemical and volume control system, cleaning of the incore thimbles, cleaning of the existing Nos. 5A and 5B feedwater heaters, and the changeout of radiation monitors 2Rll/R12.
Inspection of optimized fuel assembly ZD3 has identified at least nine rodlets with through-clad defects.
These defects are all at the first (lowest) grid elevation.
At other locations, not necessarily at grid elevations, through-wall penetrations and zircaloy hydriding were noted.
This damage appeared to have been initiated from the inside of the rod.
It is believed that these through-wall penetrations were the result of secondary zircaloy hydriding caused by the inleakage of reactor coolant via the fretting induced penetrat. ions at the first grid elevation.
ZD3 is one of our optimized fuel assemblies in Unit 2 for testing purposes.
The other three assemblies, as well as the 69 reload standard assemblies, have been wet and dry sipped for possible leakage.
No other assemblies had indications of leakage.
In addition to sipping, the other three optimized fuel assemblies were visually inspected with no anomalies noted.
Additionally, a sampling of rods were measured for breakaway forces and visually inspected to add further assurance of no similar degradation of the clad.
No abnormal readings were recorded.
A 24-hour notice has been filed with the NRC.
The sleeving work scheduled during this outage has been completed in "B" steam generator and is approximately 59% complete in "A"
