| |
| Report for LER 50-321/1980-080 On July 6,
| |
| 1980, with the Unit I reactor at 8% power in Hot Standby for llPCI testing, the Operations Department discovered water leaking from the RWCU common return line to the reactor vessel.
| |
| Investigation revealed a crack running along the heat affected zone and turning out into the stainless steel (A312-304) spool piece about one inch.
| |
| A second crack was observed in the middle of the 6"
| |
| spool pie::. about one inch in length at approximately the same position on the pipe.
| |
| The spool piece was removed and replaced with one of the same material.
| |
| The weld prep. and final welds were inspected via dye-penetrant examination.
| |
| No indications were found during D-P' examination.
| |
| Our Arc.hitect/ Engineer recommended performing a
| |
| X-ray examination during our next refueling outage.
| |
| This has been included in our ISI schedule for the Unit I
| |
| rafueling outage.
| |
| A hydrostatic pressure test was O" were performed ct 1.1 times the operating pressure and no leaks observed.
| |
| This is not a repetitive occurrence.
| |
| There c
| |
| was no affect on public health or. saf ety as a result of this i.' c i d e n t.
