SUMMARY
OF OPERATING EXPERIENCE DOCKET NO.
50/395 UNIT V. C. SUMMER I DATE 06/11/86 COMPLETED BY G. A. LOIGNON TELEPHONE (803) 345-5209 On May 1, 1986, the V. C. Summer Nuclear Station, Unit 1, was operating at approximately 100 percent power.
On May 31, 1986, at 1026 hours0.0119 days <br />0.285 hours <br />0.0017 weeks <br />3.90393e-4 months <br />, the plant tripped from 100 percent power.
While testing was in progress on one power range detector channel, a separate channel was inadvertently placed in test causing a reactor trip. Subsequent to the trip, condensate system perturbations created water hammers which resulted in damage to feed heaters and condensate system piping supports.
