"C" boiler feed pump had been inoperable since January 5, 1978. LCO 4.3.2 requires two boiler feed pumps to be operable during power ope ra tion. Controlled shutdown was begun followed by a manual scram at 2% reactor power.

Repairs to the feed pumps are in progress.

  • The 1986 date is based on the understanding that spent fuel discharged during the term of the Three Party Agreement will be shipped to the Idaho National Engineering Laboratory for storage by DOE at the Idaho Chemical Processing Plant (ICPP). The storage capacity has evidently been sized to accomodate fuel which is expected to be discharged during the eight year period covered by the Three Party Agreement.
