OPERATIONS
SUMMARY
Fort Calhoun Station operated at essentially 100% power until March 15, 1985, when a scheduled maintenance outage was initiated to repair Control Element Drive Mechanism No. 22 (CEDM 22).
A complete containment inspec-tion was conducted with no major problems identified. All planned mainte-nance was completed and the Station returned to service on March 17.
Power escalation to 100% was completed on March 19 after a chemistry hold at 30% power.
The initial auxiliary operator-nuclear class has started using the training program proposed for INP0 accreditation. Two Senior Reactor Operator candidates successfully passed the requalification exam
' administered by the NRC. This exam was a retake of an exam given in November, 1984.
Chemistry and Radiation Protection monitored performance of the secondary system chemistry during the outage with a special sampling program.
Pre-liminary results indicate that the power reduction did result in a purge of certain impurities from the' steam generators.
No safety valve or PORV challenges or failures occurred.

This modification provided for changes to the toxic gas monitoring. system which will effect the automatic function of the control room ventilation system. These modifications merely increase _ the margin of safety for the.
control room operators in the event of a toxic gas release accident, and have no adverse effect on the safety-analysis.

TRAINING
. During March,1985,' development of performance-based training programs-for non-licensed operators continued.
Training for new operators is
._in progress.
Licensed operator requalification training included plant systems, emergency. procedures and Technical Specifications. A hot license training class began on March 25, 1985.
