SUMMARY

Month: April, 1986 Catawba Unit I began April at 100% power but the unit tripped on April 19 during the replacement of a reactor coolanL flow transmitter. The unit returned to service on April 21.

Power escalation was delayed to perform Reactor Coolant system leakage calculations, and to place feedwater i

heaters in service, but the unit reached full power again on April 22.
