SUMMARY
- The plant entered May at 100% power and remained at 100% until approximately 03:00 on 5/27/02, when power was reduced to approximately 95% to allow for troubleshooting of a reactor demand control module. Power was restored to 100% at approximately 06:00 on 5/27/02. The plant remained at full power until approximately 00:30 on 5/31/02, when power was reduced to approximately 90% for planned main turbine control valve testing. Power was restored to 100% at approximately 06:30 on 5/31/02.
