The state’s only commercial nuclear power plant’s return to operation, scheduled for Friday, will be delayed until next week to perform extensive tests.
The testing is needed because of a change in instrument settings designed to increase the total power output, the Washington Public Power Supply System said Thursday.
Plant No. 2 began its annual maintenance and refueling outage April 22.
“These few extra days provide us the opportunity to wrap up maintenance tasks and complete necessary paperwork during a time when power from Plant 2 is not critical to meeting the region’s needs,” said Rod Webring, acting general manager of Plant No. 2.
The supply system delivers power to the Bonneville Power Administration.
