CGS budget squeezed by new security mandates; 60 non-security jobs to be cut
The 60 jobs to be eliminated by June 30 at Columbia Generating Station represent about 5% of the company's workforce. About half of the job cuts will be through planned retirements, normal attrition and vacancies that will not be filled. The rest will be based on operational requirements, employee performance, versatility and length of service. The security force will not be affected. The cuts are part of the company's approach to cutting $5-million in costs during next fiscal year. More than $7-million in previously unanticipated security costs are now expected to be incurred in coming year due to new federal requirements.

Operating summary - July 6, 2003 through October 4, 2003
The period began with Columbia Generating Station at approximately 78 percent power, due to an out of service condensate booster pump. The plant reinstalled the pump and raised power to 100 percent on July 15. Operators maintained the plant at essentially 100 percent power for the remainder of the period.

Examples of post-9/11 security changes at Columbia
Security activities at Columbia Generating Station continue to escalate. The first wave of federal mandates was implemented a year ago, resulting in a new concrete barrier that surrounds the plant, a new checkpoint to search vehicles and the hiring of additional security guards. Energy Northwest and other commercial nuclear plant licensees in the US also must redesign their defense plans to prepare for an even greater threat and standardize their security force training and qualifications. The changes must be in place by October 2004. [Source: Chris Mulick et al (Tri-City Herald staff writers), "Security constant since Sept. 11", Tri-City Herald, September 10, 2003]

Summary of Plant Ops Status - March 23 - July 5, 2003
At the start of the period, operators maintained the plant at 100 percent power. On May 3, 2003, operators initiated a plant shutdown in response to a significant condenser leak. Energy Northwest completed the shutdown and entered Forced Outage FO-03- 02 on May 4. Operators maintained the plant in a shutdown condition and entered Refueling Outage 16 on May 10. Plant startup initiated on July 2, when operators placed the reactor mode switch in operational Mode 2. The plant refueling outage officially ended on June 27 when, at about 20 percent reactor power, operators synchronized the generator to the main power grid. Over the next few days operators increased plant power through the planned power assention profile. On June 30, while at 79 percent power, the main turbine tripped on a main transformer differential current signal. The turbine trip caused an automatic reactor scram. Energy Northwest effected repairs, including rewiring similar circuits on potentially vulnerable transformers, and operators placed the plant in Mode 2 on July 2. The following day, the operators synchronized the plant to the grid at about 24 percent power. Operators increased plant power to 78 percent, where it remained until the end of the inspection period on July 5, 2003. Energy Northwest restricted plant power to 78 percent until final installation of a repaired condensate booster pump. [Source: Columbia-2 - reactor trip after turbine trip (cause unknown)
