New Legislation Proposed For Nuclear Safety 144
mdsolar writes "Recent problems at the Vermont Yankee nuclear power plant have spurred Congresspeople from Vermont, Massachusetts, and New Hampshire to introduce legislation that would allow State governors to request independent safety reviews of nuclear power plants. The reviews would exclude NRC employees who usually work on that plant and include non-NRC reviewers. This review model is based on one that found problems at Maine Yankee before it closed. Problems at Vermont Yankee have included a cooling tower collapse, a SCRAM caused by an un-greased valve, and failure of a safety system during the SCRAM. The plant is coming off of heightened review after shipping nuclear material with insufficient shielding. The plant's application for a 20 year license extension is also currently under review."

They boast of 90% up-times because of their quick refueling, but with reduced staff, how can they manage to both refuel and to scheduled maintenance, or avoid deferring maintenance that cannot fit within the shortened down time window? In the present case they seem to even be willing to run at reduced power rather than to promptly address the broken cooling tower. Was the ungreased bearing that caused their SCRAM on a list that just got skipped to get more up time? They give the impression that controlling costs it their primary function.

Nuclear power does have a safety culture, using systems like lessons-learned to attempt to improve safety. But, pushing aging reactors past their design capacity or refueling faster with fewer people seem like lessons learned just waiting to happen. Shoestring methods lack the kind of redundancy that provides for safety margins.
