first_imgAs of 4 pm, today, Vermont Yankee is operating at 94 percent power with a net electrical output of ~589 megawatts. The plant has been operating continuously for 522 days since the last refueling outage back in 2008.  The reduced power output indicates the gradual depletion of the fuel as this operating cycle winds down. The main activity on the plant site is the preparation for the refueling and maintenance outage. Vermont Yankee is bringing in workers from other Entergy plants in the fleet and 800 specialized contractors. Temporary office trailers and cargo containers for such materials as scaffolding are being set up around the site. The construction of the new VELCO switchyard just to the north of the plant site required VY to make some changes to the parking plan for this outage. A temporary parking lot has been set up for more than 700 cars across Route 142 by the town hall in Vernon in the Cersosimo lumber company storage area with service by shuttle buses.     The team conducting the groundwater remediation reports that they have pumped more than 30,000 gallons of groundwater into temporary, on-site storage tanks. Once cleaned, the water is being stored and transferred into the plant for reuse as needed.The groundwater monitoring continues to show a west to east flow and, as expected, the wells generally further east show a gradual rise in tritium as the wells nearest where the leak occurred have greatly reduced concentration. The hydrologists expect all the wells to ultimately be at reduced concentration as the extraction pumping accelerates cleanup.  The remediation of contaminated soil is still in its engineering phase but on schedule for complete removal and shipping to a federally licensed disposal facility.Source: Vermont Yankee. 4.15.2010last_img
