VY may extract tainted water from under plant

Engineers are working on a plan to extract up to 300,000 gallons of
tritium contaminated groundwater from under the site of Vermont Yankee
nuclear power plant in Vernon.
Once extracted, the water would be filtered and re-used in the power
plant, according to the Vermont Department of Public Health in its daily
update posted on its Web site.
The filtering process does not remove tritium from the water, said Ray
Shadis, technical director of the New England Coalition on Nuclear
Pollution, which opposes the relicensing of the plant.
It only removes organic particles from the ground sucked up with the
contaminated water, he said.
An option to filtering the water for re-use, said Shadis, is
for Yankee to get permission to extract it, mix it with water from the
Connecticut River and dump it back into the waterway.
Shadis called it the "solution to pollution is dilution" remedy.
If the tritiated water is filtered for re-use in the plant, said Arnie
Gundersen, a critic of Entergy's operation of the plant and a member of
the Public Oversight Panel tasked with reviewing a reliability
assessment of the plant, the tritium would eventually be released out of
the plant's stack as part of Yankee's regulated gaseous emissions.
Gundersen also said the amount needing extraction could be more in the
range of 1 million gallons, not just 300,000 gallons.
He questioned where the contaminated water would
be stored between extraction and filtering.
Some of it could be stored in the plant's 500,000-gallon condensate
storage tank, but those tanks normally contain 300,000 to 400,000
gallons, he said.
A condensate storage tank is used to store excess condensate and water
as an emergency water source in case of a loss-of-coolant accident in a
boiling water reactor. The tank is considered to be a safety-related
component.
Because the tank is kept close to its capacity, most of the extracted
water would need to be stored in large above-ground bladders or tanker
trucks, he said.
Entergy, which owns and operates Yankee, has applied to the Nuclear
Regulatory Commission to extend the operating license of the power plant
for another 20 years, from 2012 to 2032.
Recently, the Vermont Senate voted 26 to 4 in opposition to its
continued operation.
Hearings being held by the Vermont Public Service Board to determine if
the plant should receive a certificate of public good for continued
operation are currently on hold pending an investigation into inaccurate
statements made by Yankee representatives about the nature of
underground piping at the plant.
