The state Public Service Board won’t reconsider its approval of storage capacity for radioactive waste at Vermont Yankee.
The board rejected the request from the New England Coalition, an anti-nuclear group, to reconsider the approval.
The Coalition wanted an earthen berm to be built on the two most exposed sides of the planned waste storage site.
The coalition had argued in board hearings that the berm or a similar structure would protect the site from terrorist attacks.
The board said even if it adopted the coalition’s proposal, other parts of the nuclear plant would remain exposed, so little would be gained.
