EnergySolutions Inc., the owner of the largest private U.S. disposal site for low-level radioactive waste, said ENV Holdings LLC will sell 35 million shares in the company.

ENV will cut its stake in the Salt Lake City-based nuclear-services company to 22.7 percent from 62.3 percent, EnergySolutions said Monday in a U.S. Securities and Exchange Commission filing.

EnergySolutions will not receive any proceeds from the proposed offering, the company said in a news release. ENV Holdings is controlled by affiliates of Lindsay Goldberg, Peterson Partners LP and certain members of the management of EnergySolutions.
