Dufrane was established in 1985 by Ken Dufrane as “Dufrane and Associates”. Teamed with Lou DeRitis, the company grew and was re-branded to Dufrane Nuclear Shielding, Inc. In the mid-2000s, DNSI was purchased by Josh Brooks. Josh worked side-by-side with Lou learning the craft of nuclear shielding, until Lou’s passing in recent years. Josh recognized the need to expand the DNSI offerings to the nuclear industry and began assembling a team of people with very diverse and extensive nuclear careers. In addition to shielding, the DNSI Value Engineering Team is skilled in cask transport, remote waste handling, waste packaging, rigging, large components and D&D. See “Value Engineering Team” on the Services Tab for more information.
DNSI is headquartered in Winsted, CT.
