Atlas Copco HB 7000 breaker turns a nuclear facility into a valuable property


Indiana’s only nuclear facility “Marble Hill” hasn’t been notable for anything other than being an eyesore and a 30-year-old unfinished project. Now MCM Management Corp. is reclaiming the property with the help of Atlas Copco HB 7000 breakers and is turning it into a valuable piece of riverside land. MCM is clearing administrative buildings, outbuildings and thick concrete and rebar-covered silo and containment structures built literally nuclear blast proof. 

Even though the nuclear facility wasn’t ever operational, the construction was designed to contain a tremendous amount of pressure. Mark Ramun, vice president of MCM Management, said, “Nobody ever considered how it would be to take apart. Conventional tools don’t exist to handle it.”
Denise Brown, MCM site manager, adds, “We worked three days on one section with a competitive breaker and when we put on the Atlas Copco HB 7000 the same amount of work was completed in three hours – these hammers are pretty amazing really.”
The hydraulic breaker’s job is to expose the rebar so the silos can be imploded and laid over on their sides and to remove the concrete structure separating the two silos. The silos would not tip if the structure behind is intact. The breakers have to remove the building to allow for that break point.
Ramun said, “This is our first experience with an Atlas Copco breaker. If these hammers continue to perform like they have, I think it’s safe to say that we’ll be sticking with Atlas Copco in the future.”
