Core Barrel Shielding

April 11, 2017

In 2013 NPO designed and built a custom Core Barrel Shield for Palisades Nuclear Plant in Covert, MI. The shielding was implemented in Palisades’ 23rd refueling outage and was a great success. The story of the project’s success spread in May 2015 when the Palisades plant was recognized during the Nuclear Energy Institute’s best industry practice […]

Steam Dryer Flood Up Water Shielding

July 28, 2016

Tungsten T-Flex® was selected as the best material to shield divers during a Steam Dryer repair. Approval for use in flood up water required chemical testing for leachables and heavy metals. The end result was an 8 ft x 5 ft (2.44 m x 1.52 m) shield wall constructed by attaching T-Flex panels to a […]

Lower Dry Cask Barrel Shield

March 9, 2016

Some NPP’s process Dry Casks in a such a way that the entire cask produces a general area dose concern. To reduce these dose rates NPO developed a shield package that sits on the floor and shields the cask to a height of 9 feet (2.74 m). NPO is currently under contract to provide shield […]

NPO uses MCNP to simulate Dry Cask

March 9, 2016

Dry Cask processing operations present a number of complex radiological challenges. The presence of both neutron and gamma radiation coupled with the varying amounts of shielding already provided by the cask and canister make it difficult to know where to put shielding and what type shielding to use. Additionally, shielding limitations often exist in the […]
