MCNP Case Study – Dry Cask Shielding

Tuesday, March 28th, 2017

We were contracted to build a complete Dry Cask shielding package for a BWR plant that had never done a Dry Cask campaign before and who was using a storage system that had never been used at a BWR before. The design challenge was to work within a given weight limit and provide the maximum dose reduction possible without adding any weight to the work platform.

Neutron Radiation: The Concern, Reason, and Solution

Thursday, December 1st, 2016

Nuclear Power Outfitters (NPO) offers a wide range of materials that can be used to attenuate neutron radiation. In contrast to the high density/high atomic weight element materials used for gamma attenuation (lead, bismuth, tungsten), neutron radiation is most effectively shielded using relatively low density materials with high hydrogen content, such as water or high density polyethylene.
