MarShield was approached by Lawrence Livermore Laboratory to design and manufacture a custom cabinet so they could store their sources underneath. The cabinet also required a L-block shield and cave on top so they could prepare their unit doses of high-energy sources. The entire cabinet and L-block shield and cave on top have to be completely covered to avoid lead exposure. The client also required the entire cabinet to be rated for seismic activity.

The Lawrence Livermore Laboratory is a federally funded research and development center founded by the University of California in 1952. For the last 60 years, the laboratory has applied science and technology to make the world a safer place. Livermore’s defining responsibility is ensuring the safety, security, and reliability of the nation’s nuclear deterrent. Its science and engineering have been applied to achieve breakthroughs for counterterrorism and non-proliferation, defense and intelligence, energy, and environmental security.

The team at MarShield decided to construct the cabinet using 304 Grade Stainless Steel with a high polished surface to meet the requirements for cleaning and sanitization clean room qualifications. The cabinet will be delivered to the client fully assembled and ready to go other than the glass that needs to be put into place (this is done to ensure proper shipping and handling of the glass).

The design phase was initiated with a plan to have the cave and L-block permanently attached to the cabinet so it could be rated for seismic activity. At this point, anchors were also added to the cabinet so it could be securely bolted to the ground.
