Abstract: A Control Neutron Absorber (CNA) assembly for a microreactor that produces nuclear energy is disclosed. The CNA assembly includes a housing, a CNA rod, and a burnable absorber. The housing includes an inner housing and an outer housing. The inner housing is configured to receive a CNA rod. The outer housing extends coaxially with the inner housing and is positioned radially outward and offset from the inner housing defining a cavity therebetween. The CNA rod includes a neutron absorbing rod including a first neutron absorbing material. The neutron absorbing rod is positioned within the inner housing and is configured to move axially relative to the inner housing. The burnable absorber includes a second neutron absorbing material, exhibits a neutron absorbing strength that is less than that of the neutron absorbing rod, is positioned within the inner housing, and is configured to receive the neutron absorbing rod therein.

Abstract: The present invention relates to an improvement in the process of and a device for shredding scrap automobiles, trucks, appliances, white goods and the like, which improvement substantially reduces and in most cases eliminates the damage from explosions during the process of and within the equipment for shredding scrap automobiles, trucks, white goods and the like by adequately venting the equipment during the process so as to prevent pressure build-up within the system after initiation of an explosion.
