Kosmata helped construct the K Reactor before he lawas assigned to “Reactor Design Analysis,” a team of physicists, mathematicians, and mechanical engineers that were tasked with designing a new, re-circulating reactor. After a year of planning, Kosmata and his team finalized the basis of what would become the “New Production Reactor,” or N Reactor.
