Glucinium, later named beryllium, was discovered in the late 18th century. Its first use by Chadwick in the 1930s and beryllium moderating properties in the 1940s opened the door for beryllium nuclear applications.

Safety classification in the design of a nuclear reactor is used to create the appropriate technical requirements for its systems, structures and components (SSC). Based on the assigned safety class, in order to reach the expected level of safety performance, items important to safety have more strict requirements for their technical characteristics, design, testing and manufacturing process and maintenance procedures.
