Objective To prevent damage to the reactor or excessive release of radioactive materials in the event of an experiment failure.
Specification
- a. Experiments containing materials corrosive to reactor components or which contain liquid or gaseous, fissionable materials shall be doubly encapsulated.
- b. Explosive materials shall not be inserted into experimental facilities or the reactor or stored within the confines of the reactor facility.
