- 10 mR/hr Alarm at or below level set to meet requirements of 10 CFR 20 Unit A is the original AGN console Unit B is the ISU all solid state electronic control console Either Unit A or Unit B will be in service any time the reactor is operating 3.3 Limitations on Experiments Applicability This specification applies to experiments installed in the reactor and its experimental facilities.
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.
