[0076] In an embodiment of the present invention, the accident risk and parameter assessment interface includes: a plurality of auxiliary tool modules; wherein each auxiliary tool module is used to receive a trigger operation of a user and perform corresponding accident risk judgment and parameter estimation according to the trigger operation.

Finally, after completing the sub-item action, the severe accident control decision sheet is generated by writing and approving the execution (writing person: technical team leader, approving person: emergency commander, executor: shift leader) process, and then the system automatically calls the fax server to automatically send the fax to the designated external unit.
