The full story of the Chernobyl disaster is yet to be disclosed. The initial cause of the accident was a very unlikely violation of the operating procedure and conditions by the plant personnel which showed the design faults of the reactor and the control and protection system rods. The main or root cause of the accident was the inadequate design of the user-machine interaction. Many people involved with the reliability and safety of Nuclear Power Plants now believe that even if the operators had acted correctly their actions would have resulted in the explosion. The main lesson from the Chernobyl accident is that the Nuclear Age calls for a new culture and and can certainly not tolerate ignorance. Chernobyl is a severe warning of what can happen if people disregard the necessity of including ergonomics in the process of designing and operating complex technical facilities.

The Difference

The dynamical assessment has been performed in the aspect of the nuclear power plants (NPPs) security. The physical protection system (PPS) is constructed by the cyber security evaluation tool (CSET) for the nuclear security assessment. The systems thinking algorithm is used for the quantifications by the Vensim software package. There is a period of 60 years which is the life time of NPPs' operation. The maximum possibility happens as 3.59 in the 30th year. The minimum value is done as 1.26 in the 55th year. The difference is about 2.85 times. The results of the case with time delay have shown that the maximum possibility of terror or sabotage incident happens as 447.42 in the 58th year and the minimum value happens as 89.77 in the 51st year. The difference is about 4.98 times. Hence, if the sabotage happens, the worst case is that the intruder can attack the target of the nuclear material in about one and a half hours. The general NPPs are modeled in the study and controlled by the systematic procedures.
