Criticality Safety Analysis of Spent Fuel Storage Pool for NPP Mochovce using MCNP5 Code

نویسندگان

چکیده

The paper presents results of nuclear criticality safety analysis spent fuel storage and handling for the 1st 2nd unit NPP Mochovce. Spent pool (compact reserve grid) T-12 transport cask were modeled using Monte Carlo code MCNP5. Conservative approach was applied calculation max eff k values performed normal various postulated emergency conditions in order to evaluate final maximal values. requirement current regulations ensure 5% subcriticality met except some especially conservative cases.

Thermal assessment of new Ignalina NPP casks for spent nuclear fuel storage at some abnormal conditions

For interim storage of spent nuclear fuel (SNF) at the Ignalina Nuclear Power Plant (INPP), the so-called “dry” storage technology has been chosen. In this case, SNF after a cooling (pre-storage) period in water pools (no less than 5 years) is placed into GNS (Germany) manufactured metal CASTOR ® RBMK-1500 or reinforced concrete CONSTOR ® RBMK-1500 casks and may be stored for at least 50 years ...

Spent Fuel Pool Human Reliability Analysis (HRA), Draft for Comment

One of the key issues that has emerged in performing a probabilistic risk assessment (PRA) for the spent fuel pool during the decommissioning phase of a nuclear power plant's lifecycle is how much credit can be given to the operating staff to respond to an incident that impacts the spent fuel pool that would, if not attended to, lead to a loss of cooling of the spent fuel and eventually to a zi...

Modal Analysis of Spent Fuel Cask for WWER-1000 Reactors

The Spent Fuel Assemblies (SFAs) of WWER-1000 reactors are planned to be transported by special containers which are supposed to be designed in a manner to stand against vibrations and impacts in order to protect the spent fuel from any possible damage. The vibration opposition of these containers shall be far beyond the critical resonance, because the resonances about the natural frequency of ...
