Simulation of the Lower Head Boiling Water Reactor Vessel in a Severe Accident

open access: yesScience and Technology of Nuclear Installations, 2012
The objective of this paper is the simulation and analysis of the BoilingWater Reactor (BWR) lower head during a severe accident. The COUPLE computer code was used in this work to model the heatup of the reactor core material that slumps in the lower ...

Weibull stress analysis for the corner crack in reactor pressure vessel nozzle

open access: yesAdvances in Mechanical Engineering, 2019
The nozzle region of a reactor pressure vessel experiences higher and more complex stresses than the remaining part of the reactor pressure vessel. If a corner crack is postulated in the nozzle region, it is necessary to consider the potential strong ...

Estimation of the error of functionals calculation results of the neutron flux onto the WWER 1000 reactor pressure vessel [PDF]

open access: yesЯдерна фізика та енергетика, 2012
It is shown that systematic calculation errors of functionals of the neutron flux onto WWER 1000 reactor pressure vessel are pseudorandom. The error of the neutron flux functionals is estimated on the basis of this fact and the data obtained with the ...

Development of ex-vessel corium coolability analysis program(COCCA) with simplified models validated against FARO experiments

open access: yesNuclear Engineering and Technology
Molten corium may be discharged into the reactor cavity if the Reactor Pressure Vessel (RPV) fails during a severe accident. The cooling and stabilization of the discharged molten corium in the reactor cavity are crucial for preventing further accident ...
