Hydrogen Explosion Risk in Nuclear Power Plants - Hydrogen Re-combiners to the Rescue
The accumulation of hydrogen gas in large volumes takes place during core meltdown accidents inside the containment of light and heavy water nuclear power reactors. The hydrogen gas combines with air and water vapor; and when this mixture of gases exceeds the flammability threshold, there is a high risk of explosion, resulting in a radiation leak from the containment building into the atmosphere. If the radiation escapes into the atmosphere, this is classed as an environmental disaster, and puts the public in the vicinity of the power plant at significant risk. Power plants formulate a range of strategies and ensure that power plants are properly equipped in order to mitigate the risk of a hydrogen explosion. One of the main strategies believed by nuclear experts to mitigate the risk of a hydrogen explosion is the installation of Passive Auto-catalytic Hydrogen Re-combiners/ Passive Auto-catalytic Re-combiners (PAHRs or PARs) in nuclear power plants. The role of hydrogen re-combiners during nuclear accidents is crucial, and the equipment has already been installed in nuclear power reactors in the US, Germany and France. India intends to install hydrogen re-combiners in all of its 20 nuclear power plants. Following Japan’s nuclear crisis, the likelihood of this equipment being installed in nuclear facilities is expected to increase throughout the forecast period 2011-2020. Equipping facilities with passive hydrogen re-combiners and increasing safety measures in nuclear facilities will become a priority for the nuclear power industry in terms of ensuring nuclear safety.
