Description
Once the spent fuel is removed from the reactor the fission process has stopped, but the spent fuel assemblies still generate significant amounts of radiation and heat and hence must be shipped in containers or casks that shield and contain the radioactivity and dissipate the heat. We have the capability and tie up's with technology partners to cater to such critical requirements.

Description
Volume reduction of radioactive waste is one of the key issues and economic factors for repositories. Super-Compactors are used for reducing the volume of activated and contaminated waste such as core fittings, structural elements of fuel rods, and also low to mid-level radioactive waste.
Super compactors
Description
Cementation, through the use of specially formulated grouts provides a means to immobilise radioactive material that is in various forms of sludges and precipitates/gels (flocks) or activated materials, as well as fragmented solids. In general the solid wastes are placed into containers and the grout is then added into the container and allowed to set.
Cementation technologies
Description
Near Surface Disposal facilitiy is a purpose built and engineered underground cement mound near to the surface for disposal of lightly radioactive material. The walls of such facilities are made of thick specially engineered concrete mixtures to avoid any radiatoin seepage to the surroundings.

Description
Neutron flux monitoring is a very important task when it comes to the operation of a nucelar plant. These are devices that can accurately monitor the nuclear reactor's power and its doubling time. The system consists of neutron flux detectors placed at the vicinity of the reactor and the system can be programmed to regularly monitor th flux and trigger alarms or emergencey shutdowns when the flux is too high or there are any rapid changes.
