Advanced Membrane Degassing Technology For Radiation Source Term Reduction And Corrosion Control In Nuclear Power Plants
By 3M Separation and Purification Sciences Division

Dissolved gas control in a nuclear power plant’s water system, including the primary make-up water storage tank and refueling water storage tank, can be essential to reduce radiation source term (defined as a release of radioactive material). In particular, controlling dissolved gases can also help reduce the formation of unwanted radionuclides, such as 14C and oxides of 60Co, and alleviate primary water stress corrosion cracking (PWSCC).

Quick Facts: SO3 Control – Not Just To Cure The Blues!

SO3, or the Blue Plume, is not as notorious as SO2, Hg, or HCl – but nonetheless is an air pollutant to be reckoned with. “Quick Facts: SO3 Control – Not Just to Cure the Blues!” offers brief questions and answers about what it is, and how and why it should be treated – most notably its impact on mercury capture.

Ion Exchange Treatment Of Regulated Metals In Coal Ash Found To Be Efficient In Power Industry

Coal ash is a waste product of coal combustion used for electrical power generation. Fly ash (from smoke stacks) and bottom ash (from boilers and combustion chambers) may contain trace metals including aluminum, arsenic, cadmium, chrome, copper, mercury, nickel, lead, selenium, vanadium, and zinc. This ash is removed from the boiler using a water slurry and stored in holding basins or ash piles within the power generation facility.
