A designed method of removal for insoluble corrosion products would be filters.
Stellite contains a high percentage of cobalt which is highly radioactive via neutron bombardment.
fission products are the most abundant source of radiation during power operation.
Kr-85, Sr-90, and Xe-133 are fissions products. (A > 60)
Fe-59, Mn-59, Mn-54, Cr-51, and Co-58 are activated corrosion products in light water reactors. (A<60)
A leak or venting of primary coolant, a steam leak in a BWR, or breaching a contaminated system are all examples of potential sources of radioactive airborne contamination.
Alpha Gamma interactions are not a source of
fission products in plant systems. The degasifier is a method of removal for noble gasses from the reactor coolant system.
Noble gasses may be removed from reactor coolant through the degasification process, or through degasifier.
A 2000 MW thermal PWR might be expected to produce 640 MW of electrical power. (2000 x .32 = 640)
Release of noble gases in light water power reactors is limited through the decay lines or tanks.
Three sources of reactor coolant radioactivity would be fuel cladding impurities, system corrosion, and impurity introduction.
Activation products are a source of radioactive contamination.
fission products area major factor in power plant radiation source production.
Uranium fuel cladding is more likely source of
fission products in reactor coolant systems than alpha and gamma interaction, plutonium-239 in a fuel rod/pin, or tritium in a high neutron flux environment.
Particulates may be removed from reactor coolant through filtration and ion-exchange in the purification system.
Letdown filters is how you remove corrosion products from reactor coolant system.
The four emergency classifications of an accident at a nuclear power plant are as follows, in descending order: General Emergency, Site Area Emergency, Alert, Unusual Event.
Evaporators are a design method for removal of corrosion products from the reactor coolant system.
When compared to opening a waste gas tank with a negative pressure purge on the tank, cleanup of radioactive sludge oil spill with an absorbent, and pumping a containment sump, removal of HEPA filters from a ventilation unit has the greatest potential for creating an airborne activity area.
