Radioactive Isotopes and Nuclear Reactors

1. List 10 contrasting uses for radioactive isotopes. Medical uses:1)Used for manipulation of hematopoietic forms of tumours2)Used for the sterilisation of syringes and other medical equipmentUses in aliment preservation:3)Used to halt the sprouting of root crops after harvest4)Used to tearing death parasites and pests5)Used to control the ripening of fruits and ve puffablesUses in mining and industry:6)Used to read welds and detect leaks7)Used to study the rate of wear and erosion of metals8)Used for analysis of minerals and fuelsEnvironmental uses:9)Used to trace and analyze pollutants10)Used to study the movement of rally urine and to measure precipitation runoffs2. Briefly describe third different nuclear reactor/designs. 1)Light Water Reactor (LWR) ? In this reactor design, illume peeing (ordinary pee) is used to both still the reactor and act as a neutron moderator (a medium which reduces the repair of immobile neutrons). This is the well-nigh widespre ad design in the world, and most nuclear power plants atomic number 18 of this type. The cardinal most common types of LWRs are pressurized water reactors and boiling water reactors. 2) arduous Water Reactor (HWR) ? In this design, lumbering water is used as a moderator and coolant. Heavy water is collected of Hydrogen-2 atoms, or hydrogen isotopes with a agglomerate number of 2. Because heavy water is a much let on moderator that light water, the natural uranium can be used.

The Canadian CANDU reactor is an example. 3)Gas Cooled Reactor (GCR) ? In this design, graphite is used as the moderator and bollix up (u sually carbon dioxide or helium) as the cool! ant. This is a actually out of date design and such reactors are no weeklong constructed. The first gear GCR was the Calder Hall power plant built in Britain in 1955.
