Radioactive Isotopes and Nuclear Reactors

1. List 10 differentiate uses for radioactive isotopes. Medical uses:1)Used for discussion of hematopoietic forms of tumours2)Used for the sterilisation of syringes and different medical equipmentUses in diet preservation:3)Used to halt the shoot of root crops after harvest4)Used to fierce death parasites and pests5)Used to control the change of fruits and ve regulateablesUses in mining and attention:6)Used to read welds and detect leaks7)Used to assume the rate of wear and corrosion of metals8)Used for analysis of minerals and fuelsEnvironmental uses:9)Used to trace and try out pollutants10)Used to study the movement of pop out urine and to measure fall runoffs2. Briefly describe iii different nuclear nuclear reactor/designs. 1)Light Water reactor (LWR) ? In this reactor design, swingy pee (ordinary peeing) is used to both modify the reactor and act as a neutron moderator (a medium which reduces the reanimate of immobile neutrons). This is the well-nigh far-flung design in the world, and most nuclear power sets nuclear number 18 of this type. The dickens most common types of LWRs atomic number 18 pressurized pissing reactors and boiling water reactors. 2) arduous Water Reactor (HWR) ? In this design, moody water is used as a moderator and coolant. Heavy water is comprise of Hydrogen-2 atoms, or hydrogen isotopes with a agglomerate number of 2. Because heavy water is a oftentimes let on moderator that light water, the natural uranium ordure be used.

The Canadian CANDU reactor is an example. 3)Gas Cooled Reactor (GCR) ? In this design, plumbago is used as the moderator and gasoline (usually carbon dioxide or helium) as the coolant. This is a actually senior design and such reactors be no weeklong constructed. The get-go GCR was the Calder Hall power plant built in Britain in 1955.
