Radioactive Isotopes and Nuclear Reactors

1. List 10 tell apart uses for radioactive isotopes. Medical uses:1)Used for discussion of hematopoietic forms of tumours2)Used for the sterilisation of syringes and otherwise medical equipmentUses in nutriment preservation:3)Used to halt the burgeon forth of root crops after harvest4)Used to crazy death parasites and pests5)Used to control the mature of fruits and ve get alongablesUses in mining and perseverance:6)Used to read welds and detect leaks7)Used to reading the rate of wear and wearing of metals8)Used for analysis of minerals and fuelsEnvironmental uses:9)Used to trace and contemplate pollutants10)Used to study the movement of egress urine and to measure rushing runoffs2. Briefly describe trine different nuclear reactor/designs. 1)Light Water reactor (LWR) ? In this reactor design, trip out piss (ordinary peeing) is used to both collected the reactor and act as a neutron moderator (a medium which reduces the hurrying of immobile neutrons). This is the well-nigh widespread design in the world, and most nuclear power bases nuclear number 18 of this type. The 2 most common types of LWRs argon pressurized water system reactors and boiling water reactors. 2) arduous Water Reactor (HWR) ? In this design, grievous water is used as a moderator and coolant. Heavy water is placid of Hydrogen-2 atoms, or hydrogen isotopes with a agglomerate number of 2. Because heavy water is a oft let on moderator that light water, the natural uranium canister be used.

The Canadian CANDU reactor is an example. 3)Gas Cooled Reactor (GCR) ? In this design, black lead is used as the moderator and muff (usually carbon dioxide or helium) as the coolant. This is a actually quondam(a) design and such reactors are no weeklong constructed. The startle GCR was the Calder Hall power plant built in Britain in 1955.
