(I)

it is highly unlikely that an accident like what took place at the Chernobyl RBMK nuclear power plant would happen to a PWR; (Ref :

a PWR; (Ref: 2.1.15; 3.1.2; 4.6.4)

(4) an

and

additional safety feature has been developed adopted by France and other countries for

modification of existing plants to reduce the build-up of pressure to a safe level, where necessary, inside the containment building in case of a severe accident. This is done by means of a controlled sand filter system, the usefulness of which is recognized by IAEA; (Ref : 2.1.16; 3.1.15)

all improvements developed for control room design as a result of the Three Mile Island accident have been incorporated in the design for the Daya Bay Plant; (Ref: 2.1.18)

(6) the question of metal fatigue affecting the material used for the reactor pressure vessel has been resolved; (Ref: 2.1.10)

(7) the cost of nuclear power varies from country to country, and while in other countries the average. cost of nuclear generated power is cheaper than coal-fired generated power,

in USA nuclear- generated power is more expensive than coal-fired generated power; (Ref: 3.8.11; 4.1.3)

(8) the safety of a nuclear power plant depends to a

great extent on safe operation by a well trained

operation crew.

In France, USA and Japan
