Role of technical specifications in the safety of heavy water plants (Paper No. 4.2)

During the operation of any plant, certain situations may arise due to various reasons which may result in a deviation from the normal operating conditions. It is necessary to ensure that such a deviation would not result in a condition which would have serious safety implications. Therefore it is essential to identify parameters and set limits to ensure safety. These limits are brought out in the technical specifications. Technical specifications define the limiting conditions of operation so as to ensure the safety and health of the plant, personnel working in the plant and the general public. This applies to the various areas of the plant operation such as monitoring systems, fire protection systems, effluent systems, electrical systems, instrument air systems, personnel protective systems, man power requirements etc. These aspects are discussed.
