ALARA IMPLEMENTATION AND KNOWLEDGE MANAGEMENT IN NUCLEAR POWER PLANTS

Radiation protection procedures are being followed in operating power plants aiming at reduction of exposure to ionising radiation to the occupational workers and keeping the radiation levels “As Low As Reasonably Achievable (ALARA)”. The protection against radioactivity is being envisaged in an operating plant depending upon activities that include selection of the material used for the reactor components, decontamination of contaminated equipment, maintenance or replacement of contaminated component, radioactive waste transport etc., During maintenance of reactor or other radioactive components the chances of spread of contamination is high and therefore extensive exposure control measures have to be implemented. Contamination is the presence of radioactive material where its existence is undesired.
