Dr L. V. Krishnan's article is quite informative and one is pleased to learn that India's neutronic data about thorium in reactors is now accepted by the international community and IAEA. However work in this area is very slow despite the fact that India is the only country which has sustained interest. The first rods of thorium were inserted in the CIRUS reactor in the year 1960 and even to day we do not know if a thermal reactor can be built utilising thorium even to the extent of 10 to 15% as fuel. The BARC scientists are to be complimented for coming out with the design of AHWR concept and let us all hope early construction and operation of this unit will pave the way for thorium utilisation which we have been talking about since last 45 years.
