Marwah, BARC - Member Secretary The National Symposium on Uranium Technology was held at BARC, Bombay during Dec. 13-15,1989 under the auspices of Engi- neering Science Committee of Board of Research in Nuclear Science, Department, of Atomic. Energy. In the context of expanding nuclear power programme in Indiai the need for production of large quantity of uranium fuel from indigeneous resources hardly needs any elaboration. After three decades of experience in this area, it is thus appropriate to pool together the expertise and experience gained in the country during this period in various aspects of uranium technol- ogy like exploration, mining, ore processing, refining and con- version to oxide and metal. This symposium has provided an opportunity to the uranium technologists to interact and exchange their experience and plan future strategies. Being the first symposium on this toppic the response has been excellent as evidenced by the extensive participation and contribution of papers covering almost all aspects of uranium technology. Altogether 69 papers, including invited lectures have been presented and the proceeding* have been brought out in two volumes. It is our hope that this technical coverage of the pro- ceedings and panel discussion would serve as a valuable reference material for uranium technologists in the coming years; We wish to record our sincere thanks to the members of the organising and various other committees, authors of invited lectures, and contributed papers, and panel members for making it possible to bring out this proceedings. The cooperation extended by Head, Library and Information Division, BARC is gratefuly acknowledged. TECHNICAL COMMITEE CONTENTS INAUGURAL SESSION 1. Introductory Remarks by Al Shrl S.
