Progress report on nuclear data activities in India for the period from January 1986 to June 1987

The present progress report on Nuclear Data Activities in India is the fifth in the current new series of progress reports, the first of which was brought out in the year 1981. This report covers the period from January 1986 to June 1987. It contains information about measurements, evaluations, complilations and processing of nuclear data and other related works being carried out mainly at Bhabha Atomic Research Centre, Bombay and Indira Gandhi Centre for Atomic Research, Kalpakkam, the two nuclear and reactor research Centres in this country. It may be worth mentioning here that an IAEA interregional training course on 'Processing of Nuclear Data for Use in Reactor Applications' was held at Bhabha Atomic Research Centre, Bombay during 31 March - 25 April 1986. This course was designed to provide participants with a working knowledge of the methods currently used to process nuclear data for use in reactor applications. It comprised of lectures as well as computer exercises. The scope of the course included an introduction to currently available nuclear data libraries and their applications in specific reactor applications, processing of resonance parameters, Doppler broadening, the multigroup method and self-shielding. It also included the lectures on the accuracy of the results obtained and on the sensitivity analysis, which can be used to determine the sensitivity of the integral reactor parameters to nuclear data uncertainties.
