Development of Hull Compaction System for Nuclear Recycle Facility

Abstract: India has adopted closed fuel cycle strategy for efficient management of available resources to meet long term energy requirements. Nuclear Recycle Facility (NRF) provides a vital link in three-stage Indian nuclear power programme. In a NRF for PHWR fuel cycle, reprocessing of spent fuel bundles from PHWRs is carried out using a chop-leach process where the spent fuel bundles are chopped into small pieces using a spent fuel chopper and the contents inside the zircaloy clad are dissolved using concentric nitric acid. This process generates empty zircaloy shells called ‘hulls’. The present practice followed for management of hulls is to transfer them into SS drums and store these drums in underground RCC tile holes at a Waste Management Facility (WMF). This waste needs to be stored in an engineered WMF for at least 30-60 years before transferred to a final repository. The storage volumes required for this hull waste will keep increasing as the reprocessing capacity is being enhanced multi-folds. Compaction of hull waste has been employed internationally to reduce the volume required for storage. Hence indigenous development of hull compaction system was initiated by NRB to meet the future requirements. This is being achieved through a set of experiments and analysis with the available resources within the country. This paper describes the process of compaction, conceptualization of the system and benefits accrued from it.

Feasibility of In-Situ Process Monitoring of Glass Melt in Industrial Furnace using Microwaves

Abstract: Non-contact measurement of the level of molten glass is demonstrated in an engineering scale induction-heated glass melter using microwaves. The microwave sensor is a corrugated horn used in mono static RADAR (RAdio Detection and Ranging) mode operating over 20 to 24 GHz with 20 dB gain. The ability to measure the level of the glass melt is demonstrated using an off-centered port in an induction glass melting furnace.

Site-Specific Factors to Derive Maximum 1-hourly to 6-hourly Continuous Rainfall from Daily Extreme Rainfall on West Coast of India

Abstract: Continuous daily rainfall records are generally available for most locations in India. In the absence of generic temporal distribution of rainfall for any site, hydraulic designers resort to factors obtained from temporal distribution curves in the literature to arrive at design n-hour rainfall value (n < 24) from the design daily extreme rainfall. In literature, adoption of temporal distribution from site data has been advocated for important structures. In this article, rainfall records from a western coastal site in India are first used to establish that the 1-h factors would be comparable when obtained from 53-year (1961–2013) annual extreme rainfall data and 17-year (1997–2013) monthly monsoon extreme rainfall data. It was shown that the 1-h factor estimated from short period monthly records could yield better estimates when applied on longer period annual maxima to derive 1-h maximum rainfall, when compared to the factors from generic temporal distribution curves in literature. Using this philosophy, the n-hour factors up to 6-h maximum continuous rainfall are estimated from the continuous hourly rainfall records available for the site (1997–2013). The n-hour factor was higher for lower daily rainfall value, up to 6 h. Temporal distribution factors for n-hour (n ≤ 6) continuous rainfall have been recommended for various maximum daily rainfall ranges, which, when compared to those from literature, would be better suited for this site, and possibly for the surrounding region as well.
