“…First, the guide tube had to be cut into two parts using a "specially designed remote cutting machine" while ensuring that none of the chips produced during the cutting process fell into the core. 8 Then the damaged reflector subassemblies had to be identified using a periscope. Finally part of the sodium had to be drained out and the damaged subassemblies removed using specially designed grippers.…”

India has long pursued a fast breeder program, motivated in part by the availability of only poor quality uranium resources within the country. But progress so far has been disappointing, with only one test reactor having been constructed and having a chequered operating history. The larger Prototype Fast Breeder Reactor that is being constructed has a design that compromises safety and will produce expensive electricity, but could be used as a way to convert reactor-grade plutonium to weapon-grade plutonium. Projections offered by the nuclear establishment of fast growth of breeder reactors are methodologically flawed and based on very optimistic assumptions.

“…The requirements of ISI of various components of PFBR have been considered at the design stage itself and it is ensured that these requirements are met participating to ensure safe and reliable operation of the reactor systems. The components which cannot be inspected during the service life of the reactor have been identified and special care in design has been taken and stringent fabrication quality has been imposed (Srinivasan et al, 2006;Velusamy et al, 2010). One of the important components of the PFBR that required special attention and extensive developmental efforts toward ISI is the inspection of main vessel and safety vessel.…”

Abstract. Knowledge of temperature fluctuations in fast reactor subassembly is very important from a safety point of view. The time constant of thermocouples which are used for measuring coolant temperature in a fast reactor varies owing to various factors. Hence, it becomes necessary to investigate the effect of change in the time constant on sensed fluctuations. This paper investigates the dependence of temperature fluctuations on thermocouple time constants. A Scilab model consisting of source temperature profile, second-order thermocouple and histogram calculation is designed. Simulation is performed for various levels of fluctuations, fixed and variable thermocouple time constants. Kurtosis for each condition is calculated with the help of a histogram. It is found that the effect of true source fluctuations on sensor output is very large compared to that of a similar percentage of time-constant variations. Hence in systems like fast reactors, where the degree of source fluctuations (fluid enthalpy) is large in comparison to that of time-constant variations, the overall effect can be considered with great confidence to be the outcome of coolant temperature rather than thermocouple time-constant variations.
