“…Literature also reports the use of commercial soft tools for simulation of thermal dispersion in lakes, rivers and coastal environments [14][15][16][17][18][19][20][21][22][23][24][25][26]. Abbaspour et al [14], Lowe et al [15], Liu et al [16] and Ahmed et al [17] used MIKE software in order to estimate thermal dispersion in coastal and confined water bodies.…”

“…Some authors have accounted for the wind speed over the water body for accurate thermal analysis. Sasmal et al [26] used three-dimensional (3D) Princeton Ocean Model (POM) with a constant momentum flux of reversing wind speeds of 2 and 10 m/s. A wider spread of the plume was demonstrated in their work for low wind speeds.…”

Thermal dispersion of heated effluent in a lake near nuclear power plant is analysed. Lake Bathymetry is established by data collection at a pre-planned matrix of sample points in the lake. Threedimensional geometric model of the lake is developed based on the geometric data collected, using a high accuracy GPS and a dead weight based depth meter at respective sample points of the lake matrix. A turbine type digital flow meter is used to measure the velocities at the intake and blow down points of the lake. Numerical analysis of flow and thermal dispersion is carried out using PLIC-VOF two-phase model with the two-equation k-epsilon model for turbulence closure. Numerical results for varying flow and blow down temperature conditions and wind speed are studied. It is observed that the thermal gradients are steeper in the curved area near the blowdown point. Small increase in main inlet (inlet II) velocity suppresses the dispersion of high-temperature contours significantly. Thermal discharge and dispersed temperature is monitored using temperature sensor mounted floating buoy at various locations in the lake. It is established that the thermal dispersion is influenced by wind velocity and the presence of water hyacinth in the lake.

In the PTTM subroutines incorporated into the Princeton Ocean Model, we use the outfall location as the starting point and incorporate the actual meteorological forcing to follow the trajectory of particles.…”

The present paper is a report of strategic schemes to improve the disaster management advisories for nuclear power plants in India. The response to natural disasters and man-made accidents are treated separately and we provide a methodology for implementing them. Since natural disturbances are fairly predictable a few days in advance, a proper real-time simulation of the atmospheric and oceanic dispersion of the effluents with a good scheme to disseminate the information to general public (through NKN networks) will help in reducing the inconvenience to the people. Seasonal and monsoonal variations in currents, waves and winds will determine where and how far the effluents travel. On the other-hand, man-made errors and accidents being quite unpredictable, a better action plan can be drawn up using a vulnerability ma. We propose that, the vulnerability analysis should be done with the aid of Particle Trajectory Tracking Models (PTTM).
