Shifting site of proposed NPP
This is in reference to the article, “16 more barrages and Rooppur” by A. B.M. Nurul Islam published in your esteemed daily on 7-11-2014. Even the present lowest flow through the Ganges i.e. 3,100 cusec as reported is not at all sufficient for 2000 MW Nuclear Power Plant. Actual design will determine the exact volume of cooling water requirement. From the rule of thumb, it will be around 8,000 cusec. Hence, the only answer appears to be a cooling tower. This water will, of course, be circulated. Once charged, the cooling tower would need make-up water to replace the amount lost due to evaporation, drift, leaks etc. Depending on the design and weather conditions, the make-up may be 2 to 3 percent.
Given the requirement of cooling water and the transportation of heavy equipment for the NPP to the site, the site may be reconsidered and may be chosen at some sea shore of Bangladesh. Abundant sea water for cooling and the advantage of heavy equipment transportation and ease of handling may be considered.
