Jodhpur: Realising the significance of cooling power sources in nuclear power plants safety based on the historical nuke disasters, an international team led by researchers at the Indian Institute of Technology (IIT) Jodhpur have proposed offshore wind farms as seismically resilient alternate power sources.
By utilising sustainable wind power, the researchers demonstrated the feasibility of strengthening the reliability of cooling power at Madras Atomic Power Station in Chennai. The proposed methodology, published in an article in the journal Nuclear Engineering and Design, involves a series of stages.
It commences with the estimation of coolant power needs in nuclear reactors, followed by the design of an offshore wind turbine and its corresponding infrastructure. Finally, a seismic safety evaluation was conducted on the selected offshore wind turbine site, considering different scenario levels.
The researchers, including from universities of Surrey in UK, Tsinghua, as well as Institute of Engineering Mechanics in China, stated that the proposed 15 MW offshore wind farm with three NREL 5 MW turbines supported by monopile foundations at the Kalpakkam area could potentially act as the additional emergency backup power source for meeting the cooling power requirements of existing nuclear power plants.
The offshore wind turbines monopile foundation was analysed under anticipated dynamic loading conditions considering the soil nonlinearity and seismic liquefaction employing the state-of-the-art numerical models.
The nonlinear integrated seismic analyses conducted on the proposed offshore wind turbines depicted acceptable seismic performance on comparing the monopile mudline displacements and bending moments.
