NPCIL has that the commissioning of KKNPP would now happen only in June, after another set of checks are carried out. The company said the physical progress of the plant was 99.6% complete.
This week a group of 60 leading scientists wrote a letter to the PM, and chief ministers of Tamil Nadu and Kerala asking for more stringent safety checks of the KKNPP. They have sought “renewed study” of safety issues by an independent panel of experts. The scientists — most of them serving in state-run institutions — have expressed doubts, “particularly with reference to possible sub-standard components” used in the plant.
These are not scientists advocating against nuclear energy, but concerned about safety issues. “These safety concerns are compounded by the fact that Russian authorities arrested Sergei Shutov, procurement director of Zio-Podolsk, on corruption charges for having sourced cheaper sub-standard steel for manufacturing components that were used in Russian nuclear installations in Bulgaria, Iran, China and India,” they wrote in the letter, The arrest of Shutov, they cited, led to several complaints of sub-standard components and follow-up investigations in both Bulgaria and China.
While the AERB gave an in-principle clearance for fuel loading of the plant in April, hopes that it would be commissioned by May were dashed after faulty valves made news. In an effort to quell the protests and spiralling negative perception about the power plant, the government has been on an information overdrive to educate and be transparent. This week, minister of state V Narayanasamy said, “All nuclear power projects undergo an elaborate in-depth safety review during the consenting stages, like siting, construction, commissioning, etc. After satisfactory review during project stage, AERB issues operating licence to an NPP for a period of up to five years.”
Last week, responding to a question in Parliament, government assured that components supplied to KKNPP are “tested in an integrated manner during commissioning to verify their performance in accordance to design performance criteria. Any shortfall noticed in performance is addressed/corrected as a part of the commissioning programme”
