Experts from leading scientific institutes of Ukraine - "Kievenergoprojekt" (KIEP), Research Institute of building structures, RI "Stalkonstruktsiya" named after Shymanowsky, NPPs Safety Problems Institute started their work at ChNPP on February 20. Consultations with experts of these institutes are underway since February 15. Today the meeting will hold directly at Chernobyl NPP site. It is expected that on February 23 experts will present their assessment of the collapse reasons and recommendations on corrective and stabilization measures.
Since February 13 two commissions on investigation of partial damage of Turbine Hall constructions are working at Chernobyl NPP. One commission was created by Decree of ChNPP General Director, the second – upon requirement of SNRIU. Representatives from the State Nuclear Safety Inspection at SSE "Chornobyl NPP" site are involved in the second commission. Commission's task is to analyze the situation resulted in damage of building constrictions, to provide proposals for consequences elimination and to develop and agree with SNRIU corrective measures for additional drain water and contaminated dust management, which can be generated within the time necessary to restore a damaged roof and side walls of Unit 4 Turbine Hall.
