A TEPCO investigation into a slow leak affecting the Fukushima Daiichi unit 4 spent fuel pool alternative cooling system has found a likely cause. Corrosion was found on a weld between a flexible and fixed hose connection. TEPCO's preliminary analysis concludes that the corrosion was most likely caused by the high temperature of the water at the start (80°C) and high chloride (salt) content of the water (2000 ppm). A destructive test using penetrant testing and electromicrosopy revealed the hole.
