Fireproofing inadequate at Japan nuclear reactors: Report
TOKYO (AFP) - Japanese regulators have found inadequate fireproofing at more than one fifth of the nuclear reactors that went offline after the 2011 Fukushima crisis, a major daily said on Tuesday.
The finding could delay their restart by several years in some cases, the Mainichi Shimbun said.
More than 10 of Japan's 50 reactors, excluding those at Fukushima, have flaws in fireproofing, the paper quoted sources at the industry ministry and the Nuclear Regulation Authority (NRA) as saying.
The Mainichi said these include the use of combustible electrical cables and equipment and machines sited too close together, potentially allowing a fire to spread even though the equipment is indispensable for maintaining safety.
