Japan’s NRA may change nuclear waste burial rules, increase depth

flag-japanNRA panel wants deeper disposal for nuclear waste http://www3.nhk.or.jp/nhkworld/english/news/20151211_01.html  A team of experts at Japan’s nuclear regulator has proposed that nuclear waste with relatively high levels of radiation be buried deeper underground than current law requires.

The team at the Nuclear Regulation Authority, or NRA, presented a draft of regulations for such waste on Thursday. The waste comes from the decommissioning of reactors. The draft calls for such waste to be buried at least 70 meters underground. This is to prevent people from approaching the waste.

Current law requires that waste with low or relatively high levels of radiation be buried at least 50 meters underground. The draft requires utilities to maintain buried waste for 300 to 400 years.

The draft also would have the central government prepare a system to prevent the buried waste from being dug up after the maintenance period ends. The NRA team plans to gather opinions from the Federation of Electric Power Companies of Japan and compile basic ideas by the end of next March.
