Japanâs new nuclear watchdog agency, the Nuclear Regulation Authority, issued its first set of proposed changes to nuclear plant safety guidelines Jan. 31, The Wall Street Journal reports.
The new rules, implemented in response to the Fukushima meltdown, will require plants to have multiple access points to the external power grid as well as enhanced filtration systems to prevent contamination outside of the plant in the event that reactors need to be vented. The newly proposed rules are now open to public comment.
The changes bring Japanese nuclear regulations up to the level of U.S. regulations in some instances â U.S. nuclear plants are already required to have a minimum of two connections to the external power grid, for example, and many venting valves are already mandated to have filtration systems installed.
