In an apparent bid to win support for the restart of nuclear power plants, the state has quietly expanded the scope of subsidies for host cities to include local governments within 30 kilometers of the facilities, a charge the government denied Friday.

The change came into force in April with no announcement to the media from the industry ministry, fueling speculation that it was meant to assuage the concerns of municipalities surrounding host cities about plants taken offline in the wake of the 2011 Fukushima nuclear crisis.

A government official, however, denied this speculation.
