"Would Wagga be ideal [for a nuclear plant]? I don't know the answer to that. It would depend on the infrastructure we have." he said.

"I am so confident in the safety and ability of modern, small modular reactors, I would be prepared to put one in my backyard.

"I would have no qualms with having me and my family live next to one."

Mr Fang made the comments in explaining his support for the NSW National Party backing One Nation's legislation to allow new nuclear power and uranium mining for the first time in more than 30 years.

The upper house MP was also part of the Standing Committee on State Development that urged the NSW government to lift restrictions on the nuclear industry.

"Nuclear technology has improved and there are further promising innovations such as Small Modular Reactors being developed", the report stated.

Mr Fang said these reactors would be different to the designs of power plants that have seen nuclear accidents.

"The vast majority of people, when they think of nuclear power, they go to Chernobyl, they go to Fukushima, they go to Three Mile Island," he said.

"That is comparing 1970s technology with the very cutting edge of what is possible now with nuclear power.

"It's like comparing an old carburetor V8 to a modern four-cylinder engine."

Mr Fang said uranium mining would create jobs in the state's far west and nuclear power would provide cheaper and more reliable electricity while reducing carbon emissions.

Wagga Climate Action Now president Patricia Murray said she doubted Mr Fang would go through with his pledge to accept a nuclear neighbour.

"He says that flippantly now, but if that time came I doubt that. When the reality comes around, it's not a very good option." she said.

"With wind and solar now, why go down a track that has all these dangerous consequences.

"There are delays of something like 20 years to get one of these plants up and running and they need a lot of water for temperature control."

Retired Wagga teacher Bert Adams said the NSW Nationals' support for nuclear power would help bring down prices and replace coal but said federal laws would get in the way.

"It would help the whole nation if we switched to nuclear power. It would be something they could bring in when they close down coal power," he said.

"There are moves to build smaller nuclear reactors that don't use as much water and could be built more quickly."
