In 2015 Ramsey commended the Government of South Australia for initiating the Nuclear Fuel Cycle Royal Commission. Commencing in March 2015, the Commission was tasked to investigate the opportunities and risk of further nuclear industrial development for South Australia, which includes mining, processing, power generation and waste management. He said of the decision:
"I congratulate the Premier on this move; we simply cannot make sensible informed decisions about this industry if we don't talk about it."[4]
Ramsey supports the potential storage of low and intermediate level nuclear waste in his electorate of Grey. He intended to nominate his own property as a potential candidate site, but was advised not to by Minister Ian Macfarlane due to a perceived conflict of interest.[5] He told the media:
"I would be more than happy, for instance, to host it on my farm. But I wouldn't nominate my farm without actually speaking to my neighbours and having a community consultation."[6]
Up to four sites within his electorate have been nominated.[5]
Ramsey retained the seat at the 2016 election for Grey with a reduced margin of 1.95% over Broadfoot.[9] He comfortably retained the seat at the 2019 election for Grey with a margin of 13.32% (a two-party preferred swing of 5.57% toward him) over Labor, with Broadfoot finishing fourth.[10]
