Australia will soon sell uranium to Ukraine for power generation.
Foreign Minister Julie Bishop will arrive in the United States on Wednesday for a global nuclear security summit and will also attend a dinner meeting at the White House hosted by President Barack Obama.
She will have talks with British, Dutch and Singaporean leaders and foreign minister counterparts.
At the summit, leaders will discuss ongoing international co-operation on nuclear security and the threat of terrorists acquiring nuclear material or sabotaging nuclear facilities.
Ms Bishop will also sign an agreement with Ukrainian President Petro Poroshenko to supply uranium for power.
Australia already supplies uranium to Canada, China, France, India, Japan, South Korea, Russia, the UK and the US.
The Minerals Council of Australia hailed the new uranium export market.
Australia holds almost a third of the world's uranium resources but supplies only around 10 per cent of global production.
In 2014-15 Australia exported more than 5500 tonnes or uranium generating more than half a billion dollars in export income.
"Access to growing Ukrainian uranium demand creates opportunities for more tonnes, more exports, and more jobs in mine construction and operations," council spokesman Daniel Zavattiero said.
