CENTRAL Australian traditional owners are part of a Territory delegation making a last-ditch effort to stop the nuclear waste facility in Canberra today.

The Commonwealth Radioactive Waste Management Bill will be tabled in the Senate today.

Eight traditional owners from Harts Range and Mt Everard -- two of the sites nominated for the facility -- are in Canberra with Deputy Chief Minister Syd Stirling, MacDonnell MLA Alison Anderson and Central Land Council delegates.

Territory Chief Minister Clare Martin yesterday ruled out a High Court challenge to Federal Government plans to build a nuclear waste facility in the Territory.

"It is disappointing that our legal advice has ruled out the option of a challenge against Federal Government legislation that tramples on the rights of Territorians," she said.

Ms Martin said CLP senator Nigel Scullion would have the deciding vote on whether "we will have this dump forced on us".

The Territory delegation visited Sydney's Lucas Heights reactor to stage a protest against the proposed facility yesterday.

As part of the visit, Mr Stirling will present a petition of 9000 signatures opposing the radioactive waste facility to Territory CLP Senator Nigel Scullion.

The Central Land Council (CLC), whose area covers the Harts Range and Mount Everard sites, bitterly oppose the nuclear waste facility.

CLC director David Ross said the delegation aimed to send a simple message.

"We're making the point that people in Central Australia do not want a nuclear waste dump," Mr Ross said. "That's basically what we're letting the Government and the world know."

Mr Stirling said the Federal Government's decision to site the radioactive waste facility in the NT was based on politics, not science.

"We have a very clear responsibility on us to protect the interests of our constituents who don't understand any of this stuff," he said.

Mr Stirling said Lucas Heights was a far more secure site, much closer to major hospitals and security personnel, and waste would not have to be transported thousands of kilometres to get there.

But in contrast to the Central Land Council, the Northern Land Council has offered to negotiate with the Federal Government on possible sites for a waste facility on their land.

Federal Science Minister Brendan Nelson has said he would consider the NLC's proposal if traditional owners agreed.
