A Senate committee report into the proposed nuclear waste dump at Muckaty Station, north of Tennant Creek, has been delayed.

The committee was meant to present the report today but Northern Territory Senator Trish Crossin says it will not happen for at least another week as the committee continues its investigation.

Senator Crossin says the report is not looking at whether or not there should be a nuclear waste dump, but at the fairness of the proposed legislation.

"This was a committee that was looking at whether or not when this legislation goes through and the Federal Government decides to put a waste facility in this country whether this legislation provided a fair and proper process for all parties concerned," she said.
