Australian news, and some related international items

Legislative and regulatory obstacles, highly dangerous wastes – Kimba nuclear dump is still an uncertain project.

no point moving intermediate waste from its temporary storage in Lucas Heights, to temporary storage in Napandee.

3 reasons the announcement to dump radioactive waste in South Australia is extremely premature , The Conversation, Ian Lowe, Emeritus Professor, School of Science, Griffith University    Prof. Ian Lowe was for twelve years a member of the Radiation Health and Safety Advisory Council, which advises the regulator ARPANSA.   1 Dec 21,

The site, Napandee, comprises 211 hectares of government-acquired land, with radioactive waste set to be stored for over 100 years in deep trenches.

Radioactive waste is extremely hazardous to people and the environment. It emits radiation, which can pollute water, kill wildlife and cause a number of deadly human health issues such as cancer. Even waste with low potency levels needs to be stored away for centuries, so the community should be assured the repository is well designed and properly managed.

While Pitt is celebrating what he regards as a resolution, there are three reasons this announcement is premature……………

1. Legislative and regulatory hurdles

Twenty years ago, The Olsen government of SA passed legislation to prevent radioactive waste being brought into the state. When the Howard government proposed storing radioactive waste in the state soon after, the subsequent Rann government strengthened that legislation.

This means the new proposal will require the current SA government to repeal or amend the current law. This will be difficult, as Premier Steven Marshall runs a minority government and, with an MP defecting in October, he’s likely to struggle to get the support he needs.

There is also a regulatory hurdle. A proposal such as this needs the approval of the regulator, the Australian Radiation Protection And Nuclear Safety Authority (ARPANSA), which will assess the proposal to determine whether it ensures the safety of people and the natural environment.

ARPANSA took the previous proposal by the Howard government very seriously. The process included public hearings at which the Director of ARPANSA was assisted by two scientists – I was one and the other was a Canadian expert in radioactive waste management.

It became clear in the assessment process that the federal government had made no attempt to calculate the risk of transporting radioactive waste from the various sites where it’s now stored to the more secure centralised facility. It simply asserted that the risk was minimal.

ARPANSA was not impressed by this data-free approach. Faced with opposition by the state government and questions raised by the regulator, the federal government withdrew the proposal.

2. The waste is more dangerous

The second serious hurdle is that “intermediate level” waste from a nuclear reactor temporarily stored at Lucas Heights will be sent there.

The new Napandee facility will mostly store the comparatively benign “low-level waste”. This includes residues from nuclear medicine, scientific research and industrial applications. Once buried in deep trenches, this poses relatively little risk to humans or wildlife.

Intermediate level waste is much nastier and demands much greater levels of security. It contains long-lived radioactive isotopes that need to be isolated and contained for periods of thousands of years – effectively permanent disposal. This is generally seen as requiring engineered underground containment facilities, rather than the near-surface repositories used for low-level waste.

No such facility to safely, and permanently, house this waste has been built in Australia, and the regulator will undoubtedly require assurances it could be safely constructed and managed.

It will also be much more difficult to justify transporting this waste along the roads of three states, given it’s now securely held at Lucas Heights. Transporting nuclear waste comes with risks of accidents or possible theft by terrorists of the dangerous material.

There seems to be no point moving intermediate waste from its temporary storage in Lucas Heights, to temporary storage in Napandee.

The third hurdle for the proposal is the opposition of the Barngarla Traditional Owners, who have made clear they do not support the proposal for radioactive waste to be stored on their land.

After the consultation process in SA, a ballot showed 60% of the local residents supported the proposal. But the the Barngarla people say they have not been included in consultations.

In previous decades, our governments have ridden roughshod over the wishes of Traditional Owners and imposed developments they did not want. Today, the Australian public is generally more respectful of the wishes of Traditional Owners.

There will certainly be legal challenges to the government’s scheme. But even if the Barngarla people don’t have the law on their side, they have the moral authority. It will be politically difficult for any government to justify going ahead with a scheme that is totally opposed by the relevant Indigenous group.
