Napandee nuclear waste plan futile and unnecessary, as it lacks adequate knowledge of radionuclides involved

From the AINS Group (a multi-discipline engineering consultancy specialised in nuclear waste management services, Finland)

“… it is quite unlikely that Napandee could ever be commissioned by the regulatory body

Nonetheless the selection of a site would need a thorough safety assessment that includes climatic and groundwater conditions, rock stability, host rock composition, and the amounts and nature of the hazards of the waste (i.e. the radionuclide inventory). AS said before the AECOM report is not enough to demonstrate or ensure the safety of the site and the post closure monitoring for 300 years may also be an issue.

Final remarks. Knowledge of the inventory and mobility of the radionuclides in the wastes must be the first step in determining how and where the wastes should be stored and disposed of permanently.

Without this, it is not possible to even consider or decide the conditions or attributes of the waste management location and the manner of storage and disposal, and this will, or should be, the prime consideration in the licensing process.

This does not seem to have been done with the Kimba location and the nature of its facility and hence its selection and subsequent plans may prove to be futile and unnecessary….”

ANSTO has been completely disingenuous in communicating to Kimba community about radioactive waste levels

Three internationally renowned nuclear science academic and research institutions from overseas have tried to find out the inventory of the radionuclides of the re-processed nuclear waste at Lucas Heights which is to be placed in aboveground storage at Napandee near Kimba

The reason is that this would help – but not definitively – to determine the true level of that waste which ANSTO claims is intermediate level but France as the re-processing country classifies it as high-level waste.

All attempts to get this information have proved unsuccessful and the three institutions quite independently of each other believe that the information was deliberately withheld from them as it was probably realised that it could be used in some form to reclassify the intermediate level waste held at Lucas Heights.

However the radionuclides for the low level waste are readily available on ANSTO’s website.

Is this believable?

Should this be correct then it means that ANSTO has been completely
deceptive and disingenuous in its public disclosures particularly with regard to the Kimba community and all further attempts or actions to establish the national facility at Napandee should cease immediately

A radionuclide (radioactive nuclide, radioisotope or radioactive
isotope) is an atom that has excess nuclear energy, making it unstable.
This excess energy can be used in one of three ways: emitted from the
nucleus as gamma radiation; transferred to one of its electrons to
release it as a conversion electron; or used to create and emit a new
particle (alpha particle or beta particle) from the nucleus. During those
processes, the radionuclide is said to undergo radioactive decay.

Australia must plan for permanent disposal of Lucas Heights nuclear waste, not hurriedly transfer it to Kimba “temporarily”

Senator Sarah Hanson-Young, No Nuclear Waste Dump Anywhere in South Australia, 1 July 20, 

There has NEVER been an assessment or inquiry into the disposal pathway for intermediate-level nuclear waste for Australia.

ARPANSA has out on the record that there is NO urgency or safety concerns with the current storage at Lucas Heigts — then my questions is —- why move this intermediate-level waste before establishing long term plan for the disposal? Wouldn’t it make more sense? Otherwise we will be just double handling and risking the ILW to become potentially stranded at Kimba.
