Hi Andy,
Thanks for the post.
Thanks also to Steffen who enunciated the primary concern, which I would
have thought to be self evident but were mistaken, that such a facility,
by definition, would be made to be very secure and that floodlighting is
usually part and parcel of that.
So the news is as welcome as that of, say, news of plans for a night
time golf range or twenty-four hour open cut coal mine.
The Astronomical Society of New South Wales (ASNSW) owns the 107
acre property at Ilford and it is rare for an astronomy club anywhere
in the world to have possession of such an asset.
Considerable time, most of it voluntary, and money has been invested
in the property over the years and it has brought great enjoyment to
thousands of people who come for its primary asset of dark skies.
However, as visitors to Wiruna often note, over the past decades the
night skies there have been deteriorating with the increasing light
pollution, particularly in the direction toward Sydney.
Any additional sources of light pollution, particularly from a source so
close, would be disappointing to say the least and at those distances,
anecdotally, it is likely to be visible.
It is a double-edged sword. On the one had, if such a facility were built
nearby, observers would hope that its light pollution footprint would
be small. On the other hand, right-minded folk would hope that the facility
exercised best practice security. There are no shortage of people in the
world who would dearly love to get their hands on even small amounts
of low-grade nuclear waste. So if the facility was not engineered
with security floodlighting and the threat of lethal force, which seem
reasonable measures, most of us would be asking why not.
As I understand it, currently South Australian state law makes it illegal
to build or operate a nuclear waste storage facility. It might be one of the
reasons less remote locations are being considered.
