NRC removing cyber security from dead dsan Onofre nuclear station – but that’s still dangerous

NBC 20th March 2018, With reports of American power plants across the country having their
systems accessed by hackers, one group of scientists are calling out the
Nuclear Regulatory Commission (NRC) and Southern California Edison for
their recent decision to remove enhanced cyber-security systems at the San
Onofre Nuclear Generating Station.

“It defies logic and it’s not
technically sound,” Dr. Edwin Lyman, a Nuclear Scientist with the Union
of Concerned Scientists told NBC 7 Investigates. Scientists like Lyman
point to a report released just last week as evidence for power plant
operators to take cyber-security more seriously, even at closed power
plants like San Onofre. https://www.nbcsandiego.com/news/local/Scientists-Fear-Cyber-Security-Reduction-Could-Make-San-Onofre-A-Target-for-Hackers-477447193.html

The climate change threat to nuclear power

By Natalie Kopytko “…………The final problem is droughts, which climate models predict will become longer and larger. Legal battles have already been fought in the US over scarce water resources in regions with nuclear power plants, including the Catawba river basin in the Carolinas and the Apalachicola/Chattahoochee/Flint river basin in Georgia, Florida and Alabama. These battles show us that adapting our systems – including nuclear power – to a reduced supply of water will not be easy.

The International Atomic Energy Agency advises the nuclear industry to build power plants to last for 100 years. Given that climate models don’t agree on what to expect within this time period, it is not at all clear how this can be achieved.

New reactors could use dry or hybrid systems with lower water requirements, but the costs of running these systems are likely to be prohibitive. Considering nuclear power plants already have problems with construction cost overruns, any additional costs are likely to meet resistance.

What is to be done? Most forms of energy generation are vulnerable in some way to the effects of climate change, and the fact that nuclear power is among them is yet another argument against a wholesale shift towards this source of energy.

The bottom line is that if nuclear power is to be used to mitigate the effects of climate change, it must also be capable of adapting to them. There are serious doubts that it can. more https://www.newscientist.com/article/mg21028138-200-the-climate-change-threat-to-nuclear-power/
