Nuclear Safety Push To Be Softened After US Objections

mdsolar writes with news that the U.S. objects to a proposal to amend the Convention on Nuclear Safety put forward by Switzerland. The United States looks set to succeed in watering down a proposal for tougher legal standards aimed at boosting global nuclear safety, according to senior diplomats. Diplomatic wrangling will come to a head at a 77-nation meeting in Vienna next month that threatens to expose divisions over required safety standards and the cost of meeting them, four years after the Fukushima disaster in Japan. Switzerland has put forward a proposal to amend the Convention on Nuclear Safety (CNS), arguing stricter standards could help avoid a repeat of Fukushima, where an earthquake and tsunami sparked triple nuclear meltdowns, forced more than 160,000 people to flee nearby towns and contaminated water, food and air.

    The first thing would be tougher rules for nuclear site selection.

    While it restricts the allowed area for a nuclear site, there'd be almost no additional cost for the site construction and maintenance (unless it's a really remote location). This would already help a lot.

    Correct me if I'm wrong, but wasn't fukushima's nuclear plant already breaking Japan's law? Why would then more regulation even help the problem? Enforcing current regulations on older plants should take priority over more red tape and bureaucracy.

      A big part of the Fukushima's problems were cultural. A Japanese tendency towards social order and not questioning superiors let bad decisions worsen the situation.

      Only reason it didn't go Chernobyl was the plant manager, Masao Yoshida, chose to disobey direct orders and continued to pump in sea water (his superiors told them to stop and pull out which would have led to a complete meltdown)

      What really worries people in Japan is that previously undiscovered problems keep coming to light at existing plants, now that proper checks are being done. Any trust that existed has proven to have been misplaced.

      To be fair, some of the issues could not have been discovered when the plants were built. Equipment to find fault lines like the ones discovered recently did not exist in the 1980s. That just makes it worse though, because it demonstrates how even now we are discovering new issues and improving our understanding of the environment.

      When the consequences of an accident are so severe being 99% sure it's okay isn't enough to gamble on. Of around 450 commercial electricity producing reactors 6 have melted down catastrophically. That's a 1.33% failure rate, and doesn't include all the other serious problems at nuclear plants. It's no wonder nuclear plants can't get commercial insurance.

      Mistakes were made, but the operators did what they could with what they had. Those in the nuclear industry don’t fault their actions. They were heroic. The Fukushima reactors *were* shut down safely. It's an automatic event during a loss of offsite power, and for some plants, a seismic event. All the rods inserted into the all the cores. There's nothing an operator can do to stop it. But, there is still a massive amount of decay heat that must be removed long term, on the order of 100s of MWs initially, then falling over the course of several months. The diesel generators and decay heat removal systems all worked properly in order to remove this heat. The isolation condensers (IC) (unit 1 only), and reactor core isolation cooling (RCIC) systems on the other units started and began maintaining water level in the reactor pressure vessels (RPV) and removing decay heat. There are numerous high pressure (> 400 psi) and low pressure ( 400 psi) water supply systems. RCIC is a high pressure steam driven turbine relying on steam from the RPV and DC power (batteries) to supply power for the valves. The isolation condensers are passive natural circulation heat exchangers. These two systems are designed to be used for short term cooling until the RPV pressure can be lowered to allow the low pressure systems to take over. The low pressures systems require AC power from either offsite or the diesel generators. 41 minutes after the shutdown, the tsunamis took out the diesel generators and the DC switchgear. This is where things went south. The operators ended up with no way to cool the cores. There was little they could do to combat it. Batteries were pulled out of cars to power DC valves. A portable generator was use to power some instrumentation. A fire truck was used to try to maintain water levels until a hydrogen explosion destroy the connections. All the while these guys were taking massive doses of radiation and with the knowledge that their families were likely dead.

      The problem is that no insurer will insure a nuclear plant, so governments have to take the liability on themselves. Essentially nuclear operators get subsidised free insurance, so where are normally a commercial insurer would require high standards the government has to and the government is vulnerable to lobbying (bribes) and other shenanigans.

    The Convention on Nuclear Safety (CNS) is a treaty-ish pile of broad and anti-specific foofy diplo-language. Its purpose is not to share or agree on a single iota of practical knowledge, though over time a tiny bit might creep into it. It exists to permit and encourage the ratification of itself by as many parties as possible, and in this, it is like those "bad luck if you do not forward me" chain letters.

    The Swiss proposal said in effect, stop all the music and implement every feature ever conceived to make new plant designs safer, to every existing plant. Somehow. Even if it is redundant and absurd. The whole kitchen sink. They cannot be bothered with specifics, that is not the game being played. Signing on to every broad recommendation would be a direct insult to our own NRC, which does not dabble in such diplomatic newspeak, preferring to assess actual risk, look at each site, mandate practical and specific engineering guidelines, evaluate what has been done.

    See INFCIRC/449 and Add.2 and Add.3 and Add.4 and Swiss Amendment.

    This stuff was written by people from another planet. It was probably leaked from Planet X which is orbiting with the Earth directly behind the Sun. Planet X is just like ours only its United Nations truly runs everything. That is why they send UFOs to abduct an engineer every now and then, to keep their shit from falling apart. Then we send one of our own (out of Hangar 19) to bring 'em back. Maybe we got the wrong one back, one of their 'senior diplomats' instead.

    In it you will find some vague things that sound like good ideas. You're supposed to imagine that this is a world where people do not apply common sense unless they are acting directly on the recommendations of a multi-national NGO.

    The compromise statement now says basically, "New nuclear power plants should be designed and constructed with the objective of preventing accidents, and minimizing off-site contamination in case of accidents. Reasonably achievable safety improvements identified at existing plants during... safety assessments should be oriented to these objectives and be implemented in a timely manner."

    Engineers should not be afraid to stand up and express their anger when they are insulted. This is an insult. We lose an essential part of our human self-respect and tenacity when insults like this go unanswered. Governance of the world should not be bestowed upon folks who cannot be bothered to delve into detail. Regardless, some people will be comforted by the mere presence of the CNS, they're the people who distrust corporations and their own government, to find solace in the flowery language of international diplomacy even though there is little substance in it.

    Basically, this organization-thing was spawned in 1994 and went to sleep. Fukushima woke it up, and they've been running in little circles ever since to come up with a timely response. The response has finally arrived and is on the table in early 2015. This is the kind of time frame you can expect if you pursue world governance.

      Actually we learned quite a bit more. When mark 1 reactors lose coolant flow to ultimate heat sink they have at least 3 failure modes that were not previously considered. Loss of ultimate heat sink can happen many ways so this lesson is important for currently operating mark 1 reactors. A flood, drought or any obstruction to intake pumps would have the same effect as loss of pump power. The real lesson was that these reactors do not handle these situations gracefully. Number 1 most likely melted through the control rod holes. Number 2 busted a big hole in its torus and number 3 was most likely a prompt criticality in the spent fuel pool after a melt down and hydrogen explosion. Oh and number 4 fuel pool caught fire. We also learnt that once you have a reactor with a fractured base lying below ground water (which by design these reactors are) it's really hard to stop continued flow of radioactive water into the adjoining river or ocean. These are all relevant to current Mark 1 and other reactors in the US and elsewhere. A rational response would have been to not relicence any of these reactors and move to phased shutdown of the Mk 1 fleet. Issues like embrittlement and small torus cannot be remedied by retrofitting. Also, the spent fuel fire and possible criticality should prompt a hurry up in the program to get fuel out of ponds and into casks.

    Not sure what exactly it was that got you riled up like that. Of course it is held in broad strokes, and of course it's the job of the national nuclear safety institutions to come up with, implement and oversee the guidelines and rules. It's the lowest common denominator everyone can (or should be able to) agree upon. That's how these things work.

    The amendment states:
    "Nuclear power plants shall be designed and constructed with the objectives of preventing accidents and, should an accident occur, mitigating its effects and avoiding radionuclides causing long-term off-site contamination. In order to identify and implement appropriate safety improvements, these objectives shall also be applied at existing plants."

    There's also a bit on the goal of the amendment: "Switzerland believes that making the principle of "avoiding off-site contamination" legally binding in the Convention would be a vital step towards improved global nuclear safety. ..."

    Sounds pretty reasonable to me. But then some existing plants would have to be reexamined and maybe even receive some upgrades to their safety measures. Which would affect somone's bottom line, and we can't have that, now can we?

Many people along the coast of Japan, well outside the Fukushima zone, are still struggling and displaced. They've lost loved ones and their homes. Many will not be able to rebuild in the same place as their old home, but the anti-nuke agenda driven assholes of the world gladly ignore that suffering because they see an opportunity to spread fear.

Do you trust those that are more driven by their agenda than human compassion? Try to find stories about those forgotten victims. It takes a little sifting and effort.
