U.S. Plans to Tighten Nuclear Power Plant Security

CDMA_Demo writes "The 103 nuclear reactors running in USA can voluntarily agree to follow a new 15 page update to a 1996 regulatory guide. The update notes possibility of "unauthorized, undesirable, and unsafe intrusions", and recommends measures aginst such activities. It also recommends such facilities to be cut off from external networks: "Remote access...[that may pose a potential security risk]...should not be implemented". The Slammer worm in 2001 managed to bring down the network at Ohio's David-Besse nuclear plant and concerns kept growing at the United Nations' International Atomic Energy Agency (IAEA)."

      Years ago I did some research on Chernobyl accident and remember reading that there was a concrete containment shell, but it blew up with the reactor. Most of the sites I now found by googling repeat the statement that there was no containment shell, but at least this site claims the opposite: "2. Despite official statements made in the U.S. right after the accident, Chernobyl No. 4 did have a reinforced-concrete containment--one that was installed in 1980. Whether the shell was comparable to what you'd find on the average U.S. reactor isn't clear. In any event, Chernobyl No. 4's outer shell was probably breached by a powerful hydrogen explosion, which, you may recall, was the greatest fear in the days following the Three Mile Island accident. The power released in such an explosion could be great enough to destroy any existing reactor's containment."

      Sorry, your source is wrong. There are a lot of sources with inaccuracies about the Chernobyl incident due to the USSR's lack of glastnos. I've done a great deal of research on the accident and the RMBK 1000 design used in Unit 4. There was never any containment structure as it was seen as a waste of money since the Soviet government made sure that the people believed in the design's infallibility as they've never heard of any problems with the plant including the positive void coefficient causing the reactor to run away(Again due to the lack of glastnos, Even other units in the same power plant experienced problems that would've probably made a huge difference if the crew of Unit 4 were allowed to know about it). One thing about shell is that it doesn't have to mean containment. Perhaps this author misunderstood the design and is referring to the thick concrete biological shield(Thick, but not that thick. Thick enough to do its job of shielding from radiation but could not withstand the pressure build up). One thing I've noticed was that even the books that had ridiculously wrong accounts of what happened at Chernobyl(Again, due to the lack of glastnos as the government wouldn't let them publish anything that defied the infallibility of the Communist regime) admitted the lack of a containment structure which is only because they still insisted in their writings that the lack of a containment structure in the RMBK design was fine since the RBMK was so safe(Yes, they wrote this AFTER Chernobyl).

      After skimming that site you gave, I'd have to say that they haven't done their research. The claim that the accident was caused entirely by human errors is just plain wrong. The accident was caused for the most part by the fataly poor design of the RBMK reactor and that design combined with the Soviet way of running the nuclear industry made an accident inevidable anyone. It's a absolute miracle it didn't happen sooner! The explosion happened when someone hit the AZ button. That's the EMERGENCY SHUTDOWN button. This caused the accident because all the control rods were dropped at once which due to a huge design flaw pushed neutron absorbing and reactor cooling water out of the core allowing for a heat surge great enough to twist the channels to prevent the rods from descending further and allowing the explosion. Tell me, if an explosion happens when you hit an emergency shutdown system, whose fault is it? As far as the operators knew, the AZ button should've been a completely safe way to stop that reactor. The point of an emergency system is to be a failsafe way to bail from a bad situation, to prevent disaster. It was due to the poor design of the control rods that the AZ button instead caused an incredible surge. There's a book that explains all the alleged violations of the operators and how many of the supposed terrible one didn't really contribute to the accident. Alot of the violations weren't because the operators were rouges but really normal in Soviet power plants. The truly significant violation was the removal of practically all inserted control rods which a guideline disallowed(AFTER Chernobyl!) and was protested by the operators but ordered by the Deputy Chief Engineer.

      "Within half a minute they realized that the reactor was running out of control, and they tried to shut it down by dropping all the control rods into the core. Probably because the fuel rods had already overheated and distorted, some of the control rods failed to go all the way into place."

      Wrong. Definate lack of research. This statement implies that the rods simply never made it into the core and it was the already present conditions from before the AZ button that caused the explosion. Wrong. It was the conditions created by the entrance of all those rods into the core because the graphite at the end of the rods did make it inside to make conditions far worse.

    This is anecdotal, but minorly noteworthy - My mom used to work for the company that owned and operated Three Mile Island - the (physical) security was intense: the perimeter was ringed by towers manned by security offers with rifles and a 'no warning shot' policy - you approached the perimeter from an undesignated direction and you got shot, period.

    I still have one of the security force's hats, says "TMI Rapid Response Team" and has a crosshairs in the middle.

    The Main Plant Computer System at my nuke plant doesn't actually do anything but monitor system parameters. It cannot cause the plant to do anything. It's very handy, but not vital to safety at all. I'd imagine other plants are set up the same.

    Solid state logic systems do run the safety systems, but there's no way to interface with them besides the physical controls that are directly connected to them.

    Would someone like to explain to me why the systems (assumingly CRITICAL systems) at a NUCLEAR POWER PLANT are connected to the Internet ... They aren't. ... I don't understand why so many people swallow the intimations of the inflamatory headlines.

    But they are. You need to read the fine Security Focus article again, but I'll quote the worst parts for you.

    The T1 line, investigators later found, was one of multiple ingresses into Davis-Besse's business network ... From the business network, the worm [slammer] spread to the plant network, where it found purchase in at least one unpatched Windows server. ... Users noticed slow performance on Davis-Besse's business network at 9:00 a.m. ... At 4:50 p.m., the congestion created by the worm's scanning crashed the plant's computerized display panel, called the Safety Parameter Display System. An SPDS monitors the most crucial safety indicators at a plant, like coolant systems, core temperature sensors, and external radiation sensors. Many of those continue to require careful monitoring even while a plant is offline, ... At 5:13 p.m. ... the "Plant Process Computer" crashed. Both systems had redundant analog backups that were unaffected by the worm, but, "The unavailability of the SPDS and the PPC was burdensome on the operators," notes the March advisory.

    That's not a headline, that's a detailed technical report.

    Having worked at a plant, I can say that the picture is accurate. Winblows servers have snuck into plant networks and they are awful pieces of shit that have no place there. While they are not in direct control, they can cause trouble if you depend on them to make decisions. A box that blows your network can cause even more problems because it blinds you to what might be critical information and communications. A back up you are not staffed to use is not a backup.

    It's not just power plants and operators at risk. Winblows born network congestion is also implicated in the huge 2003 power outage that killed people. When hospitals, home medical equipment, EMS, stoplights, and other things we take for granted lose power, people die.

    From a sidebar in the January issure of Forbes magazine.

    1. Terrorists storm a reactor and try to steal uranium or plutonium to make bombs.

    Not likely. Assuming attackers could shoot their way past the beefed-up phalanx of armed guards, traffic barriers and guard towers that now surround every nuclear plant, they'd still have to fight their way into the reactor building through multiple levels of remote-activated blast doors--where access requires the right key card and palm print--to get to the spent-fuel pond, says Michael Wallace, president of Constellation Energy's generation group, which operates five nuclear reactors. The pond is where highly radioactive used fuel sits in 14-foot-long stainless steel assemblies cooling under 40 feet of water. Terrorists couldn't just grab this stuff and run because, unshielded, it gives off a lethal dose of radiation in less than a minute. To avoid exposure, terrorists would have to force workers to use a giant crane inside the reactor to load the assemblies into huge transfer casks, then open the mammoth doors of the reactor building and use another crane to lift the cask onto a waiting truck--all the while being shot at by the National Guard.

    And While we are at it, How about crashing a plane into the reactor?

    2. Terrorists crash a plane into a reactor, leading to overheating and a meltdown.

    Even less likely. Assume that terrorists could get past tightened airport security and fight off passengers to get through new, improved cockpit doors and take control of a plane. Even then they'd have to crash the jet directly into a reactor to have any chance of breaking containment. In 2002 the Electric Power Research Institute performed a $1 million computer simulation to assess such a risk. Conclusion: A direct hit from a 450,000-pound Boeing 767 flying low to the ground at 350mph would ruin a plant's ability to make electricity but not break the reactor's cement shield. Reason: A reactor, smaller in profile than the Pentagon or World Trade Center, would not absorb the full force of the plane's impact. And, for all the force behind it, a plane, built of aluminum and titanium, has far less mass than the 20-foot-thick steel-and-concrete sarcophagus enclosing a nuclear reactor. It would be like dropping a watermelon on a fire hydrant from 100 feet.
