US Ability To Identify Source of Nuclear Weapons Decays 139

Hugh Pickens writes "The NY Times covers a report released by the National Research Council, which says the ability of the US to identify the source of a nuclear weapon used in a terrorist attack is fragile and eroding. The goals of the highly specialized detective work, known as nuclear attribution, is to clarify options for retaliation and to deter terrorists by letting them know that nuclear devices have fingerprints that atomic specialists can find and trace. 'Although US nuclear forensics capabilities are substantial and can be improved, right now they are fragile, under-resourced and, in some respects, deteriorating,' the report warns. 'Without strong leadership, careful planning and additional funds, these capabilities will decline.' The report calls on the federal government to take steps to strengthen its forensic capabilities and argues for the necessity of better planning, more robust budgets, clearer lines of authority and more realistic exercises."

    If a nuke goes off in a US city, we have an excuse for stalling on identifying who's responsible while politicians have a knee-jerk reaction and send US soldiers (or missiles, or UAV's) off on another enormously profitable [wikipedia.org] foreign adventure. And if it turns out they're wrong, we can blame it on anonymous technicians with "decaying skills".

      I wonder if you realize how right you are about the way the USA does things. From the summary:

      Although US nuclear forensics capabilities are substantial and can be improved, right now they are fragile, under-resourced and, in some respects, deteriorating,' the report warns.

      You know what else is fragile, under-resourced, and in many respects deteriorating? Our willingness to examine the connection between meddling in the affairs of soverign nations and their more radical factions' desire to go to extremes in order to attack us.

      For those who feel inclined to speak about this without having done any research (like that stops anyone these days), I'll sum it up briefly. The USA has a habit of using its intelligence services to overthrow democratically elected officials in foreign countries and usually replaces them with dictators more favorable to its economic interests. Iran during the 1950s is a good example, though only one of many. Do a little research and it is easy enough to come up with several examples of this behavior.

      Does anyone plan to argue that this does not constitute provocation in the eyes of those who suffer because of this practice? Yes, the way they retaliate is inhuman and reprehensible, particularly when they go after civilians. I fully agree with that. What I reject is the notion that "they hate us because of our freedoms". I think it's more like, they hate us because they want to be left alone. If that's the case, and if our goal is to end this sort of terrorism, our first responsibility is to end the practices of ours that encourage it. Then we are in a better position to go after the people who persist and come up with better ways to deter them.

    This is hardly rocket science. You get a sample from each reactor and perform an AMS* run on it. This gives you a fingerprint for that reactor. You get a sample from a nuclear weapon (pre-detonation or post-detonation) or fallout from debris (as in the case of Chernobyl) and perform an AMS* run on that.

    *You can also look for specific gamma energies.

    My A-Level computer science project could take the masses or energies and correctly infer which isotopes were present, in what ratios, and which reactor the sample likely came from. It double-checked by looking for daughter isotopes (decay products), since there are isotopes that look similar but follow different decay paths. I wrote that in less than a year in Turbo Pascal for the IBM PC.

    And the US Government is now saying that all of its nuclear labs combined can't either write their own frigging version, don't have the books I worked from, and don't have any AMS equipment to collect fresh data as needed?

        Every reactor produces unique isotopes. It's an absolutely unique fingerprint. It will be present in the plutonium (unless you are suggesting that someone is going to refine plutonium to near 100%) and has been used for decades. Air monitors during the cold war would harvest particles of radioactive debris from surface testing, permitting identification of which reactor the material was from.

        Almost nobody actually makes a pure uranium bomb. Horribly inefficient stuff. You need a lot of it to do anything, which immediately makes missiles impractical. Even if you did use uranium, the impurities would give away which mine it came from. Again, that is unique.

        They would be able to tell that a given sample was from a fast-breeder reactor, they'd also be able to tell that it was not one they'd got data for and they'd probably be able to tell which uranium mine the ore was from (there aren't many and no more are likely to be discovered at any depth we have the technology to operate at at this time). Since the fingerprint is unique, and since radioactive waste is awfully hard to get rid of subtly, it would be extremely quick and easy to find where the reactor was.

        An example of just how hard it is to hide these kinds of signatures -- the Russian who was poisoned by Polonium in London some years back. They can identify not only which reactor but which reactor vessel that Polonium came from. And that was with a very very trace sample. (As I recall, it was identified within a few hours of it being established Polonium was used.) Polonium has a half-life of 138.376 days. Since Britain closed Daresbury's 20MeV tandem accelerator, the options for doing a high-resolution run would have been limited, but they would certainly have been able to tell to within a day or two when the Polonium had been produced.

        THAT is the kind of fingerprinting that can be done. Hell, even with my A-Level project software, I was able to isolate almost every radioisotope in the Chernobyl fallout from just the gamma signatures and no AMS at all. (Every radioisotope not only has a unique mass, it also has a unique energy signature.)

        What would it take to get a sample for analyzing? Well, you get a bucket that you can open and close at both ends. You lower it into the water and take a sample. There won't be much plutonium or uranium floating near the surface, but there'll be enough even a few feet below to analyze. Back in 1978, that's how most of the research on the nuclear waste in the Irish Sea was done - with buckets, string, a dinghy and someone to keep look-out. Nothing fancier was needed and the results were staggeringly good. An actual core sample from the radioactive sludge would not have given you better results.

        The thing is, it's almost impossible for a reactor to not release enough waste for it to be (a) identified as a nuclear reactor, and (b) listed alongside its radioisotope signature. No country - USA and Russia included - has ever successfully hidden a reactor. At least, not for more than about a week. And the kit needed by a radiochemist to do any serious work is virtually nothing. At the time of Chernobyl, it was possible to take a mobile lab up to any farm in the Cumbrian hills and do studies of soil, lichen and sheep. If the US Navy can't fit such a lab into a small manned submersible or even an ROV, it's their own damn fault.

        • Not to nitpick, but the US government hides nuclear reactors all the time, in the form of Ohio-class ballistic missile submarines. However, the naval reactors on these vessels are in no way optimized for production of weapons-grade fissile material.

        • Hiding a reactor is pretty easy if the cooling loop is closed. What is not easy is hiding reprocessing.

Is it all a con? could it be replaced by a single teenaged student?

        Well, duh, obviously not. And therefore the claim that the ability to fingerprint fissile material is going away (as per the original article) is highly suspect at best, blatantly false at most likely. The skills are too damn simple. This is the usual scaremongering in an effort to bolster spending for weapons programs at a time when they may well get cutbacks.

      I suspect what they are saying is they need someone to collect those reference samples from certain 3rd world nuclear research programs.

      I expect what they mean by "decaying" is that the people who know how to do this analysis are dead and/or retiring.

      It's not a high-demand skill, after all (thankfully).

    First. we nuke all the commies. Thirdly. we nuke all the arabs. Seconded. we go get the oil . Teh plan is ideal.

    'Although US nuclear forensics capabilities are substantial and can be improved, right now they are fragile, under-resourced and, in some respects, deteriorating,'

    Fifteen years ago they had full capabilities, but only five years later their capacity was cut in half. Then, in 2005 they found that their capabilities were down to 25%. Today they are working at 12.5% effectiveness. At this point their capabilities are so degraded they have no idea what will be left in 2015.
    • The real question is, what is the decay product and where is all that radiation being vented?

    I'm no physicist, but the first thing that came to mind--without having any idea how they actually track this stuff--is doping.

    One would think that the places that produced this stuff would automatically fingerprint it by doping the material with rare elements, stuff that can only be produced in expensive labs or the nuclear plants themselves--such as Neptunium and Protactinium. Just enough of the elements, and in proportions specific to the place of origin, to ID the source of the product.

    Whether or not this stuff would be intact and usable for identification purposes after a detonation, no idea, but it would at least allow for confirmation-of-source on materials before they are actually incorporated into a device. And, lets face it, this is the time we want to be identifying sources--not when we are taking ground-zero samples.

      That's great if you control all the reactors. In the case of a nuclear attack on the US, I rather suspect that the source of the fissionable material would not be a US-based reactor. You'd need the IAEA to set up a register of signatures and conduct checks on all reactors to ensure that they're being applied correctly. (And that still ignores the unknown reactors, although really there's not much anyone can do about that).

      Look at your history books, specifically all the regimes supported by the U.S. for the last 50 years, a great majority of them are no longer our allies, just our enemies. What does that tell you about American Foreign Policy?

  • The implication is that a large part of the deterrent is the belief that the US can determine exactly where the nuke came from, and reply in kind. By announcing that that ability is decaying, that deterrent is completely undermined.

    While obviously it's better if we can actually do what we say we can, it's the belief that we can that (theoretically) keeps people in check.
