Iran and Nuclear Weapons: The Problem
6 September 2009
The Iranian nuclear programme has been a source of continuing concern to the international community, and it ought to be of serious concern to us here in New Zealand. Notwithstanding claims to the contrary, it is clear that what Iran is doing, at more than twenty sites throughout that country, represents a clear danger to the security of the Middle East and the wider world, and, incidentally, to any prospect of holding the line on nuclear proliferation. It is, in fact, engaged in a comprehensive programme to obtain nuclear weapons and very little of this activity has any other plausible explanation.
The only exception to this generalisation is the Russian-built light-water reactor at Bushehr, on the Persian-Gulf coast. In so far as it represents, on Iran’s part, a genuine desire for civilian nuclear power, it is unobjectionable and of minimal proliferation significance. If it is run in the way originally envisaged, on the basis that Russia supplies fresh fuel, takes away spent fuel and holds or reprocesses it, it should not be seen as a threat. Even for an oil-rich country, it makes sense to replace oil-burning power generation by nuclear generation. It is kinder to the environment and it conserves a valuable but diminishing resource.
The problem is all the other things that Iran is doing. At various sites around the country it is operating ore purification and uranium enrichment facilities and building up the capability to produce weapons-grade plutonium in a dedicated reactor. In connection with the latter, the Iranian authorities are also constructing a reprocessing plant, through which it would be able to extract plutonium and make it available for weapons fabrication. According to exile groups, Iran also has at least one weapons research facility, concealed underground, on the edge of the Caspian Sea.
Some of these technologies are ‘dual-use’: that is to say they also have a legitimate use in the civilian nuclear fuel cycle. This applies particularly to uranium enrichment (with its thousands of spinning centrifuges), which is the basis of fuel fabrication for the most common type of civilian reactor. It also applies to reprocessing, which, in many places in the world, is used to extract further energy from civilian spent fuel. It should be noted here that the plutonium content of civilian spent fuel from the common kind of commercial ‘light water’ reactor is very different from that produced in a dedicated military production reactor. In the latter case, the plutonium in the spent fuel will typically contain more than 90% of the fissile isotope, plutonium-239, making it ‘weapons-grade’. By contrast civilian spent fuel will usually contain 60% or less of plutonium-239, making it practically unsuitable for weapon fabrication.
Enrichment and reprocessing make no economic sense in relation to Iran’s embryonic civilian nuclear power programme. As noted, Russia has undertaken to supply fresh fuel (in fact, the first lot has already been delivered) and any need for reprocessing is decades down the track (in any case Russia has promised to do this, too). In both cases, there are alternative suppliers of both services and in all cases the cost would be a fraction of what it would cost Iran to do it itself. It is as if your neighbour announced that he was expecting delivery of a new car and, in anticipation of that event, was already building a fully staffed workshop to service it. One could only think that there must be another reason for such pointless expense. To continue the analogy, it is not as if the neighbour was already the operator of a fleet of vehicles that would provide immediate work for the proposed facility. Iran has just one, relatively small reactor
In the case of Iranian nuclear activity, it is obvious what that other reason is. Iran is engaged in a covert nuclear weapons programme. The only question is, when is it likely to have sufficient fissile material (presumably, highly enriched uranium) to make a bomb, or bombs? Estimates vary on this, in part because there is some doubt that the IAEA and the various intelligence agencies are fully aware of what Iran is doing. Earlier this year, US intelligence reports suggested that this situation might be reached by 2013 but other sources talk of earlier dates.
The reason why this is of general concern stems from what recently re-elected Iranian President Ahmadinejad has being saying about relations with his neighbours (especially Israel) and about relations with the ‘West’ generally. Apart from repeated observations about ‘wiping Israel off the map’, Ahmadinejad has also spoken (in 2007) specifically about how he might use nuclear technology:
“Iran will place its nuclear technology at the service of those determined to confront the US and other Western countries.”
One interpretation of this cryptic comment is that Iran would supply fissile material to terrorists, who might construct a crude nuclear bomb, which they might attempt to smuggle into the US (or, elsewhere) inside a shipping container, as in the Tom Clancy novel. Generally, this is a scenario that has exercised many minds since 9/11 with always the question, where would the terrorists get the nuclear material? Even if the Iranian leadership is taken to be merely bluffing here, a nuclear capable Iran would raise the prospect of a nuclear arms race in the Middle East and must surely make Iran even more intractable in the matter of its support for terrorism. This is why various parties have declared the prospect of a nuclear capable Iran as quite unacceptable. The crucial question is what will they do about it?
