Some months ago it became known that the German Intelligence Service (Bundesnachrichtendienst - BND) was spying on Turkey. Turkey's political leadership was none too happy. Yet the BND has good reasons to keep a watchful eye on Ankara. It is not only the crises in Iraq and Syria, drug-smuggling, people-trafficking and the activities of the PKK that make Turkey a legitimate target for German intelligence. For quite some time, evidence is mounting that Ankara is trying to acquire nuclear weapons.
Over the past two decades, discussions within the nuclear community about emerging nuclear powers always centred on the "usual suspects": Iran, Saudi Arabia, Brazil, Egypt, Japan, South Korea and Turkey. Not surprisingly, opinions as to the likelihood of a military nuclear program differed. In the case of Iran, for example, the evidence appeared solid. By contrast, the case of Turkey was built on vague indications.
This list of likely nuclear aspirants has not changed since, yet the likelihood of a Turkish nuclear weapons program has increased dramatically. Simply put: the Western intelligence community now largely agrees that Turkey is working both on nuclear weapon systems and on their means of delivery. Iran is the model to emulate. Consequently, Turkey has started a large-scale civilian nuclear program, justified by the country's urgent energy needs. In 2011, Turkey concluded a $20bn contract with the Russian company ROSATOM on a large reactor complex. Two years later, a similar agreement was concluded with a Japanese-French consortium, this time over $22bn. President Erdogan also announced yet another power plant, to be built entirely by indigenous personnel.
So far, so good, one might say. After all, nuclear energy seems like a sensible option to at least partially meet Turkey's demand for affordable energy. However, a thorough analysis of the contracts reveals that these projects are not just about improving Turkey's energy supply. Turkey has also consciously opened the door to a military nuclear option.
Proposals for constructing a light-water reactor usually consist not just of a commitment to build the plant according to agreed specifications and timelines, but also commitments to run the project for sixty years, to provide the required low enriched uranium and to take back the spent fuel rods. Such offers were put forward by both Rosatom and the Japanese-French consortium. However, in both cases, Turkey insisted that the deal would neither include the provision of uranium nor the return of the spent fuel rods. Ankara wanted to deal with this matter separately at a later stage. Turkey never provided an explanation for this decision. However, the intention behind this unusual maneuvering is not difficult to fathom. Turkey wants to maintain the option to run the reactors with its own low enriched uranium and to reprocess the spent fuel rods itself. This, in turn, means that Turkey intends to enrich uranium, at least to a low level.
And there is more. The option to provide low enriched uranium to currently eight agreed reactors—Turkey is planning twenty-three projects in total—indicates the scope of Turkey’s envisioned enrichment effort. The path that Turkey wants to take is clear: to follow in Iran’s footsteps. According to President Rouhani, Iran wants to build sixteen reactors by 2030, which are supposed to be powered by indigenously enriched uranium, although much of this low enriched uranium is earmarked for high enrichment and thus for the production of weapons-grade fuel. Of course, Turkey vehemently denies any intention to enrich uranium. However, Turkey has declared on many occasions that it will always insist on its “rights” deriving from the Nuclear Non-Proliferation Treaty (NPT), and that it regards enrichment for peaceful use as perfectly legal. That the Turkish government is at pains to justify its rejection of an external supply of low enriched uranium while not admitting a national interest in enrichment was illustrated by a statement made by the Turkish Minister for Energy, Taner Yildiz, in January 2014. Yildiz argued that the refusal to contractually settle the uranium supply with the aforementioned companies was due to Turkey’s desire to understand the full nuclear fuel cycle. Not only does Yildiz’ explanation appear weak; Turkey’s declaratory nuclear policy also seems to follow the path taken by Iran: one only admits what in light of the facts can no longer be denied.
Turkey’s motives for rejecting the continuous uranium supply by its Russian and Japanese-French business partners may appear dubious; its rejection to return the spent fuel rods to the supplying countries is outright disastrous, as it allows for only one conclusion: Turkey is bent on producing plutonium for making weapons. While reprocessing would indeed allow the reuse of the spent uranium, such an option is merely theoretical, since fuel rods made from reprocessed material are far more expensive than those made from “new” uranium. It is for this reason that reprocessing of spent uranium is hardly being conducted anymore.
With its rejection to return the spent fuel rods, Turkey is embarking on the pathway to the bomb. The common counterargument, according to which the separation of the “dirty” plutonium would require a sophisticated reprocessing plant that currently does not exist in Turkey, remains unconvincing. Studies have shown that such a plant can be built within half a year and would be the size of a regular office building. Moreover, the widespread belief that in order to build a nuclear weapon, one requires weapons-grade plutonium with an impurity level of at most 7 percent, is long obsolete. Already in 1945, General Groves, the leader of the “Manhattan Project,” noted that due to the shortage of pure plutonium, the United States would soon be forced to use material with an impurity level of up to 20 percent. In 1962, the United States detonated a plutonium bomb in Nevada that had an impurity level of 23 percent. Finally, if the fuel rods of a light water reactor do not remain inside the reactor for several years, which is the economically viable option, but are removed after only six to twelve months, one ends up with weapons-grade plutonium. The Iranian reactor Bushehr offers a telling example. If the reactor were powered down after eight months and the fuel rods removed, Iran would own 150 kilogrammes of plutonium with an impurity level of only 10 percent—the equivalent of twenty-five Nagasaki-category bombs. In short, the weaponization of plutonium has many facets.
The assumption that Turkey is aiming for nuclear weapons is also supported by the country’s activities towards creating the entire nuclear fuel cycle. As has been revealed by a well-connected information service, German intelligence reported that as far back as May 2010, Prime Minister Erdogan had demanded to secretly start preparing for the construction of sites to enrich uranium. Accordingly, Turkey has started to produce Yellowcake, a chemically compressed uranium ore. Yellowcake is converted to gas, which is then enriched in centrifuges. To date, nothing is publicly known about a conversion plant in Turkey, yet according to the BND, Turkey is already in possession of enriched uranium originating from a former Soviet republic and smuggled via Kosovo and Bosnia and Herzegovina with the help of the Mafia. It would not come as a surprise if Turkey already had centrifuges to enrich uranium. After all, Turkey was involved in the activities of Pakistani nuclear smuggler Abdul Qadeer Khan, who between 1987 and 2002 sold thousands of centrifuges to Iran, North Korea and Libya. The electronics of these centrifuges came from Turkey. Khan had even contemplated moving his entire illegal production capacity of centrifuges to Turkey. In 1998, then Pakistani prime minister Nawaz Sharif offered Turkey a “nuclear partnership” on nuclear research. Moreover, there is still an organic partnership between both countries dating back to Turkey’s support for Pakistan’s nuclear program. Back then, many of the components that Pakistan could not acquire openly were shipped via Turkey to Pakistan. With this backdrop, it does not come as a surprise when intelligence services report that to this day there is a dynamic scientific exchange between both countries.
