"Most importantly, the political costs of going nuclear would be detrimental to Ukraine. The subsequent economic costs would also be huge," she added.

At the beginning of September, Ukrainian Prime Minister Arseniy Yatsenyuk said that Ukraine had decided to construct new nuclear facilities on its territory. Ukrainian Defense Minister Valery Geletey also said that the country plans to revise its non-nuclear status and thus protect itself from further attempts to violate its sovereignty.

Various international experts, however, questioned the above statements.

"Indeed, Ukraine does not have the capability to enrich uranium… It does not have reactors that are designed to produce weapons-grade plutonium and does not have the capability to process spent fuel," Senior Fellow at the Vienna Center for Disarmament and Non-Proliferation, Nikolai Sokov told RIA Novosti.

Sokov argued that nuclear weapons production in Ukraine is possible in theory, but in reality it would take a lot of time and money, which Ukraine does not have.

"All this can be done, in theory. I do not know how long, 10 years or 5; no serious expert will give an estimate, I suppose. Of greater consequence are two facts. First, this will require massive resources, financial first of all. A weapons program requires a large-scale experimental effort and then industrial construction. It does not have these resources and there will be no international assistance, I cannot imagine any bona fide state giving Ukraine the money to design and produce nuclear weapons," Sokov explained.

Sokov also added that no one wants another nuclear state and that the West will strongly oppose Ukraine's initiative, and highlighted that the statements made by the Ukrainian government are highly unprofessional.

"Nuclear weapons do not have a role in the ongoing crisis (except perhaps in a very remote, indirect way, which can be disregarded for all practical purposes). The talk about nuclear weapons that we hear from Ukraine these days is ill-advised, highly unprofessional …It actually discredits the Ukrainian government, nothing else," Sokov concluded.
