Iran's nuclear power industry has been a subject of much controversy and international scrutiny in recent years. With one operating nuclear power reactor and another under construction, the country has been at the center of global discussions regarding its nuclear capabilities and intentions.
Construction on the second large Russian-designed unit at the Bushehr site began in November 2019, with plans for a third unit in the works. In addition to its nuclear power infrastructure, Iran also had a significant uranium enrichment program, which it had covertly developed over many years.
Under the Joint Comprehensive Plan of Action (JCPOA), Iran agreed to limit its enrichment activities and cease work on heavy water-related projects. However, the USA's withdrawal from the agreement in 2018 prompted Iran to resume enriching uranium, leading to tensions and international concerns about the country's nuclear ambitions.
In June 2025, the International Atomic Energy Agency declared Iran in breach of its non-proliferation obligations, prompting military actions from Israel targeting Iran's military and nuclear fuel cycle sites. The escalation of conflict further strained relations and raised fears of potential nuclear proliferation in the region.
By October 2025, Iran officially ended its commitment to the 2015 JCPOA, declaring all restrictions on its nuclear program null and void. This move signaled a significant shift in Iran's approach to nuclear power and raised alarm bells among the international community.
In March 2026, the USA and Israel launched a joint military campaign targeting Iran's nuclear fuel cycle sites once again, underscoring the ongoing tensions and security concerns surrounding Iran's nuclear activities.
Despite these challenges and controversies, Iran's nuclear power industry continues to operate, with one reactor generating 915 MWe of electricity and another 974 MWe unit under construction. The country's electricity sector relies heavily on natural gas, with nuclear power accounting for a small but significant portion of its generation mix.
With electricity demand growing at a rate of about 4% per year, Iran trades electricity with neighboring countries such as Afghanistan, Armenia, Azerbaijan, Iraq, Pakistan, Syria, Turkmenistan, and Turkey. The country's total generating capacity stood at around 90 GWe at the end of 2024, highlighting the importance of nuclear power in meeting Iran's energy needs.
The development of Iran's nuclear industry dates back to the establishment of a civil nuclear program in 1957 under the US Atoms for Peace program. Over the years, the country has set ambitious targets for nuclear power capacity, aiming to reduce its reliance on oil and gas for electricity generation.
While the path ahead for Iran's nuclear power industry remains uncertain, the country's nuclear capabilities and intentions will continue to be closely monitored by the international community. As tensions persist and security concerns mount, the future of Iran's nuclear program hangs in the balance, with far-reaching implications for regional stability and global security.
