Construction of Zhangzhou-3 began in February 2024 and of Zhangzhou-4 in September 2024.
At a nuclear power reactor, the inner containment acts as a hermetic protection system, designed to withstand high external and internal pressures and protect against radiation release. It consists of several steel rings and a steel dome welded together.
CNNC said a single steel liner ring has a diameter of 46.8 metres and weight of about 140 tonnes.

Cold hydraulic testing verifies that welds, joints, pipes and components in the primary circuit are able to withstand pressures higher than those during normal operation.
In October 2024, workers completed assembling the reactor at Rooppur-1, including the reactor internals and head, and have loaded dummy fuel assemblies in the reactor core.
Initial concrete pouring for Rooppur-1 took place in November 2017, followed by Rooppur-2 in July 2018.

Work began in 1987 on two additional VVER-440 reactors at the Mochovce site near Nitra in southwest Slovakia – Mochovce-3 and -4. However, in progress was halted in 1991 due to a lack of funds and did not resume until November 2008.
Mochovce-3 reached first criticality in October 2022 and completed commissioning a year later.
For Mochovce-4, Slovenské Elektrárne has said that 90% of all systems had been turned over to commissioning in 2023.

“This is a key step in building our capabilities to supply advanced nuclear fuels,” said Tarik Choho, president of nuclear fuel at Westinghouse.
Westinghouse has said that the compact design of the eVinci microreactor, with a capacity of up to 5 MWe, enables easy transportation and fast onsite deployment. The reactor operates with minimal moving parts, functioning much like a nuclear battery.

The first tier for El Dabaa-2 was installed in October 2024 at the site, about 300 km northwest of the Egyptian capital Cairo on the country’s Mediterranean coast.
Rosatom said that after installation of the second tier, the reactor building became the tallest structure onsite, reaching slightly above 20 metres.
