Nuclear energy technology elevated worldwide in 2017 for the fifth successive yr in keeping with a report launched by the World Nuclear Association (WNA). Production from nuclear vegetation reached 2,506 TWh in 2017, greater than 10% of world electrical energy demand.
The common capability issue for the world’s nuclear energy vegetation elevated year-over-year to 81.1%, persevering with the high-performance displayed during the last 20 years, throughout which common capability components have persistently hovered round 80%. In an August 15 press launch asserting the publication of “World Nuclear Performance Report 2018,” the WNA famous that reactor efficiency has been “maintained no matter how lengthy a reactor has been in operation.” It mentioned there was no proof of “age-related decline.”
There have been 59 reactors below building on the finish of 2017. Four reactors have been related to the grid throughout the yr, with a median building time of 58 months. Four initiatives have been began throughout the yr and two have been halted, together with two models on the V.C. Summer enlargement undertaking within the U.S.
Of the 448 reactors that have been operable on the finish of 2017, greater than half have been within the U.S. and Europe. However, reactor retirements proceed to outpace capability additions in each of these areas. New international locations, although, are coming into the nuclear energy membership. In Bangladesh, Prime Minister Sheikh Hasina inaugurated the primary building work of the nuclear plant at Rooppur on November 30, 2017. Turkey additionally formally started building on its first nuclear unit on the Akkuyu website in December 2017, though precise building on the reactor didn’t begin till April 2018.
China continues to dominate the new-build market, accounting for 3 of the 4 grid connections in 2017, and 18 of the 59 reactors below building in the beginning of 2018. The nation can be main the way in which on two first-of-a-kind reactor initiatives—the AP1000 and EPR designs. Sanmen 1, an AP1000 unit, and Taishan 1, an EPR unit, each achieved first criticality in June 2018.
Nonetheless, the WNA mentioned construct charges must enhance considerably to attain its Harmony program goal of 1,000 GW of recent nuclear capability by 2050. Harmony is a world imaginative and prescient for the way forward for electrical energy. The WNA says to satisfy the rising demand for dependable, reasonably priced, and clear electrical energy, the world wants all low-carbon power sources included as a part of a various energy combine. It envisions nuclear power capability increasing to provide 25% of electrical energy by 2050, which led to its 1,000 GW new-nuclear-capacity aim (Figure 1).

“There is not any sustainable power future with out nuclear power. We will want all low-carbon power sources to work collectively. Nuclear capability should increase to attain the business’s Harmony aim to allow nuclear power to provide 25% of the world’s electrical energy demand by 2050,” Agneta Rising, director normal of the WNA, mentioned within the August 15 press launch.
