Units 5 and 6 at Tianwan - Tianwan Phase III - both feature ACPR1000 reactors. First safety-related concrete was poured for unit 5 on 27 December 2015, with that for unit 6 poured on 7 September 2016. Tianwan 5 entered commercial operation in September last year and unit 6 is scheduled to enter commercial operation by the end of this year.

Grid-connection of unit 6 potentially heralds the start of construction this month of unit 7. On 29 April, Ma Mingze, director and general manager of China Nuclear Power, said that the schedule in its contract with Russia's Rosatom anticipates construction of units 7 and 8 in May this year.

The Tianwan plant is owned and operated by Jiangsu Nuclear Power Corporation, a joint venture between CNNC (50%), China Power Investment Corporation (30%) and Jiangsu Guoxin Group (20%).
