will be used for large-volume utilization
at Unit 4. The companies' project schedule
suggests first receipt of ammonia
for the Unit 4 project will be in 2023. If
the large-volume tests are successful,
the project may be expanded. Japan's
national research agency New Energy
and Industrial Technology Development
Organization (NEDO) is backing a project
to showcase a 50% ammonia cofiring
rate at Unit 4 or 5 at the Hekinan
plant by 2028. JERA is ultimately looking
to shift its massive coal-fired fleet to
100% ammonia by 2050.
Shin-Hanul Unit 1, an APR-1400 Nuclear
Reactor, Achieves Criticality. Shin
Hanul Unit 1, the first of two 1,350-MWe
APR-1400 reactors that are under construction
in Uljin county, North Gyeongsang
province, South Korea, attained
a sustained chain reaction for the first
time on May 22, the plant's owner Korea
Hydro and Nuclear Power (KHNP) said.
KHNP plans to produce power at the
plant for the first time early in July after
Shin-Hanul Unit 1 undergoes a performance
test of the power plant system.
Safety remains a top priority, KHNP said.
Shin-Hanul Unit 1 is Korea's 27th nuclear
power plant. After obtaining an operating
license from the Nuclear Safety and Security
Commission on July 9, 2021, the
reactor was loaded with fuel, followed
by hot functional tests to activate the
reactor. South Korea has two APR-1400
units: Shin Kori 3 and 4, which began
commercial operation in December 2016
and September 2019, respectively. Construction
of two other APR-1400s-Shin
Kori Units 5 and 6-began in April 2017
and September 2018. They are slated to
be completed in March 2023 and June
2024. The APR-1400 is an evolutionary
pressurized water reactor with its origins
in the CE System 80+ model.
800-MW Kusile Coal-Fired Unit in
South Africa Begins Commercial Operation.
The 800-MW Unit 4 of Eskom's
coal-fired Kusile Power Station Project
in South Africa's Mpumalanga region
on June 1 began commercial operation,
marking the end of a five-month " vigorous "
testing and optimization program.
Unit 4 is the fourth unit completed at the
six-unit 4.8-GW plant. Construction and
commissioning activities on the remaining
Kusile Units 5 and 6 continue to progress
" according to plan, " Eskom said. Kusile is
South Africa's largest construction project
and will be the world's fourth largest coal
plant at completion. The plant will also be
South Africa and Africa's first to use wet
flue gas desulfurization (WFGD), a techJuly

nology used to remove sulfur oxides from
coal plant emissions. Eskom, which has
grappled with repeated load-shedding
events, hailed the unit's commercial operation.
" The Kusile project team and Eskom
are working tirelessly to complete
the rest of the project without any further
delays as the country needs every megawatt
of power it can get, " said Bheki Nxumalo,
the Eskom Group Executive for
Capital Projects.
EXERGY Cultivates Partnership for
Geothermal Power Development in
Japan. EXERGY, an Italian developer of
Organic Rankine Cycle (ORC) systems,
is teaming up with GPSS Group, a subsidiary
of Japanese geothermal project
developer Geothermal Development
& Investment Inc. (GDI), for the exclusive
distribution of turnkey geothermal
power plants in Japan using EXERGY's
ORC technology. EXERGY, which has
designed 450 MW of geothermal power
capacity worldwide, on June 6 said
its partnership with GDI would " give
birth to the development of joint MW
scale projects and contribute to the
growth of geothermal development in
Japan. " Japan, it noted, has the world's
third-largest geothermal resource potential.
" Knowing that the Asian region
has a huge renewables potential
to tackle, we have been pursuing this
key commercial area for years. We consider
Japan in particular as a promising
market for geothermal development, "
said Marco Frassinetti, sales director of
EXERGY International.
China Starts Up 100-MW Solar-Tidal
Hybrid Plant. Longyuan Power, a partially
owned subsidiary of state-owned China
Energy Investment inaugurated China's
first solar-tidal hybrid plant in Wenling
City of east China's Zhejiang Province
on May 30. The project links 185,000
photovoltaic modules installed on raised
stakes over 133 hectares of a tidal pool,
essentially linking 100 MW of floating
solar PV power production with the 4.1MW
Jiangxia Tidal Power Plant. Jiangxia
Tidal Power Plant, which was completed
in 1986, is the fourth-largest tidal station
in the world after the Sihwa Lake Tidal
Power Plant in South Korea, La Rance
in France, and Annapolis in Canada. The
Wenling project seeks to harness energy
from the sun and tidal energy, which relies
on the moon's gravity, the company
noted. The plant is reportedly outfitted
with digital technologies that allow data
analysis and rapid remote diagnosis. ■
