Thailand Thailand is considering a

decision to launch a nuclear

power program. Currently,

Thailand is preparing the

infrastructure to support a

potential nuclear power

project in the future.

Human Resources Development

With no clear direction on the future of nuclear energy, not many

universities have established a specific program for nuclear sciences and

nuclear engineering. The most prominent existing program is in

Chulalongkorn University’s Nuclear Engineering Department. The program

offers nuclear engineering degrees at the graduate level and new

curriculum at the undergraduate level was introduced in June 2017.

Based on IAEA’s INIR of December 2010, Thailand is ready to make

a knowledgeable commitment to nuclear power. In the future, if the

Government makes the decision to opt for nuclear energy, the

following phases will take place. …..

In PDP2015, 2 000

MW of nuclear

power is planned,

accounting for 5%

of total installed

capacity by the end

of 2035.

The Evolution of Nuclear Power

Enhanced Safety (Resistance to sever damage with radioactivity release)

Attractive Economy (Simple, 60 years lifetime, reduction of capital cost

and construction time)

Harmonization with Environment (Safety, higher burn-up, waste minimization)

Gen III nuclear reactors are essentially Gen II reactors with

evolutionary, state-of-the-art design improvements.

These improvements include fuel technology, thermal efficiency,

modularized construction, safety systems (eg. passive systems),

and standardized design.

Improvements in Gen III reactor technology have aimed at a

longer operational life, typically 60, potentially to exceed 60

years, prior to reactor pressure vessel replacement.

Double containment

• Double-containment with large free volume,

which improves safety performance under

design basis condition (DBC) and severe

accidents conditions.

• Ventilation system in double-containment

annulus, which reduces the risk of

radioactive release to the environment in

case of accidents.

• Resistance to the impact of a large

airplane crash.
