1、Basic information of the Plant
Radioactive waste treatment options
For radioactive gaseous waste
First remove NOx ,aerosol, C, and I etc.,
and then release into atmosphere
1、Basic information of the Plant
For radioactive liquid waste
HLLW
Process ILLW
Non-process ILLW and LLLW
Spent solvent
1、Basic information of the Plant
For radioactive solid waste
Being classified and treated.
Conditioned IL-LL solid wastes go to IL-LL waste
disposal site.
Conditioned α and HL solid wastes will be
temporarily stored pending final deep geological
disposal.
1、Basic information of the Plant
Construction planning:
Receiving spent fuel in 2018
Start up reprocessing in 2025
2、Progress of the Project
Siting:
Performed both in the coast and inland area.
The preliminary survey work of the inland
site has been performed.
2、Progress of the Project
Preliminary feasibility study and the
project proposal :
The preliminary feasibility study works such as
technical options, investment estimation and
economic analysis etc. have been performed.
The preliminary feasibility study report and the
project proposal have been submitted to
government for approval.
2、Progress of the Project
Cooperation with foreign countries:
CNNC has contacted and discussed on the
potential cooperation with relevant organizations
and enterprises of Russia, France and UK.
China welcome the countries or enterprises which
have reprocessing ability to cooperate with China,
if the conditions are permissible.
3、Site characteristics
 The site is located in Gansu province.
 The topography of the site is flat, and the slope
of natural topography is about 1%.
 The population density is very low within 20km.
 There are no industrial, agricultural and health
facilities within 15 km of the site.
4、R&D of reprocessing
Ability :
Had constructed the reprocessing plant for the
production reactor spent fuel.
Has gain preliminary success for the hot test of the pilot
plant for power reactor spent fuel.
Has mastered the design and construct tech.
R&D :
Approved the R&D of reprocessing to further research
key reprocessing technology, wishing to enable China’s
reprocessing technology reach the world’s advanced level
nowadays.
5、Product outlet
Main outlet of the Products is to recycle them in
thermal or fast reactors after being manufactured
into UO2 or MOX fuel.
Chinese government is undergoing the study for the
problem of the outlet of the Pu product, one of the
options is to recycle them into fast reactors directly.
6、Concluding remarks
China has decided to construct a large-scale spent fuel
reprocessing plant, which is an important activity on the
management of spent fuel in China.
China has preliminarily mastered the design and construction
technology of spent fuel reprocessing plant. China has
confidence that the large plant can be successfully constructed.
In order to speed up the construction, China welcome the
countries or the enterprises which have reprocessing ability to
cooperate with China, if the conditions are permissible.
THANK YOU !
