Problem Description & Market Need
(What is the problem? Or, What is needed in the market?
And, How big is the potential market? What is the disease
(if it’s a medical talk)? )
• Efficient reprocessing of wastes arising from nuclear
power remains one of the most complicated problems of
radiochemical
industry.
Long-lived
radionuclides,
especially actinides, are the most hazardous components of
the high level wastes (HLW) of nuclear power stations.
• Their separation from the total waste mass and disposal or
reprocessing (transmutation) should enable significantly to
raise the ecological safety and efficiency of nuclear fuel
cycle. A combined approach to HLW reprocessing, i.e. the
recovery of several radionuclide groups immediately in
one cycle, seems to be promising.

Brief technology description
•
The HLW partitioning problem can be solved
by the extraction technology with the use of
organophosphorus extractants recovering
TRU, technetium and platinides. The widely
used extractants like trialkylphosphine oxide,
carbamoylphosphine oxides or diphosphine
dioxides possess low efficiency and
insufficient selectivity, affording no
separation of hazardous radionuclides from
acidic high-level waste.

•
We propose a new class of perspective
extractants on the base of calixarenes
functionalized with phosphine oxide,
carbamoylphosphine oxide or diphosphine
dioxide groups. In such compounds the
binding groups may be best located around a
metal cation, increasing the extraction
efficiency and selectivity to a great extent.

Advantages
(What is my unique and overwhelming technology advantage?)
• Calix[4]arene alkylphosphine oxides,
carbamoylphosphine oxides or diphosphine
dioxides developed jointly by the Institute of
Organic Chemistry NASU (Kiev) and Khlopin
Radium Institute (St. Petersburg) extract
simultaneously actinides, lanthanides, technetium
and palladium from real HLW hundred times more
efficient than the industrial extractants. In three
contacts ~ 99,9 % of gross -activity, more than
98 % of Tc and Pd were recovered from real HLW.

Stage of development (clinical tests if medical) and
international patents
• The Institute of Organic Chemistry of the
National Academy of Sciences of Ukraine is
enable to product the calixarene extractants in
kilo scale quantities.
• The testing of the calixarene extractants has being
successfully performed with the real HLW on the
“MAYAK” plant by specialists of the Khlopin
Radium Institute, St.-Petersburg, in the
framework of the joint project STCU (RUS-09) /
ISTC (2068).

Targeted Market Segment
(Who needs it? How many will they need? What
price are they willing to pay, what do they pay now?)
• Any Atomic Power Station
• Radiochemical Enterprizes

Competition
(Who is my competition? How will I beat the competition?)
• TOPO-process (40% of heteroradical
phosphinoxide in dodecane
• TRUEX- process (0,2 М CMPO + 30 %
ТBP in dodecane)
