99Mo IAEA Projects

The IAEA can assist Member States in their 99Mo work through various types of activities. These include:

  • Coordinated Research Projects
  • Technical Cooperation Projects
  • Regular program activities
  • Networks and coalitions
  • Participation in complimentary, international activities
  • Meetings
  • Missions
  • Publications
  • General Conference side-events

IAEA

Conversion of Major 99Mo Producers to LEU

  • Supported by US DOE-NNSA and the Government of Norway
  • Series of working group meetings for key stakeholders to

review progress, exchange information and explore

  • pportunities for mutually beneficial collaboration
  • Receiving updates on LEU

high-density targets, and accompanying chemical processes

  • Most recent meeting took

place 27-28 January 2014

IAEA

  • Draft publication on Feasibility of Small-Scale 99Mo

Production using LEU Fission or Neutron Activation Methods

  • In final review now;

scheduled for publication in 2014

  • Incorporates the results
  • f the Coordinated

Research Project on small-scale production (2005-2011)

Small-scale, non-HEU 99Mo production

IAEA

Small-scale, non-HEU 99Mo production

  • Technical Cooperation Project started in 2013
  • Aimed at assisting small-scale, national-level producers in

setting up their production capability;

  • NOT aimed at creating commercial producers
  • Will rely on LEU fission or n,gamma-based production
  • Open to any IAEA Member States wishing to receive

advice and assistance

  • Production infrastructure fact-finding missions were

completed to Mexico, Morocco, Peru, Poland, and

  • Romania. Similar missions were conducted in Egypt

(2010) and Malaysia (2011)

IAEA

  • Expert Missions
  • 99Mo production project progress review missions
  • Production infrastructure readiness missions
  • IAEA and project counterpart missions to 99Mo production

facilities and laboratories

  • EURASIA Coalition work
  • Reactors in Eastern Europe and former Soviet states

cooperating to produce low specific activity 99Mo via neutron capture of 98Mo (launched in 2008)

Small-scale, non-HEU 99Mo production

Full Cost Recovery & Managing

99Mo Waste Streams

  • Intended to study technical and economic

aspects of 99Mo waste streams in cooperation with the OECD-NEA

  • Work on this study was halted due to the low

response rate (<50%)

  • Without this information, the study would not

have the necessary data to contribute any meaningful analysis

IAEA

  • Target preparation (withstand heat

generated by the beam)

  • Radionuclidic separation Mo/99mTc: fast and

high yield

  • Recovery of the target: enriched and high

cost

  • Radionuclidic impurity: choose optimum

beam energy, time of irradiation and decay time; select the target carefully!

  • Delivery of 99mTc
