Q 9: Are the proposed activities included in TRIUMF’s 5-year plan appropriate
and consistent with the needs and ambitions of the physics community, both in
Canada and internationally? Will the plan elevate Canada’s reputation and
international leadership in nuclear medicine, nuclear physics, materials
science, particle physics and accelerators research?
Q 10: Do the requested resources and the laboratory’s capabilities give
reasonable confidence that the activities of the 5-year plan can be carried out
to achieve the stated outcomes?

Budget Scenarios
Scenario A – Exploit opportunities for enhanced impact
• Tc-99m: Prepare Canada for Chalk River reactor shutdown (2016)
• IAMI:
• Pursue R&D that defines the current state-of-the-art in acceleratorbased isotope production
• Foster Canadian excellence by bringing together researchers with
related interests and needs
• Provide expertise and facilities to enable their research
• Nurture research translation
• PPRC: Formal PERs regulatory program comes online
Scenario B – Maintain core, avoid growth & increase risk
• Retract to focus on existing, focused program. Hold status quo
• Emphasis will be on existing program: PPRC, CCM
• Reduced IAMI scope
13 Nov 2013
Nuclear Medicine
34
Scenario C - Downward spiral
Scenario C – Reduced resources, restrict program
• Nuclear Medicine at TRIUMF becomes irrelevant
• Concentrate research on core Operations (TR13, PPRC)
• Increased risk to PPRC Parkinson’s program (regulatory)
• Increased chance of major failure(s) leading to extended
downtime
• Reduce support for staff and operating activities with targeted,
deep cuts
• Reduced competitiveness: Research and Commercial
• Increased scientific backlog
• Loss of HQP (recall seconded FTEs: NRCan effort), Users
• Canada would lose a unique resource and skillset to advance an
accelerator-based (non-reactor) isotope production paradigm 35

Summary
• TRIUMF Nuclear Medicine has capitalized on its core
competencies to:
• Lead and innovate with new partnerships: 99mTc
• Evolve program to explore new initiatives: BCCA
• Continue to enable our long-standing partners: PPRC
• With requested funding (Scenario A):
• TRIUMF will establish the IAMI as a regional enabler with
national and international reach
• Allow for increased focus on emerging regulatory
requirements for PERs
• Provide a means to create social
and economic growth through
innovation and commercialization
