Campus Thermal Integration

Residual heat from Aegis can serve campus thermal loads, using energy that a plant would otherwise reject.

Putting residual heat to work

Direct energy conversion turns most of the burner's output straight to electricity, but a residual heat load remains — neutron heating from the 5.44% neutron fraction plus system losses. Rather than reject all of it, an installation can route useful-grade heat to campus thermal loads such as space heating or process heat, using energy that would otherwise be lost.

How integration works

A heat-recovery loop taps the plant's cooling system at a useful temperature and delivers it to campus loads through a thermal distribution network. Because heat does not travel far efficiently, this favours co-location of thermal loads with the power block. The recovered heat is a bonus on top of the electrical output, not a substitute for heat rejection, which must still handle the full duty when thermal demand is low.

• Recover useful-grade residual heat from cooling
• Serve campus space heating or process heat
• Favours co-located thermal loads (heat travels poorly)
• Full heat rejection retained for low-demand periods

A resilience angle

Thermal integration also adds resilience: an installation whose heat comes from the same sovereign source as its electricity is less dependent on separate fuel-fired boilers, extending the fuel-independence benefit to the thermal side of the campus.

Design-stage and site-specific, thermal integration is framed physically as recovering useful-grade residual heat that a plant would otherwise reject, with full heat-rejection capacity retained for the periods when campus thermal demand is low. Because the recovered heat and the electricity come from the same sovereign source, an installation that adopts thermal integration also shrinks its dependence on separately-fuelled boilers, widening the fuel-independence benefit across the campus.
