MSRE Dynamics

– How well can MSRE dynamics be predicted over its full power range?

  • Inherent safety, stability, controlability
  • Low-power oscillations were predicted
  • Opportunity: Case made for a detailed study –

theory & experiment

  • RESULTS:
  • Dynamics are well-understood – full range of

powers

  • Inherent safety features confirmed

As power increases, oscillations are more damped, & at higher frequencies

Theory: Ball & Kerlin – ORNL-TM-1070 (Dec. 1965) Experiment: Kerlin, Ball et al – Nuclear Technology 10 (Feb. 1971)

MSRE dynamics tests – PRBS rod control

  • Dark & stormy night…
  • PRBS test running smoothly
  • Rod “jogger” sticks in “withdrawn” position
  • Power level rises, exceeds “maximum”*
  • Power decreases (to normal) on its own
  • Experimenters (Tom Kerlin & Syd) record event, go home

PRBS test excitement…

(* highest ever!…)
