1. When reactor power is decreased, the process is reversed. 2. Under this control mode, the turbine will automatically follow reactor power changes. 3. In US nuclear submarine propulsion, full speed is 50 % reactor power . 4. At low reactor power , therefore, the inlet temperature may become dangerously high. 5. An onboard plasma reactor powers all of the T-X's systems. 6. It is produced from 16 O ( in water ) via an reactor power operation. 7. Both systems, however, have deficiencies, most noticeably at low reactor power levels. 8. The 135 Xe concentration peaks about 11.1 hours after reactor power is decreased. 9. Doppler broadening therefore creates a negative feedback because as fuel temperature increases, reactor power decreases. 10. The tank contains thermocouples for sensing the water temperature and ion chambers for monitoring the reactor power .
