The measured worth was derived from the calculated value of ln k1/k2, where k1 and k2 were calculated with the measured buckling before and after insertion of the control rods, which replace fuel rods in arrays at the center of the experiment. The standard deviation in the measured worth is about 0.3%
based on the uncertainties in the measured axial buckling.

- 3. Steam pressure Transducer and process computer readout steam enthalpy
- 4. Reactor coolant Thot Narrow range RTD and data acquisition system or DVM readout RCS hot leg enthalpy
- 5. Reactor coolant Tcold Narrow range RTD and data acquisition system or DVM readout RCS cold leg enthalpy RCS specific volume
- 6. Reactor coolant pressure Transducer and process computer readout RCS enthalpy and specific volume Other information required for the calculation is as follows:
- 7. Feedwater venturi coefficient from vendor calibration.
- 8. Primary system heat losses and pump heat input obtained from calculations.
Notes:
- 1. In addition to the originally-installed venturi flow nozzle instruments, ultrasonic flow meters were later installed on Unit 1 to provide more precise feedwater measurement. These ultrasonic flowmeters measure both feedwater flow and temperature, and provide input to the core power calorimetric calculation.
