The following tests were conUcted for the Startup at Calvert Cliffs Unit One Cycle Seven. All tests were conducted in a manner similar to Initial Startup (Reference 1).

The results of these tests and comparison with predictions are as follows:
A. The proper functioning of the CEDMs and CEA position indication was verified through insertion and withdrawal of CEAs. All CEAs reached a 90% insertion in less than 3.1 seconds at hot, full flow conditions. The slowest CEA (54) reached 90% insertion in 2.91 seconds.

B. Reactor Coolant Flow was verified to be consistent with previous testing.
B. Reactor Coolant Flow was verified to be consistent with previous testing.
C. Initial criticality was achieved at 1436 ppm Boron with CEA Group 5 at 70" withdrawn. Predicted value was 1422 ppm Poron.
C. Initial criticality was achieved at 1436 ppm Boron with CEA Group 5 at 70" withdrawn. Predicted value was 1422 ppm Poron.
D. The CEA Symmetry Check verified that all CEAs were attached to their extension shafts. An evaluation of the quantitative reactivity change for dual CEAs yielded an azimuthal tilt estimate of about 14% which was greater than the 10% acceptance limit.       Investigation with various excore detector combinations confirmed that the assymetric excore
D. The CEA Symmetry Check verified that all CEAs were attached to their extension shafts. An evaluation of the quantitative reactivity change for dual CEAs yielded an azimuthal tilt estimate of about 14% which was greater than the 10% acceptance limit.
Investigation with various excore detector combinations confirmed that the assymetric excore


detector configuration used for this measurement was the cause of the apparent tilt. When a symmetric detector configuration was used, the tilt for a subgroup of peripheral CEAs decreased from about 14% to about 5%. For confirmation, the tilt was remeasured at about 18% power with the incore detector system and found to be about 3%.

SUMMARY

OF STARTUP TESTING FOR CALVERT CLIFFS UNIT ONE CYCLE SEVEN I.

The following tests were conUcted for the Startup at Calvert Cliffs Unit One Cycle Seven. All tests were conducted in a manner similar to Initial Startup (Reference 1).

A. CEDM/CEA Performance Test B. RCS Flow Verification C. Initial Criticality D. CEA Symmetry Check E. Critical Boron Concentration Measurements F. IsothermalTemperature and Power Coefficient Measurements G. Group Rod Worth Measurements II. Power Distribution Measurements II.

The results of these tests and comparison with predictions are as follows:

A. The proper functioning of the CEDMs and CEA position indication was verified through insertion and withdrawal of CEAs. All CEAs reached a 90% insertion in less than 3.1 seconds at hot, full flow conditions. The slowest CEA (54) reached 90% insertion in 2.91 seconds.

B. Reactor Coolant Flow was verified to be consistent with previous testing.

C. Initial criticality was achieved at 1436 ppm Boron with CEA Group 5 at 70" withdrawn. Predicted value was 1422 ppm Poron.

D. The CEA Symmetry Check verified that all CEAs were attached to their extension shafts. An evaluation of the quantitative reactivity change for dual CEAs yielded an azimuthal tilt estimate of about 14% which was greater than the 10% acceptance limit.

Investigation with various excore detector combinations confirmed that the assymetric excore

detector configuration used for this measurement was the cause of the apparent tilt. When a symmetric detector configuration was used, the tilt for a subgroup of peripheral CEAs decreased from about 14% to about 5%. For confirmation, the tilt was remeasured at about 18% power with the incore detector system and found to be about 3%.

E. Critical Boron Measurements - Table 1.

F. Isothermal Temperature and Power Coefficients - Table 2.

G. CEA Group Worth Measurements -Table 3.

II. Power Distribution Measurements - Table 4, Figure 1 and 2.

III.

All tests were within acceptance limits.
