SUMMARY

OF STARTUP TESTING FOR CALVERT CLIFFS UNIT ONE CYCLE EIGHT I. The following tests were conducted for the startup of Calvert Cliffs Unit One Cycle Eight. All tests were conducted in a manner similar to Unit 1 Cycle 8 Reload License Submittal (Reference 1). Additional tests were performed and are described in Section III.

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

H. 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 (1) reached 90% insertion in 2.62 seconds.

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

C. Initial criticality was achieved at 1595 ppm Boron with CEA Group 5 at 45.7" withdrawn. Predicted value was 1624 ppm Boron.

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 7.70%, well within the 10%

acceptance limit.

E. Critical Boron Measurements - Table 1.

F. Isothermal Temperature and Power Coefficients - Table 2.

G. CEA Group Worth Measurements -Table 3.

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

III. All tests were within acceptance limits.

Electrical Generator insulation repairs provided the opportunity to perform additional aero-power measurements off critical path. Given this opportunity, the worth of the shutdown CEA banks were also measured and the critical boron concentration determined with all CEA's inserted except the most worthy CEA.

Table 5 provides the results of these measurements.
