SUMMARY

OF STARTUP TESTING FOR CALVERT CLIFFS UNIT TWO CYCLE FIVE I. The following tests were conducted for the Startup at Calvert Cliffs Unit Two for Cycle Five. 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. Isothermal Temperature and Power Coefficient Measurements i

G. Group Rod Worth Measurements II. Power Distribution Measurm'ents

\i .

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 (57) reached 90% N irsertion in 2.56 seconds. Due to a faulty reed switch stack on CEA 44, only the 100% insertion time was measured. A time of 2.58 seconds was measured for 100% inse-tion which is less than required for 90% insertion. -

e. .

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

C. Initial criticality was achieved at 1415 ppm Boron with CEA Group 5 at 70" withdrawn. Predicted value was 1373 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 less than 8% Acceptance limit is less than 10%

E. Critical Ikron Measurements - Table 1.

F. Isothermal Temperature and Power Coefficients -Table 2.

G. CEA Group Worth Measurements -Table 3.

11. Power Distribution Measurements -Table 4, Figure 1 and 2. I III. All tests were within acceptance limits.
