Sl]EMARY OF STARTUPTESTING FOR CALVERTCLIFFS UNITTWO CYCLE EIGIIT i
1.
The following test were conducted for the statup of Calvert Cliffs Unit Two Cv-cle Eight. The only difference from previous startup testing is that the mea-surements at the 50% power plateau have been replaced with power distribution measurements at 30%, 60%, and 85% power. This modified testing program is de-scribed in the Unit 2 Cycle 8 Reload License Submittal (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 G.
Group Rod Worth Measurements 11.
Power Distribution Mesaurements 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 veri-fied through insertion and withdrawal of CEAs. All CEAs reached a 90% in-sertion in less than 3.1 seconds at hot, full flow conditions. The slow-est CEA (35) reached 90% insertion in 2.53 seconds.
B.
Reactor Coolant Flow vas verified to be consistent witn previous testing.
C.
Initial criticality was achieved as describe 3 in the Calvert Cliffs FSAR by boron dilution on July 1,1987, with all CEAs withdrawn except the lead CEA grour at mid-core.
D.
The CEA Symmetry Check verified that all CEAs were attached to their ex-tension shafts. An evaluation of the quantitative reactivity change for dual CEAs yielded a core avera2+ tilt estimate of 8.8%, within the 10% ac-ceptance limit.
