At the by: various test plateaus RCS components were observed for even expansion a.) visual observation b.) go no-go measurements c.) measurements at predetermined locations These measurements were compared to the original cold ambient measure-ments and also against each other to assure that no component was locked up.

C. TEST EVENTS:

Prerequisite sign offs were started April 11, 1983 and were completed on 05-09-83. .

Initial ambient measurements were started on 05-09-83 and final ambient measurements were completed 07-13-83.

Throughout the heatup and cooldown to major problems were observed. There was minor interference with insulation being deformed at the Steam Generator key areas and at the top of the Pressurizer, and some of the small piping coming off the RCPs was' restricted from moving. Additional problems were bolts on pressurizer key shims. interference of RCP 2A motor cooler with a the above problems: The following SFRs were written to document SFR #

,( D. TEST EVENTS (cont'd): ,

.Due'to the unscheduled cooldowns and subsequent heatups it was found acceptable to delete the 460 and 260 F cooldown plateaus. TCN 08 reflects this change in the procedure. During the above mentioned cooldowns and heatups the RCS was closely monitored visualIy and by actual' measurements.

'Ihese measurements are documented as part of. the test Icg. The procedure performed-very well in achieving its. goals and mostly only minor changes were required.; A total of 8 TCNs were required and are listed below.

TCN # Scope /Non Scope Description 01 scope change snubber acceptance criteria 02 scope add additional appendices 03 non scope delete note with regard to 24 hr. time period prior to start of test 04 non scope interchange of available control room instrumentation 05 non scope add additional measuring tools 06 scope add Reactor Coolant Pumps "V" dimensions to correct saveral tgpos 07 non scope 08 scope delete 460 F and 260 F cooldown plateaus.

E. TEST RESULTS:

Obtained measurements fell well within the required acceptance criteria with the exception of dimension 'LL' of the #2 pressurizer key at the 565 F plateaus which has been documented by TERs 01 and 02 and SFR-1RC-115.* The system responded well and repeatability thru the various heatup / cooldown cycles was excellent. One of the installed capacitance probes failed at the

final ambient plateau (TER03). This was only for supplemental data and had no

'effect on the test results.

F. CONCLUSION:

'As installed the RCS expanded as was expected with no binding or sticking of the major components. Movements were as expected and after cooldown all components returned.to their starting position within a 1/16". The system as installed will perform as designed. 1 C. REComCNDATIONS:

Based on the results of the test, no retesting of the system is required with the exception of areas where additional shims will be installed and which will be tested in accordance with Post-Core Hot Functional procedure 73HF-1RC07. The procedure as written and the methods employed to obtain the measurements were more than adequate and no changes are recommended. Based on the above approval of the test results is recommended.

• Retest will be conducted during Post-Core Hot Functional Testing.
