Summary
When final system acceptance tests were performed on Project CGI-844, 100-K Coolant Backup System, it became evident that less than the design flow of 32,000 gpm was being achieved. Since the tests indicated that only 28,200 gpm was being supplied to KW and 26,700 gpm was being supplied to KE, it was obvious that the cross-tie lines had higher friction losses than anticipated. A study was therefore made to determine the effects of crosstie line cleaning to remove corrosion nodules. Calculations showed that with the lines cleaned, flows of 31,800 gpm to KW and 30,800 gpm to KE would result. The lines were subsequently cleaned, and on February 16, 1963, flow tests were conducted. The resultant flaws were 31,500 to KW and 30,900 to KE. On November 1, 1963, flaw tests were again conducted to determine if corrosion buildup in the cross-tie line was affecting the flow capacity of the system. While the flow data has not been issued by the test engineers, initial indications are that the present capacity of the system is approximately 29,500 gpm to KE and 30,000 gpm to KW, or a loss of approximately 1500 gpm on each side. The purpose of this document is to review the actual flow requirements of the coolant backup system for the various reactor operating conditions to determine when decisive steps should be taken to increase the capacity of the system to prevent any reduction of operating levels, and to point out the possible solutions being considered if a capacity increase is required.
