P. L. Barnes letter to J. G. Keppler dated August 12, 1983
Dear Mr. Keppler:
Reference (a) requested that the Commonwealth Edison Company provide a written report regarding use of ASME Nuclear Code pumps and spare parts manufactured by the Hayward Tyler Pump Company.
Reference (b) provided the initial response for Byron Unit 1.
We committed to provide the results of the pump performance test and the system hydrostatic pressure test following their completion.
The attachment to this letter provides those test results.
To the best of my knowledge and belief, the statements contained in the Attachment are true and correct.
In some respects, these statements are not based on my personal knowledge but upon information furnished by other Commonwealth Edison employees, consultants and contractors.
Such information has been reviewed in accordance with Company practice and I believe it to be reliable.

ATTACHMENT BYRON STATION UNIT 1 Sapplemantal Response To IE Bulletin No. 83-05 "ASME Nuclear Code Pumps and Spare Parts Manufactured by the Hayward Tyler Pump Company" Item 1.c.:
Results of pump performance test on Hayward Tyler booster pump (lSXO4P) taken af ter the first 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> run:
Suction Pressure 68 psig Discharge Pressure 115 psig Essential Serv. Water Fluid Temperature 480F Flowrate 406 gpm Bearing Temperature 91cF Vibration Signatures Vibration acceptable Leakage on Mechanical Seal No leakage The pump developed a differential pressure of 47 psid pumping water at a temperature of 480F.
The developed head was calculated as follows:
(ll5-68)psig x 2.307 ft = 108 ft. H O 2
pHg at a flowrate of 406 gpm This compared to the operating point of 420 gpm at 100 ft, proved the capability of the pump to provide rated flow and pressure.
The bearing temperatures and vibration

signatures taken were acceptable. Overall, the Hayward Tyler Booster Pump performed as designed.
Item 1.d:
The system hydrostatic pressure test was performed and found to be acceptable.
