Dear Mr. Keppler:
Pullman Sheet Metal Works, Inc. , a supplier of miscellaneous IIVAC items for the Marble 11111 Nuclear Generating Station has determined that we have misinterpreted an American Welding Society Welding Symbol. Due to our misinterpretation of a " Weld All Around" symbol there are occassions where we have omitted required welds.
Pullman Sheet Metal Works, Inc. is also currently supplying IIVAC items at Braidwood Nuclear Power Station (Braidwood, IL), Plant Alvin W. Vogtle Nuclear Power Station (Waynesboro, GA), and St. Lucie Plant Unit #2 (South Pr. t St. Lucie, FL) .
Aftec evaluating these jobs, we have determined that this problem does exist at the Braidwood job, however, it does not exist at St. Lucie or Vogtle.
If you have any questions, please feel free to contact me 0312-374-6700 Ext. #236.
Sincerely, PULIJIAN SilF T ETAL WORKS, INC.
