Dear Sir:
Three Mile Island Nuclear Station, Unit II (TMI-2)
Operating License No. DPR-73 Docket No. 50-320 Reactor Containment Building Atmosphere Cleanup In our letter of March 31,1980 (TLL 145), Metropolitan Edison forwarded th'e results of the Reactor Building air samples analyzed for Strontium 89/90.
The analytical results reported in that letter were incorrect. The incorrect results were due to a reporting error by the analysis subcontractor. Although the exact concentration values for each isotope changed, the magnitude of the total Strontium concentration in the reactor building is not significantly different. The corrected values for the Strontium 89/90 analyses are attached.
Sincerely,
- b. K. Hovey Director, TMI-II GKH:MM:SDC: hah Attachment cc:
