Subject:
Design Details of NUREG-0737, Item II.F.1.6, Containment Atmospheric Monitor
Dear Sir:
By letter dated June 9,1983, we submitted a detailed design description of the containment atmosphere monitor to be installed at the Pilgrim Nuclear Power Station.
It has come to our attention that the design gas concentration of the two compressed gas bottles in the calibration gas subsystem has been modified from 4% H2 and 7% 02 to 19.9% H2 and 20.9% 0. This alters information provided 2
on Page 8 of the attachment to the design description letter.
Very truly yours, l
