Subject:
Station Battery Capacity to Satisfy Load Profile
Dear Mr. Johnson:
Letter P-85077 (dated 3/11/85), Attachment B-Battery Sizing, states a minimum battery capacity of 1080 amp / hrs would be required to satisfy the FSV emergency DC load profile.
The Exide computer modeling of our load profile requirements shows this number to be 1058 amp / hrs.
The Exide program specifies an FTC-15',1180 amp /hr battery as sufficient to satisfy our needs, with an 11.5% margin.
This calculates to a requirement of the above-stated 1058 amp / hrs.
This correspondence is to amend the 1080 amp /hr reference in letter P-85077 to 1058 amp / hrs of required battery capacity.
Vary truly yours,
$ Y W&
Don W. Warembourg Manager, Nuclear Engineering Division DWW/MR/dh
