REFERENCE:

CP CO LETTER SERIAL 9858 DATED CCTOBER 1,1981 This letter is to modify our previous response, Serial 9858 dated October 1,1981, which closed out the subject bulletin. The modification is that the table shovn in our previous respenss' indicates that the reactor coolant pu=p seal drain tanks,1T35/2T85, are equipped with vacuus breakers and a nitrogen cover gas system.

A recent design change vill remove the reactor coolant pump seal drain tanks frem the Midland design.

Revision 3h of the FSAR, to be submitted in June 1981, vill revise thq appropriate FSAR sections and tables to eliminate reference to these ta:de s.
