(JI QUESTION 430.81 (SECTION 9.5.4)
In Section 9.5.4.2.1 of the FSAR you state that "The interior and exterior surfaces of the [ fuel oil storage] tank are corrosion i
i protected by carboline carbo zine 11 coatings.
I&E circular 77-15 discusses the incompatibility between diesel fuel oil and zinc.
The reaction results in a substance resembling soap which when heated becomes insoluble and this. substance could I
render diesel generators inoperable due to blocked fuel lines, injectors, etc.
This is not acceptable.
It is our position that fuel oil storage tanks be provided with, internal corrosion protection.
Therefore provide the results of tests which show that over the lifetime of the plant that the carboline carbo zine 11 coating used is compatible with the type of diesel fuel oil that will be used at your plant and that the condition described in the circular will not occur or replace the internal coating with a non-zine base type that is compatible with diesel fuel oil.
(SRP 9.5.4, Part II)
RESPONSE
1 Hope Creek will remove the existing inorganic zine coating from the diesel generator fuel oil tanks.
The tanks will be blasted to the white =etal criteria of SSPC-SPS.
Two coats of A=ercoat 1
No. 90 or ecuivalent will be applied to the tank interior, 9
