3.3.5 As a guide, during spray application, apply material as a heavy, i
wet coat, in even, parallel passes overlapping each pass by 50':
3.3.6 Apply NUTEC #10 at a spree ding rate of approximately 350-400 I
sq. ft./ gal.
Avoid excessive build up which will cause a i
" glazing" affeet after drying.
l 3.3.7 NUTEC #LO has a pot life of approximately I hour (at 75'F).
l No material shall be applied which has exceeded its pot life.
If this has occured, there is an increase in the viscosity of the material, a noticeable heat of exotherm and applied material j
will " crawl" and refuse to penetrate the concrete. All material j
thus applied shall be removed from the concrete with solvent and j
a clean cloth. All equipment shall be cleaned immediately and any l
remaining NUTEC #10 (expired) shall be discarded. Caution:
I Storage of NUTEC #l0 containers at high temperatures or in direct sunlight will greatly reduce its pot life.
NOTE:
Po t life stated above for unthinned coating is the recommended time and should be used as a guideline for coating usage time, however, ac tua! po t life may be longe r.
For unthinned coating or coating thinned less than 50*.,
the actual pot life is
{
determined by applicability af the cna t ing.
3.3.8 During application all arean found to contain sags, surface irregularities, or excessive buildup of NUTEC #10 shall be removed with solvent and a clean cloth and fresh NUTEC #10 I
applied.

Provide the basis for area figure in item 30 of CEL.
r
Response
a)
A takeoff was made from design drawings to determine number of Richmond Inserts inside the containment building. The area on the exempt log represents the total area of all Richmond inserts.
7 TXX-4249 August 10, 1984 QUESTIONS RELATIVE TO ALLEGATION NO. 6 a)
How much area is involved? Provide the basis for the area. Identify the NCR/DCA that places this item in the CEL.
Response

TIK-4249 August 10, 1984 QUESTIONS RELATIVE TO ALLEGATION NO. 7 a)
What is your method for incorporating updated manufacturer's recommendations into CPSES procedures?
b)
When were the recommendations in Imperial's January 16, 1983 letter incorporated into CPSES procedures?
Response
a)
Information received from coatings manufacturers are incorporated into application procedures by issuance of a Document Change Notice or formal revision to the procedure.
b)
The only recommendation made on January 19, 1983, was to pay particular attention to application parameters outlined in the letter. CCP-40 was already in accordance with these application parameters.
