Dear Mr. Page:
Enclosed are eight copies of Drawing D-5008-2023, which were omitted from our application dated June 19, 1981 for dry powder storage on conveyors and mezzanine storage of agglomerated press feed.
In addition, page 8-7 has been revised to show the correct drawing number.
Please advise if additional information is required.
Very truly yours, COMBUSTION ENGINEERING, INC.

8.1.5 Blending Blenders are 14 inches in diameter. The blending operation involves no hydrogeneous material except for the moisture contained in agglo-merated press feed recycled to the mill. The atmosphere is contin-uously monitored for humidity and an increase in moisture will cause an alarm and subsequent cessation of the blending operation. The Nuclear Safety Evaluation is provided in Section 9.0 Blenders are arranged on six foot centers forming an inline array and are located at least four feet from other SNM-bearing equipment.
- 8.1.6 Packaging and Storage Dry UO2 product is transferred into stainless steel cans (9.75" t X 11" long) in the powder packaging hoods. A maximum of 30 Kg U02 per can is allowed. A 4 mil poly bag may be used as an inner liner.
If used, it is sealed at the top with tape. The can lid is a friction-fit type which is sealed on the eatside with tape. This precludes any in-leakage of moisture from atmospheric humidity (the powder is not hygroscopic anyway) or flooding. Thus, the UO2 pr duct is kept dry (typically <.05% moisture) and moderation control is assured under all conditions.
Section 9.3 des-cribes all moderation controls in detail.
The sealed cans of dry U02 product are then transferred to one of 5 roller conveyors on the north side of Building #255 as shown in Items 58, 59 and 60 of Drawing D-5008-2023, dated 2/5/81. The entire building is above the 100 year flood level as determined by the U. S. Army Corps of Engineers in their Special Study for Joachim Creek, dated March 1980.
Even if flooding were possible, the 30 Kg weight of the cans con-l taining high density U0 w uld prevent then from floating and being moved.
2 Building #255 is not sprinklered and firefighting would be by dry chemical means. Thus, criticality safety is assured through moderation control (1 4.1% enriched 00 cannot be made critical without moderation).
