Sect. ion 11.4 Seabrook j

1.

The overflow from the waste concentrates tank goes to a floor drain.

The possibility exists for this waste solidifying in the floor drains.

What measures are being taken to prevent such an occurrence when spills occur?

2 At what location does the crystallizer discharge to the circulating water system?

3.

What is the storage capacity for solidified waste at elevation 25 of the Waste Processing Building?

lI 4.

Where does the discharge from compactor exhaust? Does it have an effluent monitor if it exhausts to the environment?

5.

Please change Section 11.4 to address the capability of the system and the plant's comitment to meet state burial site requirements or justify not doing so.

6.

A portion of the line on sheet 2 of Figure 11.4-1 from the waste feed concentrates tank is heat traced.

It appears that the remainder of the line downstream of valve 1 1/2"-WS-V157 is not but should also be heat i

traced. Please provide a justification for omitting the heat tracing if it is not heat traced.

A similar comment pertains to the line from the chemical drain treatment transfer pump to the waste feed tank (heat traced Figure 11.4-1, Sheet 1) and the same line shown in Figure 9.3-12.

If they are to be heat traced then another line in location C-1 of Figure 11.4-1, Sheet 1, from the same pump to the waste concentrate tank should also be heat traced.

Other lines which should be heat traced or justification provided for not doing so include:

(a) SGB evaporator bottoms pump discharge to waste concentrate tank:

~

(Figures 10.4-7, Sh 1 and 11.4-1, Sh 1)

(b) Recirculation line frcm crystal 11zer recirculation pump to crystallizer vapor body and from crystallizer drain pump to waste feed tanks.

(Figure 11.4-1, SS 5) 7.

What dose rate is anticipated in the area where the asphalt will be stored?

8.

Do the various components and piping which contain radioactive slurries have flushing connections?

9/

Are the Seabrook tanks and equipment which use compressed gases for transport of resins and/or filter sludges vented directly to a plant ventilation exhaust. system which incorporates a HEPA filter?

10. How does the Seabrook vent design prevent liquid and solids from entering the plant ventilation system?

11. How much storage area is dedicated to dry wastes and packaged contaminated equipment? How much is allocated to solidified and dewatered wastes? Where are these areas located?

12. Section 11.4 does not address the supplementary guidance of SRP 11.4 for mobile solidification systems.

Please revise Section 11.4 or justify not doing so.

13. The process control program has not been provided for both the mobile and the in-plant solidification system. Please provide the program i

description.

14. In order to calculate the volume of wastes anticipated from the Seabrook Plant, the volume of waste (filter sludge) associated with filter in various processes is required. Please provide the waste volume associated with each filter element and the annual contribution of that filter element to the solid waste processing system.
