Dear Dr. Sherwood:
SUBJECT:
GENERAL ELECTRIC TOPICAL REPORT, NED0-21059, "BW' RADIOACTIVE WASTE TREATMENT SYSTEMS" We have reviewed the subject topical report and find that we need additional information to complete our review. The specific radwaste system design and interface information that we require is enclosed.
Please inform us of tne date by which you will be able to provide the requested information.
Sincerely,

You indicate that the requirements concerning quality control, welding, constructien, system testing, cleaning and flushing, perfor:ance tests, and, functional requirements of the liquid effluent monitor, are items whose " Applicability must be confirmed by the applicant," since the apolicant must confirm what is within his scope. You should state more clearly what components and systems are within the scope of NED0-21059.
Otherwise it will be necessary to evaluate the above items on a case-by-case basis for applications referencing NED0-21059.
E.
For the P& ids which you supolied in resconse to Item 320.1 you should' indicate interfaces between the liquid and solid system and all BOP interfaces and the gaseous waste system or plant ventilation system.
Each interface should be listed along with pertinent physical information such as line size and safety class, pressure, temperature, flow rate, batch size, and radioactivity concentration.
. water tanks and pumps, spent resin tank and pump, chemica1 addition tanks and pumps, evaporator distillate tanks and pump, concentrated waste tank and pumps, detergent waste tank; and pumps, anti-foam tanks, cement silo, caustic. tank and pump, and piping and valving in the radwaste system.
You should indi-cate who is responsible for the scope of supply of these components. 'Otherwise it will be necessary to evaluate the design capacity, system design and interface criteria for these components when an application referencing NED0-21059 is made.
B.
It is unclear whether the process and effluent radiation monitors are within GE's scope of supply.
If the process and effluent radiological monitoring system is within GE's scope of supply provide additional information as required in Standard Review Plan 11.5, Rev.1 Section II concerning the provision to monitor and sample the effluent pathways from the liquid sys tem.
You should provide for each nonitor within the GE scope of supply a description of the monitor, detector type, location of readouts, alarms and automatic control function in accordan;2 with the requirements of appropriate portions of Table 1A and 1B of SRP 11.5, Rev.1.
C.
Since the radwaste building design ari construction are not within GE's scope of supply, NED0-21059 should state as inter-face information that the seismic design of the building
. (2) System Performarce (a)
Identify equipment (interl7eks, alarms, monitors, etc.) which are required to be functional before pec:assing can begin; (b)
Identify administrative controls, instrumentation, or equipment 'aatures to assure that operating pro-cedures will be followed; (c)
Identify the processing steps to assure that the solid waste system is being operated within the boundary conditions established by the process parameters; (d)
Indicate that the plant ocerator will provide assur-ance that the process is run within the process parameters boundary conditions. Appropriate records should be maintained for individual batches showing conformance with the established parameters.
320.17 Your responses to Item 320.13 con:erning interfaces 's unclear.
Particularly, provide information on the following:
A.
You indicate what components in the liquid and solid waste systems are within GE's scope of supply. Certain components are not listed, in particular, the collection tanks and pumps, body feed tank and pump, filtrate tanks and pumps, excess
. it is reasonattly assumed that complete solidifica-tion will occur. These process parameters should include, but not be limited to, for each type of influent waste:
pH, water content, temperature, effect of various contaninants such as oil content, detergent content, lab chemicals and non-depleted iod exchange resins,
- tio of cement to influent waste, type of cement to be used in each case, and the ratio of cement to sodium hydroxide additive; (b) The basis upon which the process control parameters are chosen should be given. The process control program should be based on tests performed with simulated waste formulations based on the expected inputs and the parameters listed in (a) above; (c) The requirements for sampling of the waste input to the solid waste system as it relates to the process control program prior to processing to assure a sat-isfactory solidified p' oduct. Where will the wa'ste be sampled? Discuss how the results of the sampling will be analyzed and used as operational considers-tions in the process control program.

. A.
Yo'ur response to Item 320.3D is unacceptable.
You should indicate the processing capacity of the SRS, i.e., the number of containers per day which the system is capable of proces-sing, filling, and storing, and compare with the expected total waste input to the system.
B.
In your response to Item 320.9 you did not discuss the method of solidification of activated charcoal and HEPA filters.
Indicate the disposition of these wastes in accordance with Branch Technical Posit:on ETSB 11-3, Rev.1 C.
Your responses to Item 320.9C and 320.12D do not contain enough information concerning the orocess control program which will be used with the solid waste system.
You should provide information concerning the process control program in accorcance with Branch Technical Position ETSB 11-3, Rev. I and, in particular, provida the following information concerning the process control program:
(1) Process Control Parameters (a) Depending cn the type of waste (bead resins, pow-dered resins, diatomaceous earth, evaporator bottoms, sodium sulfate solutions, etc.) to be solidified, indicate the process parameters which will be estab-lished to provide boundary conditions within which

F. Cardile 320.0 EFFLUENT TREATMENT SYSTEMS BRANCH 320.14 You indicate in your response to Item 320.5(2)C that certain (11.2.3) components not 41,scussed in Table 11.2.1 will meet the guide-lines of Table 1 of Regulatory Guide 1.143 (formerly Branch Technical Position ETSB 11-1). You should indicate that these items w'il mcet all of the design guidelines of Regulatory Guide 1.143.
3d0.15 You indicate in your response to Item 320.3B that there are no
(.1.2) alternative treatment paths for chemical lab drain wastes other i
than the detergent evaporator. As a result of detergent evanora-tor downtime, this will result in untreated releases of this source approximately 1 day per week for a single unit system, and 1.5 days per week for a shared unit (using the input flow rates of NUREC-0016, Rev.1).
You should provide additional information concerning potential treatment of this source.
Otherwise the source term which we use in applications referencing NED0-21059 will include the input from this untreated release.
320.16 Your responses to our questions on the solid waste are not (11.5) sufficient. Provide the following additienal information con-cerning your solid waste system:
