13587-2-G01-105 DESIGN CRITERIA FOR INTERIM SOLID WASTE STAGING FACILITY 1.0 FUNCTION The Interim Solid Waste Staging Facility (ISWSF) is to be used for the collection and temporary storage of low level solid or solidified waste packages. All waste packages in the ISWSF are assumed to be completely prepared for shipment.
No operations except material handling are assumed for the ISWSF.
The Interim Solid Waste Staging Facility will be sized to acccamodate 6 months of waste generation from both Units 1 and 2 as shown in Table 5-1 without shipment for offsite disposal.
2.0 SCOPE The Interim Solid Waste Staging Facility will be a simple facility consistent with its passive function.
There will be a slab with curbs and a sump to contain any liquids released within the facility. A noncombustible roof will be supported on columns.
Electric power will be supplied to the facility for lights and utility outlets.
The facil-ity will have one truck bay to facilitate loading waste packages onto trucks for shipment.
There will be a fence completely surrounding the facility.
3.0 FACILITY DEFINITION 3.1 FUNCTION The Interim Solid Waste Staging Facility provides a location for the collection of waste packages.
It performs the passive functions of protecting waste packages from precipitation and providing a facility which eases loading of waste packages on trucks.
The Interim Solid Waste Staging Facility performs no active functions.
3.2 MAJOR COMPONENTS LIST - SEE SECTION 2.0, SCOPE l
l 3.3 INTERFACES i
There are six interfaces associated with this facility.
l1 (1) The facility must interface with the onsite material handling equipment which will be used to bring waste packages into the facility.
Material handling into and within the ISWSF will be done with forklifts.
There will be at least one ramp into the facility.
Page 1 Rev. 1
13567-2-G01-105 (2) The ISWSF must interface with trucks ano shipping casks used to transport waste packages offsite.
There will be one truck bay adjacent to the ISWSF, which will allow loading of a standard flatbed trailer or enclosed van by a forklif t.
Ramps will exist over the curbs.
(3) The ISWSF will be completely surrounded by an isolation fence.
On the east side, the isolation fence is also the station fence.
(4) An interface with an existing electrical system will be re-quired to provide power for lights and utility outlets.
(5) An interface will exist between the ISWSF and the existing plant to assure that fire protection and detection are ade-quate.
(6) An interface with the existing plant public address system will be provided.
4.0 FUNCTIONAL REQUIREMENTS 4.1 ACCESSIBILITY In addition to the access requirements identified in Section 3.3, Interfaces, there is a need for ready access within the Interim Solid Waste Staging Facility.
Access within the facility is required to assure tnat material handling operations proceed quickly to assure operator exposures are ALARA.
There may also be a need for temporary shield walls within the facility to achieve ALARA operator exposures.
4.2 MAINTAINABILITY This facility shall require no preventive maintenance for at least five years. The slab and columns shall be coated to the height necessary to
(
allow decontamination of the surfaces.
l 4.3 PERSONNEL Personnel will be needed in the Interim Solid Waste Staging Facility to do material handling.
The minimum number of operators needed to perform the activities will be assigned to assure that total exposure is ALARA.
Only those personnel actively involved in the material handling activi-ties should be inside the fence er.; losing the ISWSF.
a.4 SAFETY Waste stored in the Interim Solid Waste Staging Facility will be in a nondispersible form, since it will be a solid and contained within a sealed container.
Regulation 10 CFR 20.105 limits the radiation levels in unrestricted areas.
Regulation 40 CFR 190 further limits the yearly radiation dose to any member of the public due to all fuel cycle ac-tivities, including direct radiation.
Compliance with these regulations l
Page 2 Rev. O
13587-2-G01-105 will assure that the facility will not have an unacceptable impact on public health and safety.
The site's Radiation Protection Plan, which implements the requirements of 10 CFR 20.1(c), will assure that operator exposures associated with
~
the Interim Solid Waste Staging Facility are ALARA.
A dose rate of 0.3 mr/hr for an occupancy of no more than 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> per year (see Rtgulatory Guide 1.109) is used at the site boundary (river shoreline) to assure cc:pliance with 40 CFR 190.
A dose rate >f 0.6 mr/hr is used at the fence separating the ISWSF from areas surroundir.g it.
5.0 FACILITY DESIGN REQUIREMENTS 5.1 GENERAL REQUIREMENTS The input to the Interim Solid Waste Staging Facility will be packages of solid or solidified wastes ready for shipment.
The quantity and radiation levels cf the wastes from both Units 1 and 2 are presented in Table 5-1.
Nc activities on the waste packaocs other than handling will have to be performed in the ISWSF.
All counting, swiping, decontamina-tion, and weighing will be done prior to the transfer of n ackages to the ISWSF.
The Interim Solid Waste Staging Facility will allow separation of Unit 1 wastes from Unit 2 wastes.
5.2 CODES, STANDARDS, AND REGULATIONS 5.2.1 Federal 5.2.1.1 10 CFR Part 20, " Standards for Protection Against Radiation" 5.2.1.2 40 CFR Part 190, " Uranium Fuel Cycle Standard" 5.2.1.3 United States Nuclear Regulatory Commission Regulatory Guide 1.109 - Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I (Rev. 1, October 1977) 5.2.2 Industry The facility will be designed in accordance with the applicable portions of the following industry and state codes:
5.2.2.1 American Institute of Steel Construction (AISC), " Specification for the Design, Fabrication and Erection of Structural Steel for Buildings,"
l Nove ber 1, 1978 1
5.2.2.2 American Iron and Steel Institute (AISI), " Specification for the Design of Cold-Formed Steel Structural Members," 1968 Edition, with commen-tary dated 1970 and supple:ent dated 1971 Page 3 Rev. 1

5.3 INTERLOCKS AND ADMINISTRATIVE CONTROLS Administrative controls will be required to assure that no waste package with radiation levels exceeding those shown in Table 5-1 are trans-ferred to the ISWSF.
These controls should also assure that the smearable contamination on each package's outer surface is below the regulatory limit for shipping.
There will be no interlocks in this facility.
5.4 MATERIALS The slab and curb of the ISWSF will be concrete finished with epoxy.
The roof will be metal standing seam with factory-applied protective coating.
Shield walls will be either poured or filled block concrete.
All wall surfaces facing contaminated storage areas shall be finished with epoxy and the outside of the walls shall be painted with acrylic paint' Structural steel columns, where exposed to contaminated storage areas, shall be finished with epoxy.
All other steel columns and roof framing shall receive standard shop applied primer and field-applied protective finish.
All fencing materials shall be galvanized.
5.5 LAYOUT REQUIREMENTS 5.5.1 Location The location and size of the ISWSF is determined by
- number of contair.ers based upon 6 months storage (Table 5-1)
- space available
- configuration required for separation of Unit 1 and Unit 2 waste
- storage area requirements based upon pyramidal vertical stacking
- minimum clearance requirements to overhead power lines
- sufficient space for forklift operation Page 4 Rev. 1
13537-2-G01-105
- required topography to facilitate incorporation of the truck bays
- shielding requirements to meet ALARA and boundary dose con-siderations.
The location of the ISWSF also governs the radiation level of packages which may be stored there without shielding.
This is so since its location will establish the distance to the fence which nust surround the facility.
