8.3.2 Liquids 1.
Potentially radioactive liquid wastes are collected in underground tanks for discharge into the James River. A minimum of 40,000 gallons of storage space is available.
Process liquid wastes are collected and stored indoors in DOT-f approved containers suitable for offsite shipment for burial. Liquids may be stored outdoors for short periods of time' incidental to transfer or offsite shipment.

Concentrations of the mixtures of radioisotopes will be below those j
defined in Appendix B, 10 CFR 20, averaged over one year. Measurements are taken at or before the point of discharge to the James River.
f 3.* Storage tanks are inspected visually upon each tank voiding to en-f sure that there are no unsafe accumulations of special nuclear material.
4.
The fissile content of the waste tanks shall be less than 0.01 gm/ liter.
The tanks shall be analyzed (a) quarterly, (b) whenever emptied, (c) whenever an un-known quantity of fissile material has been released to the tanks.

Dry fissile vaste is stored only within the radioactive waste building. Fif ty-five gallon drt are normally used with a normal total amount of SNH in each drum less than 15 grams of fissile material.

These monitors are connected to a logic circuit that activates the building evacuation alarm when any two monitors trip. The mor.itors are connected to the building's emergency power system, ensuring alarm activation in the event of a failure of normal site power. Monitors r;.ay be removed, added, and relocated to meet the Center's experiment programs; therefore the above locations should not be considered permanent.

The quantities of material stored within the addition shall conform to those specified for Building J.
Dry waste containing Type A quantities of radioactive material (ref 10 CFR 71.4(g) per container or less and/or less than 0.5 grams of fissile material per container may be stored in the fenced, locked and paved area adjacent to Building J.
Waste containers shall be closed, metal containers suitable for offsite shipment.
3.7 Liquid Waste Disposal Facility The Liquid Waste Disposal Facility (LWDF) is shown in Figure 3-2.
The LWDF is a below grade " tank farm".
A schematic diagram of tank arrange-ments, piping and pumps is presented in Figure 3-14.
Potentially contaminated waste water is piped from material handling areas to specific tanks so that-the type of activity in any given tank can be anticipated. Each tank is pro-vided with piping for thorough mixing by air sparge.
The drain lines from each tank is located in the bottom of the tank to permit complete emptying.
Exceptions to this are the two 4000 gal waste tanks which have floating drains.
The rectangular tanks shown in Figure 3-14 are constructed of concrete. The interiors are treated with a water-proofing material.
The tops are of concrete and access to the tanks for cleaning, inspecting and sampling is gained through man holes.
The tanks indicated by circles on Figure 3-14 are constructed j
of steel. The 300 gallon tanks are stainless steel and are not provided with inspection ports. The 2000 gallon tanks are constructed of carbon steel, treated with an epoxy lining and are equipped with man holes for inspection.
A 10,000 square foot pond is located :pproximately 150 feet north-east of Building J.
This pond collects storm di tinage from Buildings B&C.

A.9.3.3 Liquid W st, 1.
Low-level radioactive liquid wastes are collected in under-ground tanks. Vastes are discharged to the licuid waste treatment plant at B&W's Naval Nuclear Fuels Division (NNFD).

The ratio of the sum of the compo-site materials shall not exceed 25% of the MPC values of Table I, Col,2, of 10 CFR20, Appendix B. for release to the NNFD waste treatment system. The limiting values in water shall be determined in accor-dance with the note-at the end of Appendix B, 10 CFR 20.
Process liquid wastes are collected and stored indoors. These liquid wastes are solidified and hand!.ed as dry waste prior to shipment for off-site disposal.
