Each tank is sampled and sludge is not allcwed to accumulate in category B tanks. Only cou-taminated liouid is permitted in the tanks with concentration never exceed-ing 0.01 grams fissile / liter; more than 15 years of experience with these and.similar tanks has demonstrated no problems.
Liquid wastes are under positive control and surveillance of health physics.
3.6.2 Dry Wastes
' Dry radioactive waste is stored, avaiting shipment for offsite disposal, in Building J (Figure 3-21), the temporary addition to Building J (FAgure 3-24) and the outside storage area (Figure 3-21).
Waste stored in Building J shall be in closed DOT or NRC approved containers suitable for offsite shipment. These containers may be stored out doors for short periods of time incidental to transportation. Waste stored in the Building J addition and in the fenced out door storage area shall be in closed DOT or NRC approved metal containers suitable for offsite shipment.
All containers may not be stored with overpacks if such are required for transportation.
Building J provides 1400 square feet of storage space. Greater than Type A quantities of radioactive material (refer to 10 CFR 71.4 (q) per l
container and/or greater than 0.5 grams of fissile material'per container shall be stored within Building J.
All Pu waste shall be stored indoors. The l
building is provided with a snmke detector that alarms in the Building B health physics area and the guard station a the Naval Nuclear Fuels Division, an air sampler, a criticality monitor and a personnel survey instrument. Two shicided areas are provided for storage of intermediate and high level waste.
The temporary addition to Building J provides 178 square feet of storage space. It is constructed of solid, unmortared concrete block, j
The three outside walls shall consist of four courses of block (approx. 4 ft.
thick) and three courses (approx. 3 ft. thick) of block abutting Building J.
The addition is provided with exhaust ventilation through ducting which con-nects Building J with the addition there by permitting the smoke detector and air sampler in Building J to serve both. The addition is provided with metal roof which is hinged to Building J, capable of being lock and provided with License No.

pravid:d with side pancis which permits the roof to fit flush with ihe blocks. A curbing will be placed on the approach side of the addition to prevent a loading vehicle from accidently c>.tacting the exterior block wall. At least two individuals will be involved in transferring waste con-tainers into or out of the addition to prevent the container or handling boom from contacting the exterior block wall. The quantitics of material stored within the addition shall conform to those specified for Building J.
Dry vaste containing Type A quantitics of radioactive material (ref to 10 CFR 71.4 (q) per container or less and/or l'ess than 0.5 grams of fissile material per container.except Pu,may be stored in the fenced, locked and paved area adjacent to Building J.
Waste containers shall Le closed metal containers suitable for offsite shipment.
Radiation levels at the boundry of the restricted area (the outer fence surrounding the waste storage area) shall not exceed the limits specified in 10 CFR 20.105 (b).

8.3.2 Liquida 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 approved containers suitable for offsite shipment for burial. Liquids may be stored outdoors for short periods of time incidental to transfer or offsite shipment.
~
2.
Concentrations of the mixtures of radioiso; opes will be below those de-fined in Appen' dix B,10 CFR 20, averaged over one year. Measuremen:s are taken at or before the point of discharge to the James River.
3.
Storage tanks are inspected visually upon each tank voiding to ensure 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) auarterly, (b) whenever emptied, (c) whenever an unknown quantity of fissile material has been released to the tanks.
8.3.3 Dry Waste Dry waste containing greater than type A quantities (refer to 10 CFR 71.4(q), per container, andhr greater than 0.5 grams of fis'sile material, per container, shall be stored indoors in closed containers suitable for offsite shipment. Pu waste shall be stored indoors.
Containers may be stored out of doors for.short periods of time incidental to transfer or offsite shipment.
All containers may not be stored with overpacks if such are required for tran-sportation.
All other dry waste containing licensed material may be stored in the fenced, locked and paved outside storage area, in closed metal containers suita-bic for offsite shipment The storage area is under positive control and sur-veillance by health physics, and the area will receive at least a quarterly vis-ual and radiological inspection. This is adequate since waste is not stored for long pericds of time.
