5.0 DESCRIPTION

OF THE FACILITY 5.1 General The North Anna Power Station is located in Louisa County, Virginia on the southem shore of Lake Anna. The Station consists of two pressurized water reactors with associated steam side components and an adjacent construction site. Cooling water for the power generating facithy is drawn from Lake Anna and then discharged to the Waste Heat Treatment Facility (WHTE.

l The WHTF consists of a series of lagoons. Flow from the WHTF to Lake Anna is via a 1 1

submerged jet at the Circulatmg Water Outlet Structure. 1 1

The Station has oil storage facilities, as described in the following sections. Loss of oil from storage facilities could result in oil reaching Lake Anna or the WHTF, Oil reaching the WHTF would normally be retained in the facility because of the submerged discharge to Lake Anna.

This plan is for the power generating facility and the associated construction site.

5,2 Fuel Oil System

. He Fuel Oil System contains most of the fuel oil stored and handled at the plant site. This system consist of one 5.000 bbl fuel oil storage tank, two 50,000 gallon underground storage tanks and four 1,000 gallen storage day tanks. There are ten ready and standby fuel oil pumps located in the oil pump house.

All of the fuel oil tanks and pumpe with the exception of the 5,000 bbl fuel oil storage tank are located either underground or in seismically designed structures which also protect the equipment from conceivable tomado generated missiles. Underground fuel oil lines are coated and wrapped to protect against corrosion.

The 5.000 bbl above ground fuel oil tank is enclosed by a concrete dike which is sized to contain the capacity of the tank. A drain dump inside of the diked area is connected to the :.ard drainage system via a Post Indication Valve which is kept closed. Storm water trapped ins.de the dike generally seeps into the ground. However, the Post Indication Valve can be opened to allow uncontaminated storrn water to enter the yard drainage system. If the storm water is contammated with oil, the water is pumped into a tank tnick and treated in the oil separator er -

oil absorbent mats are used to absorb the oil from the waste water, prior to discharge.

Two sump pits with drain pumps and 300 gallon drain tanks are located in the oil pump hee to collect any oil that could be spilled. When the drain tanks are partially full, an alarm signaj a

, transmitted to the control room. The drain tanks are pumped out to a tank truck for final disposal. Pumpout of the drain tanks should occur less than once per year.

ADM.D31

• PAGE%FM-shy' 06-01 92 5.2 Fuel Oil System (continued)

The fuel oil unloading area is equipped with a deep sump pit which collects runoff and oil spill from the tmck unloading area. De flow from the deep sump pit is routed to the oil separator (see Subsection 5.5). A qualified Virginia Power operator will obsen e the tmek and driver at all times and ensure that, in the event of a oil spill, appropria:e steps are taken to contain, remove, and prevent ftuther discharges. Also, signs will be posted with the following notice:

" Notice to Truckers: Check to be sure all valves are closed and hoses disconnected before moving your tmck away "

Additionally, thett are two above ground tanks associated with the five protection diesel generators and a 500 gallon below ground tank for the security emergency diesel generator located inside the protected area. '

5.3 Lubrication Oil System he lubrication oil system is located in the Turbine Building. It supplies lubricating oil for the turbine-generator bearings, high pressure oil for turbine control and seal on for the generator.

The lubrication system has two 16,000 gallon storage tanks for both generating units and one 14,000 gallon lube oil reservoir per turbine generator. Each unit has a lobe oil conditioner with a storage capacity of 2,000 gallons.

The two 16.000 gallon tanks are enclosed in a fire-proof room which can contain the entire contents of the tanks. Here am no drains in this area. De 14.000 gallon reservoirs plus a 200 gallon electroh>tiraulic oil reservoir are located inside a concrete dike which can contain the entire contents of the reservoir. The diked area has a floor drain which is controlled by a normally closed valve. The drain discharger, to the lower level of the turbine building. Any oil l allowed to drain fmm this area u ould be caught in barrels and transferred to the waste 00 storage area. The oilconditioner is surrounded by a sump. The sump has no drain ar.d can accumulate oil spillage and the entire contents of the ou conditionerin case of rupture.

Lubricating ou is delivered to the Station by tank tmcks. The hose connections are located inside of the Turbine Building. Any oil spilled inside the Turbine Building will go to one of three sumps (see Subsection 5.4) and eventually to the oil separator (see Subsection 5.5).

- 5.4 Turbine Building and Yard Drainage System Tne Tu-bine Building floor drains for Units I and 2 drain to or.e of three sumps. Each sump is equipped with two small skimmer pumps (100 gpm) that pump to the oil sepnator and three large pumps (1300 gpm) that pump directly to Lake Anna. Und:r normal c peratmg conditions, the large pumps are not used and all flow goes to the ou separator. However, under cenain conditions the smaller pumps cannot handle the flow and the larger pumps must te used. The level switches of the large pumps are set to shutdown the pumps before a low levelis reached, thereby preventing oil that is floating on the surface from being pumped to IAe Anna.

In the case of an oil spul in the Turbine Building, the large pumps would be shutdown. The four diesel generator rooms and auxiliary boiler room floor drains are routed to the No. 2 Turbine Building sump. Each diesel generator room has curbed entrances to ensure that any leaking oil is couected by the floor drains.

The yard drain system on the east and nonh sides of the turbine building drain to the main lake on either side of the screenwed stmeture. The yard drainage system for the south side of the Station (contamment side) drain into the WHTF adjacent to the Circulating Water discharge point. The primary sources of oil contaminated drainage into the yard drainage system are the Service Building Warehouse, Vacuum Pnming Pump House, Intake Structure Control Hous-and the Auxiliary Feedwater Pump Hot.ses for Units 1 and 2.

5,5 Oil Separator A ccrrugated plate oil separator is installed in the ground near the Turbine Building just nonh of the fuel oil unloading area. The oil separator is designed to remove all oil droplets 70 microns and larger at a flow rate of 200 gpm from waste water containing oil with a specific l gravity of 0.95 at a temperature of 70'F.

The pnmary sources of oily water to the oil separator are the turbme building sumps mentioned -

in Su'esection 5.4 and the floor drains in the machine shop.

5.6 Gasoline and Diesel Fuel All gasoline used at Nonh Anna is unleaded and is stored at two locations: 1) outside the l

! security fence adjacent to the Administrative Annex (Warehouse #2) in two underground taris (3.000 gallon and 1,000), and 2)in front of the Maintenance Garage in a 10.000 gallon fiberglass tank.

l All diesel fuel used on site is stored in a 10,000 gallon fiberglass underground tank in front er the Wintenance Garage.

5.7 Waste Oil Storage Facilities Any waste oil reclaimed by Virginia Power is placed in norage. When enough oil is accumulated, the reclaimed oil is sold to vendors. There are three facilities for storage of waste oil, The reclaimed oil from the Station operations is stored in a 1.500 gallon above ground tank.

This tari is located inside the oil storage ouilding and has a concrete curb around it to contam any spillage.

The reclaimed oil from the hf aintenance Garage is stored in a 550 gallon underground waste oil storage tank adjacent to the garage.

Waste oil separated from the Waste oil Separator is transferred to a 5.800 gallon underground waste oil storage tank. This tank is located inside the fence adjacent to the Fuel Oil Pumping Station.

At each location, the volume of waste oil is monitored and provisions are made to ensure adequate storage capacity is available.

5.8 Transformers There are several groups of transformers located at North Anna. All of these transformers were inspected during the summer of 1981 and it was found that none of them would be considered PCB.

There are four reserve Station transformers located at thc cooling water intake stmcture. Etree of these are in use, the fourth one is a spare. Each transformer is ated at 18 MVA and the three operations units are enclosed in a concrete container to pavent accidental spillage.

There are three main Station transformers (general step-up transformers) plus one spare, for each generating unit. Each transformer is rated at 330 MVA and each operational unit is enclosed in a concrete container to prevent accidental spills.

Also there are three Stadon service transformers for each generaung unit, rated at 15 hfVA cacn that are also enclosed in concrete containers to prevent spills.

Additionally, there are transformers located in the switchyard. These units are located away from the lake and are placed on a gravel cover as is found in most switchyards.

1 ADM.2031 1 PAGE ROF-tS r/[y 0641 92 5.8 Transformers (continued)

Under normal conditions, personnel from Virginia Power's Central Division inspect and perform all maintenance on all transformers. In the event of an emergency that could lead to a spill, the Station personnel will undertake emergency actions to contain any spill, prevent damage to equipment and the environment, and notify the Central Division of the situa: ion.

Any permanent or long range actions will be carried out by personnel from the Central Division.

5.9 Main Dam Emergency Diesel Fuel Oil Tank The two above ground 750 gallon main dam emergency fuel oil tanks are enclosed by a concrete dike which is sized to contain the capacity of both tanks. Here are no floor drains in this area: therefore, the oil cannot reach any storm drains. De floor is indented in one comer so that a sump pump could be placed in the aret to remove all of the oil in the event the tanks loose their integrity.

5.10 Contaminated Oil Oil which has become radioactively contammated is temporarily stored in the Clar3er Building. This oilis stored in 55 gallon drums untilit can be processed by Herith Physics.

The !!, ar is sloped and contams drams so that any leakage will be treated as a radioactively contammated liquid.

5.11 Temporary Fuel or Oil Storage Temporary tanks, including tanker trucks, may be used from time to time to provide supplemental fuel or oil storage at the Station. Normal gasoline and fuel oil deliveries are not included.

I Ms. Cathy Harris June 19, 1992 Page 2 In order to preclude future recurrence of this incident, increased surveillance of tank filling operations and the equipment involved will be implemented. No further remedial actions are necessary as it is expected that no residual hydrazine exists in the discharge to the canal or in the Waste Heat Treatment Facility.

Hydrazine has been previously identified as a potential constituent of the station's discharge. However, in this event, the spill route was into the station discharge canal, where adequate treatment was provided, and the hydrazine was not released to the enviro. ment. The notifications above were made as a precautionary measure due to the nature of the spilled substance and its potential for detrimental effects.

Should you desire additional information or have any questions about his matter, please contact Daniel James at (804) 273-2996.
