5. PURPOSF/ I 10CFR50 App.A GDC.19 (Ref.1) requires that a control room be provided, from which actions can be taken to operate the nuclear power plant safely under normal conditions and to maintain it in a safe condition under accident conditions. Release of hazardous chemicals can potentially result in the control room becoming uninhabitable. Thus the NRC requires each utility to assess the habitability of the control room during and after a postulated external release of hazardous chemicals based on the chemical toxicity limit, vaporization rate, and the relevant atmospheric dispersion coefficients (Ref.2). The explosion and fiammability hazard of these chemicals must also be addressed (Ref.2).

Ecolochem, Inc. will use 35% hydrazine solution in the water treatment process. This solution will be stored in 375 gal tote bins at the tank farm, warehouse, and north service building (Att.F).

The chemical habitability of the control room after a chemical release involving hydrazine was determined based on in-house dispersion calculations and toxicity determinations for the current control room configuration with the inleakage points at the control room inlet and exhaust dampers and for the modified control room configuration with the inleakage points at the west road inlet plenum (Refs.3-4). Results indicate that this solution can be stored in a 35% solution at the tank farm, warehouse, and north service building without constituting a toxicological or fire hazard to the control room following a worst case accident for both the current and modified control room configurations.

The results of the toxicity calculations for a 35% hydrazine solution are as follows:

Peak Concentration (ppm)

Tank Farm Warehouse NSB Current Configuratio No Recirculation 0.88 0.25 2.80 With Recirculhtion 0.88 0.25 2.80 Modified Configuration With Recirculation 0.57 0.29 0.84 Toxicity Limit (IDLH) 80 80 80 Note that under the current and modified configurations, the peak control room concentration under worst case conditions is less than the IDLH toxicity limit, the maximum level from which one could escape within 30 minutes without any impainng symptoms or irreversible health effects.

The current calculation incorporates many assumptions which make these results conservative.

(1) A maximum concentration limit (IDLH) was utilized that could be tolerated for 30 minutes without physical incapacitation of an average human. The regulatory requirements of Ref.2 dictate a maximum concentration limit that could be tolerated for 2 minutes without physical incapacitation of an average human. IDLH denotes Immediately Dangerous to Life and Health and is defined as the maximum level from which one could escape within 30 minutes without any impairing symptoms or irreversible health effects (Ref.5). (2) For the current configuration the maximum control room intake flowrate of 8300 cfm is utilized. This value is twice the normal operating value (Refs.6-8). (3) The control room volume conservatively neglects dead spaces in the control room ceiling and the volume of room A512. (4) The most conservative methodology is utilized: turbulent evaporation.

Hydrazine will not pose a flammability or explosion hazard in the control room, since the peak concentration is a small fraction of the lower explosion limit.

7. TECHNICAL ASSUMPTIONS /

The following technical assumptions were utilized in this work:

(01) Per Attachment F, a 35% Hydrazine Solution is stored in a tote bin of 375 gals capacity in the tank farm, warehouse, or north service building.

(02) Per Ref.15 in a postulated accident, it is assumed that the entire container of the toxic substance ruptures.

(03) An average ambient atmospheric temperature of 30 C and pressure of 760 torr will be used in this calculation. Variation in these parameters shows insignificant impact on the results (Ref.16). TA=30 PA=1 (04) The chemical spill will be assumed to spread in a circular shape with the maximum radius determined by a spill thickness of I cm per Ref.15.

(05) Based on the characteristics of the chemicals, the following release mechanisms will be assumed: For the hydrazine solution, the turbulent mass transfer is the worst of three methodologies: diffusion in still air, laminar mass transfer, and turbulent mass transfer.

(06) For laminar and turbulent mass flow, a wind sped of one meter /sec is assumed. This is consistent with the wind tunnel methodology and the CCNPP data of Ref.B3. Note that per Ref.17 (p.265), a flow with Reynold's Number less than SE+05 is laminar.

(07) The vapor pressure of the spilled material will be adjusted to the ambient conditions via the ideal gas law:

VP(@T.) = VP(@Typ)

9. METHOD OF ANALYSIS This work utilizes three separate methodologies to calculate mass transfer from the spill site to the control room.

(1) The first methodology is diffusion in still air for spills in closed areas and for liquids with

. high boiling points. The method of analysis utilizes the algorithms of Ref.15 to derive the toxic gas concentration inside the control room.

'(1a) Calculation of the Diffusion Coefficient of an air / toxic gas system for dilute gases at low pressures per Ref.13 by the method of Wilke and Lee:

OMEGA = Collision integral The Lebas molal volume VB can be calculated as follows per Ref.13:

VB = 14.8*(C) + 3.7'(H) + 7.4*(O) + 9.1 *(O in Methyl Esters or Ethers)

+ 9.9*(O in Ethyl Esters or Ethers) + 11 *(O in Higher Esters or Ethers)

' CA04542 Rev.0 Page 15 (1b) Surface Area of a Spill Per Ref.15 -

r The rate of mass transfer of a liguid into the atmosphere is directly proportional to the surface area of the spill. Ref.15 approximates the initial shape of the liquid body by a cylinder, with the height equal to the radius of the base.

The liquid spreads quickly by gravity to a thin pancake on the ground. Its surface area may be '

estimated by the foi owing equation:

where SG = Density of the liquid (gm/cc) 2 g= Gravitational constant = 9.81 m/sec l t= Time (sec) _  !

The surface area, however, does not expand indefinitely as the above equation indicates. The maximum area of the spill in an unconfined space is estimated from the initial volume by  :

13. CONCLUSIONS Based on the spreadsheet results presented in Attachments D and E, use. and storage of a 35%

Hydrazine Solution at the tank farm / warehouse / north service building in a 375 gallon tote bin does not present any control room radiological habitability concems at CCNPP. Hydrazine will -

not pose a flammability or explosion hazard in the control room, since the peak concentration is a small fraction of the lower explosion limit.

The current chemical habitability calculation incorporates many assumptions which make these results conservative. ,

Extinguishing hiedia: If this material is afire or involved in a fire, do not extinguish unless the flow of material can be stopped. Use water in flooding amounts as fog, or alcoho! foam, carbon dioxide, or dry chemical to dilute spills to nonflammable mixtures and to disperse vapors.

Unusual Fire or Explosion llazards: Hydrazine is a severe explosion hazard when exposed to heat or by reaction with oxidizers. Its v_apor is exceptionally hazardous because once ignited it continues to burn by exothermic decomposition in complete absence of air or oxidant, ne vaport may also travel to an ignition source and Dash back

• Die combustion of hydrazine yields 148.6 kcal/mol(heat), nitrogen and water are products.

• nus material may also ignite spontaneously when in contact with porous materials such as wood, asbestos, carth, or cloth.

Special Fire-fighting Procedures: Since fire may produce toxic fumes, wear a self-contained breathing apparatus (SCD A) with a full facepiece operated in the pressure-demand or posiuve-pressure mode and wear a fully encapsulating suit. Apply water from as far a distance as possible. If fire becomes uncontrollable or if containcts are caposed to direct flames, evacuate for a 2500-ft radius. Cool containers with flooding amounts of water. Be aware of runoff from fire control methods. Do not release to sewers or waterways.

CCNPP Control Room Habitability, Inventory of Job No: 11865 Chemicals File: M I contacted Evelyn to establish the amounts of chemicals currently in use, and the chernicals (ETA) to be stored in the future at CCNPP. The following input was provided:

• 11ydrazine is procured in concentrations of 35% in a 350 gallon tote bins. This chemical will be located in Warehouse No. 3, the Tank Farm, and the North service Building.

• Morpholine is procured in concentrations of 99% in a 280 gallon tote bins filled only with 170 gallons of Morpholine. A total of eight totes four of which are full on site at a time. This chemical will be located in Warehouse No. 3, the Tank Farm. and the North service Building.

• Ammonia is purchased in concentrations of 28 30% and diluted to 11% in the tank. This chemical will be located in Warehouse No. 3, the Tank Farm.

• ETA will be procured in concentrations of 85% in a 350 gallon totes. This chemical will be located id Warehouse No. 3, the Tank Farm, and the North service Building.

The above information will be utilized in performing the analysis currently underway for the CCNPP Control Room Habitability by considering a chemical spill due failure of the largest container for each chemical.

Dear Jack,

Oh N

~ h4a d' y,hff ,

Attached are MSDS sheets for the chemicals and reagents that'we plan to use at the Calvert Cliffs Plant. The bulk chemicals used in the water treatment process are '

E hydrochloric ccid and hydrazine. The other MSDS sheets are for silica, carbon hydrazine, and dissolved oxygen test kit reagents.

y, We would like to store up to 1000 gallons of 20% by weight hydrochloric acid in

_ two 500 gallon polyethylene tanks in separate polyethylene containment basins. This "*

amounts to a maximum of 9206 pounilidacid 561ujf6ii of which 1800 pounds is hydrochloric acid. These chemicals would be stored underneath the RO trailer and surrounded by the trailer skirting. The acid solution would be drawn from the tank by suction to the metering pumps located inside the RO trailer. Should the acid line fail, the vacuum on the suction line would be lost and the acid would return by gravity to the storage tank. At 100 gallons per minute average product water flow rate, about 20 gallons of the acid solution would be consumed per day. The acid tanks would be refilled by hose from non-pressurized vessels on a delivery truck. A higher percentage of hydrochloric acid solution could be considered, but we prefer the 20% solution due to its low vapor pressure and fuming characteristics.

Hydrazine would be delivered in stainless steel tote bins, and would need a forklift to be changed out. The tote bins have a maximum volume of 375 gallons and we would only need one in service at a time. The solution in the tote bins is 85% by weight hydrazine and the total weight of hydrazine solution is 3210 pounds, of which 1125 pounds is hydrazine. The hydrazine solution will be drawn from the tote bin by suction in a manner similar to the acid system. At 100 gallons per minute average product water flow rate, about i gallon of hydrazine solution would be used per day. Due to the low volume of hydrazine used, we are trying to find out if hydrazine is available in smaller bins.

C ADI,5/i2 REV 0 PASE 63 j We are still researching the specl0cs on longer trailers to accommodate the space required for your instrument panel and silica analyzers. The design will be either a longer trailer or a separate enclosure.1 will get back to you with the details as soon as they are available.

Please call me at (800) 446-8004 if you have questions.
