: 5. PURPOSE 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 flammability hazard of these chemicals must also be addressed (Ref.2).
CCNPP proposes to use a 35% hydrochloric acid solution, which will be stored in a 500 gal tank at the tank farm; however, the hydrochloric acid will be transported to the tank farm in a 5000 gal truck. The chemical habitability of the control room after a chemical release involving hydrochloric acid 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 config~u ration with the           1 inleakage points at the west road inlet plenum (Refs.3-4). Results indicate that this solution can  !
be transported to the tank farm in a 5000 gal truck 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% hydrochloric acid solution are as follows Peak Concentration                              !
Current Configuration        No Recirculation         16.1 ppm With Recirculation        16.1 ppm Modified Configuration       With Recirculation         10.9 ppm Toxicity Limit (IDLH) ,                               100.0 ppm                                   ;
Note that under the current configuration with the control room in the recirculation mode within 20 minutes post-accident and under the modified configuration with the control room in a perpetual rectreulation mode, 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 impairing 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.

7.TECIINICAL ASSUMPTIONS l'
The following technical assumptions were utilized in this work:
(01) Per Attachment F, a 35% Hydrochloric Acid Solution is stored in a storage tank of 500 gals capacity in the tank farm; however, the hydrochloric acid will be transported to the tank farm in a 5000 gal truck.
(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 hydrochloric acid solution, the 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 speed 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 5E+05 is laminar.
(07) The vapor pressure of the spilled material will be adjusted to the ambient conditions via the ideal gas law:                                                                                       .

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

The rate of mass transfer of a liquid imo 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 surface area, however, does not expand indefinitely as the above equation indicates. The maximum area of the spill in an unconfmed space is estimated from the initial volume by assuming a spill thickness ofI cm.                                      .

When exposed to the atmosphere, liquids with boiling points above the ambient temperature will evaporate by diffusion into the air. The main driving force is the vapor pressure difference, i.e.,
concentration gradient, between the lic uid phase and the air. The rate of a vapor diffusing into still air is computed from the Fickian c.iffusion equation in Ref.15 2

: 13. CONCLUSIONS Based on the spreadsheet results presented in Attachments D and E, use and storage of a 35%
Hydrochloric Acid Solution at the tank farm in a 5000 gallon truck does not present any control room habitability concerns at CCNPP.
The current chemical habitability calculation incorporates many assumptions which make these results conservative.
(1)thout wi           physical incapacitation of an average human. The regulatoryA maxim dictate a maximum concentration limit that could be tolerated           for 2without mutes    m, requirements physical   of Ref.2 i incapacitation of an average human. IDLH denotes Immediately Dangerous to Life and Health                I 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 ofroom A512.                                                                                  '
(4) The most conservative methodology is utilized: turbulent evaporation.
l l
Hydrochloric Acid Solution will not pose a flammability or explosion hazard, since the solution is non-flammable and non-explosive per Refs.5 and 10.
