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 uses a 40% Dimethylamine (DMA) Solution in the secondary system for boiler water treatment. This toxic material will be stored in 350 gal stainless steel totes located on the 12' turbine building (TB), the 12' north service building (NSB), and the tank farm (TF - Ref.19, Att.F). The chemical habitability of the control room after a chemical release involving 40% Dimethylamine Solution 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 40% Dimethylamine Solution can be stored at the 12' turbine building,12' north service building, or tank farm 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 40% Dimethylamine Solution are as follows: Peak Concentration (ppm) 12' TB 12' NSB TF Current Configuration No Recirculation 767 124 39 Modified Configuration With Recirculation 31 14 9 j Toxicity Limit (IDLH) 2000 2000 2000 Note that under the current and modified configurations and for all source locations, the peak i control room concentrations under worst case conditions are less than the IDLH toxicity hmit, j the maximum level from which one could escape within 30 minutes without any impairing symptoms or irreversible health effects. Dimethylamine will not pose a flammability or explosion hazard in the control room, since the control room concentration will always be much less than the flammability limit in air. The current calculation incorporates many assumptions which make these results conservanve. (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 i 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 l spaces in the control room ceiling and the volume of room A512. (4) The most conservative methodology is utilized: instant flashing of the entire quantity of Dimethylamine. (5) The 0-2 hour atmospheric dispersion coefficients are used for the duration of the accident. I

7. TECHNICAL ASSUMPTIONS The following technical assumptions were utilized in this work:

(01) Per Att.F, a 40% Dimethylamine Solution is stored in a tote bin of 350 gals capacity in the 12' turbine building,12' north service building, and tank farm. (02) Per Ref.15 in a postulated accident, it is assumed that the entire container of the toxic substance ruptures. (03) Based on the characteristics of Dimethylamine, all of the spilled material is assumed to immediately evaporate due to its low boiling point. (04) It is conservatively assumed that the spill occurs at the 45' level and for the turbine building at a point closest to the control room inlet. .l l j

r-CA04541 Rev.0 Page 13 9.METIIOD OF ANALYSIS This work utilizes the following methodology to calculate mass transfer from the spill site to the control room. (01) This methodology is for liquids with boiling points less than the ambient temperature. For this case the entire inventory of toxic material is assumed to flash to a gaseous state in t seconds. The vapor density outside the control room is thus govemed by the following equations. VD = (M0/t)*ADC (gm/m') PPM = (24500/MB)*VD where M0 = Inital mass ofliquid (gm). t = Flash time (sec) ADC = Atmospheric dispersion coefficient (sec/m3) MB = Toxic gas molecular weight (gm/ mole) The maximum concentration inside the control room can be readily calculated via the following: VDC = VD*(1.-exp(-FCR/VCR*t/60))(gm/m') where FCR = Control room inflow (cfrp)) VCR = Control room volume (ft t = Flash time (sec) Using a first order expansion of the equation for VDC as t goes to zero, the maximum concentration inside the control room can be readily obtained: VDC = MO*ADC*FCR/VCR/60 (gm/m') The total mass of the liquid can be calculated as follows: M0 = Q*QF*SG*3785.422 gm where Q = Storage quantity (gal) QF = Volume fraction ofliquid or weight fraction of solid SG = Specific gravity (gm/cc) (02) Explosion and Flammability Limits: Comparison of the maximum concentration of the relevant toxic chemical concentration inside the control room should yield a limiting value with which to compare against the explosion and flammability limits. 1 1 \\ l

12. RESULTS CCNPP uses a 40% Dimethylamine (DMA) Solution in the secondary system for boiler water treatment. This toxic material will be stored in 350 gal stainless steel totes located on the 12' turbine building (TB), the 12' north service building (NSB), and the tank farm (TF - Ref.19, Att.F). The chemical habitability of the control room after a chemical release involving 40%

Dimethylamine Solution 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 ;)lenum (Refs.3-4). Results indicate that this 40% Dimethylamine Solution can be stored at tae 12' turbine building,12' north service building, or tank farm 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 40% Dimethylamine Solution are as follows:' Peak Concentration (ppm) 12' TB 12' NSB TF Current Configuration No Recirculation 767 124 39 Modified Configuration With Recirculation 31 14 9 Toxicity Limit (IDLH) 2000 2000 2000 l E

f-L CA04541 Rev.0 Page 17 d

13. CONCLUSIONS Under the current and modified configurations and for all source locations, the peak control room concentrations under worst case conditions are 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. Dimethylamine will not pose a flammability or explosion 3azard in the contml room, since the control room concentration will always be much less than the flammability limit in air.

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 mmutes 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: instant flashing of the entire quantity of Dimethylamine. (5) The 0-2 hour atmospheric dispersion coefficients are used for the duration of the accident. l L i i i I i

In c meeting on C/8/98, I was asked to detenning tha appropricts precautions for =AA4 32 2-liter containers of 40% dimethylamine to water to make a 3%'so".ution. The =4-4T operation will take place outside. My rarv====adm e 4 t= = are as follows: . The area anast be cordoned off. with Danger flagging. . An eyewash and water for rinsing (i.e., a hose or showpr) must be present in the area. . At a minimum, workers inside the cordoned off area must wear full j facepiece airline respirators, poly-coated Tyvek disposable coveralls 1 - (BGE Stock No. 66117), and neoprene (BGE Stock No. AC707) or butyl rubber gloves. . Air sampling must' be coortucted for dimethylamine. I have ordered special detector tubes for _ collecting air samples during the chemical transfer. Please put me on the list to be notified when the work is scheduled. . Combustible gas indicator caeasurements must be made during the pouring. If J the levels exceed 10% of the I.FL, local exhaust ventilation must be used to disperse the vapors. . Procedures for handling a spill must be determined in advance. Other safety concerns, especially flammability, have or will be addressed by Bill Freesland. e Glih i i i C A0li5 41 REV 0 P A6E 8
