1 Attschmsnt to TXX-89221 April 28, 1989 Page 1 of 6 RESPONSE TO NRC QUESTION - CHAPTER 12 RADIOACTIVE AIRBORNE CONCENTRATIONS QUESTION #2:

The following are several apparent discrepancies noted in the data presented in Table 12.2-26." Radioactive Airborne Contamination."

Verify the results listed in Table 12.2-26.

If the bases for the input data for the airborne concentration calculations is not NUREG-0017 - GALE code, then describe in detail the bases for the input parameters used.

a.

Table 12.2-26 sheets 6 through 14 contain calculated airborne concentrations for radionuclides in nine rooms and corridors in the safeguards building.

Although Table 12.2-25 lists very different calculational parameters for these areas, the results for each of these nuclides are the same for all nine areas (allowing for some round off error).

b.

The input parameters are listed in Table 12.2-25 sheets 14 and 15 for the turbine building basement and mezzanine, respectively.

Comparing these with the results of airborne Tritium (H3) for those areas (Table 12.2-26 sheets 16 and 17), seems to indicate that increasing the leak rate about 2.5 times (in rooms of about the same size and ventilation flow rate) increases the H3 airborne concentration by 37 orders of magnitude.

Also, justify it design that has.5 MPC of H3 on the turbine building mezzanine during normal operation.

c.

Table 12.2-26 sheets 23 through 31 have fifty-three (53) incorrectly listed as the atomic number for Br, Co, Rb, Sr, Mo, and Cs.

RESPONSE #2:

Potential airborne concentrations in buildings and various areas throughout the Comanche Peak plant have been calculated.

A discussion of the assumptions, key parameters (including those parameters that differ from NUREG-0017, Revision 1), methodology, and results follows.

Specific responses to Question items a, b, and c are addressed in the results section.

Calculations will be approved and available for review on site by May 20, 1989.

-Leakage from the Chemical Volume and Control System (CVCS) is assumed to be the primary contributor to the radioactive airborne concentrations in the Safeguards and Auxiliary Buildings.

Leakage from the Residual Heat Removal System (RHRS) is also included for shutdown conditions when calculating airborne concentrations in rooms or areas.

Both the CVCS and RHRS are assumed to contain reactor coolant.

Since the leak rates provided for the auxiliary building in NUREG-0017 apply to both the Safeguards and Auxiliary Buildings at Comanche Peak, the leak rates have been prorated equally between the buildings for average building concentrations or among individual rooms for room concentrations based on the number and type of leakage sources (e.g. valves, pumps, flanges) (Enclosure, Table 1).

No purging, venting, or pressure relief of the Containment Building is assumed.

Prior to accessing the Containment Building for-brief periods during normal operation, the Containment Air Cleanup System may be operated and is designed to reduce airborne radioactivity levels.

Evaporation from sumps is assumed to be enveloped by releases from the primary system contributor to airborne concentrations.

PARAMETERS Release rates from NUREG-0017 were used to determine the leakage of iodines, noble gases, and particulate to the Auxiliary, Safeguards and Fuel Buildings.

Leak rates from NUREG-0017 were also used for the release of noble gases and iodines to the Turbine Building.

Noble gas and particulate leak rates from the Reactor Coolant System to the containment Building were assumed f x be one gallon per minute during normal operation, whi,3 is consistent with the NUREG-0017 value.

Iodine leak rates furing normal operation and shutdown were obtained from NURE0 <J17.

The NUREG-0017 leak rate for tritium was used in the calculations.

Forty curies of tritium are assumed to originate from liquid releases, based on 10CFR50, Appendix I, leakage assumptions.

Fifty percent of the

Att5 chm:nt to TXX-89221 L

April 28, 1989 Pase 3 of 6 l

remaining tritium is assumed to reside in the Fuel Building, 32 percent is prorated between the Auxiliary and Safeguards Buildings, and 18 percent is assumed to reside in the Containment Building.

During normal operation, the air density within containment is used to determine the effective concentration of tritium based on a relative humidity of 50 percent.

The shutdown concentration is the difference between the total and normal operation concentrations.

During refueling operations, the tritium concentration in the Fuel Building is assumed to be two times the normal operation concentration (NUREG/CR-0715).

Source terms for the reactor coolant and the secondary side activities were based on the "American National Standard Source Tern Specification" (ANS-18.1, ANSI N237-1976).

The decay of iodines to noble gases is included in the calculation of average building concentrations, which increases the noble gas concentrations.

Partition factors for iodines are included in the NUREG-0017 normalized release rates.

Partition factors for particulate are assumed to be included in the average of release rates presented in NUREG-0017.

The partition factor for noble gases is 1.0.

For particulate in containment, the removal factor was assumed to be 0.999.

This factor was obtained from the " Instrument Society of America Standard for Light Water Reactor Coolant Pressure Boundary Leak Detection" (ISA-S67.03, 1982).

Decontamination factors are assumed to be included in the leak rates obtained from NUREG-0017.

Volumes used in the calculation of average radioactive airborne concentrations in each building are as follows:

6 3

Containment Building 2.985x 0 t

Auxiliary Building 1.9x10 ft3 Safeguards Building 1.1x10 ft3 Fuel Building 1.3x10 ft 3 Turbine Building 2.8x10 ft Volumes in various rooms throughout the Safeguards and Auxiliary Buildings are provided in the Enclosure, Table 1.

Att5chmsnt to TXX-89221 April 28, 1989 Page 4 of 6 Ventilation flow rates used in the calculation of average radioactive airborne concentrations in each building are as follows:

Containment Building 30,000 scfm (shutdown)

Auxiliary Building 90,600 scfm Safeguards Building 26,000 scfm Fuel Building 36,000 scfm Turbine Building 275,000 scfm During normal power operation, the Containment Building is not purged, the containment Air cleanup System is only operated prior to brief containment entries, and t'a pressure relief vent is used only as required.

Therefore,-a ventilation flow rate of zero is assumed for the containment Building.

~he Turbine Building ventilation flow rate could be as high as 613,000 scfm, if all of the wall ventilators are operating.

Ventilation flow rates in various rooms throughout the Safeguards and Auxiliary Buildings are provided in the Enclosure, Table 1.

METHODOLOGY Radioactive airborne concentrations were calculated assuming Comanche Peak Unit 1 operation.

Adjustment factors are provided for two unit operation.

Average building concentrations represent conservative estimates during normal operation and shutdown conditions for boC1 unrestricted and occupational access areas (Radiation Zones I and II).

Examples of these areas include corridors, mechanical or electrical equipment' areas, diesel generator rooms, or any area that is accessible 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> / week and 50 weeks / year.

These estimates are conservative, since leakage from rooms with potentially high airborne concentrations are assumed to mix with the low radioactive airborne areas to yield a net increase in the expected values.

Room or area concentrations are also provided for locations in the Auxiliary and Safeguards Buildings where potentially high airborne concentrations could exist during normal operation or shutdown.

Equili" tum concentrations are reported for the buildings and rowas.

REST fS The average building concentrations and fractions of Maximum Permissible Concentrations (MPC) for both normal operation and shutdown are presented in the Enclosure, Tables 2 and 3, respectively.

For the Safeguards, Auxiliary, Fuel and Turbine buildings (and, hence, normally accessible areas),

the concentrations are a small fraction of MPC during normal operation.

In containment, the total MPC for normal operation is potentially much greater than 1.0 MPC.

Use of a self-contained breathing apparatus, if necessary, and the potential use of pressure relief (i.e., purge) in containment will greatly reduce the quantity of radioactive i

material inhaled by a worker when Containment Building entry is required.

During shutdown and refueling operations, the potential concentrations in the Auxiliary and Turbine Buildings are a small fraction of MPC.

The tritium concentration in the Containment and Fuel Buildings is the primary contributor to the MPC fraction.

Since these concentrations are based on conservative assumptions (i.e., spent fuel pool exhaust fans or other removal mechanisms were not assumed), the actual concentrations should also be a small fraction of MPC.

The primary contributors to the Safeguards Building MPC fraction are I-131 and I-133.

During normal operating and shutdown conditions, rooms with the highest potentially radioactive airborne concentrations include valve, heat exchanger, volume control tank, and pump rooms containing CVCS leakage and RHRS leakage (shutdown only).

Rooms with concentrations greater than 1.0 MPC are all in-Radiation Zone IV and V areas which have restricted access (if measured radiation levels are high), and ventilation flow is directed to the Primary Plant Ventilation System (PPVS).

All Radiation Zone IV or V rooms that were analyzed have ventilation flow paths directly to the PPVS, with the exception of Room 80.

Assuming that the radioactive airborne concentration is only due to the sources within the room, the potential concentration in Room 80 is greater than Room 31.

Since the ventilation flow path from Room 80 is to Room 81, the net concentration in Room 81 will increase.

This is the preferable flow path, since Room i

l 80 is a Radiation Zone IV room and Room 81 is a Radiation l

Zone V room.

The potential radioactive airborne concentration in Room 209 is less than 1.0 MPC and is in a i

Radiation Zcne III area where limited access is controlled (if measured radiation levels are high) and the ventilation flow path is directed to the PPVS.

The only normally occupied area with CVCS leakage (Corridor - Room 79) h&s potential radioactive airborne concentrations that are a very small fraction of the MPC,

    • Based on the "American National Standard Radioactive Source Term for Normal Operation of Light Water Reactors" (ANSI /ANS-18.1-1-1984), reactor coolant concentrations for Xe-133 are a factor of 7 less than the "American National Standard Source Term Specification" (ANS-18.1, ANSI N237-1976). If this factor is applied to the reported Xe-133 concentration, the total building MPC would be significantly reduced.
