ENCLOSURE 1 TMI UNIT 1 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION TECHNICAL SPECIFICATION CHANGE REQUEST No. 326 ELIMINATION OF CONTAINMENT EQUIPMENT HATCH CLOSURE DURING REFUELING 5928-05-20124 Page 1 of 3

1. NRC Question The FHA radiological consequence analysis for Amendment No. 236 uses X/Q values that were derived assuming a diffuse source release from the reactor building; i.e., the activity being released is assumed to be homogeneously distributed throughout the reactor building and leak over the entire reactor building surface. In reality, the releases are likely to occur through the unit vent or through an open personnel, equipment, and/or emergency hatch. Please confirm that the diffuse source control room X/Q values used in the Amendment No. 236 dose assessment bound the atmospheric dispersion characteristics for releases from the unit vent, personnel hatch, equipment hatch, and emergency air lock.

Response

As stated above, the dose previously calculated for the Fuel Handling Accident Inside Containment (FHAIC) radiological consequence analysis for Amendment No. 236 used a X/Q value that was derived assuming a diffuse source release from the reactor building; i.e., the activity being released is assumed to be homogeneously distributed throughout the reactor building and leak over the plane of the reactor building surface perpendicular to the control room air intake tunnel. This previously calculated diffuse X/Q value was 3.40E-04 sec/m 3 for a 0-2 hour release.

In order to confirm that the X/Q value selected is the bounding value, it was decided that a X/Q for the equipment hatch, unit vent, personnel air lock, and emergency air lock (positioned within the equipment hatch) would be re-calculated for the control room intake using ARCON96 and the guidance provided in Regulatory Guide 1.194. Please refer to the enclosed calculation (Enclosure 2) for additional details. Enclosure 3 provides an electronic disk containing the ARCON96 files as well as the same four years of meteorological data (1992, 1993, 1995,1996) used to develop the existing licensing basis X/Q values previously reviewed and approved in TMI-1 Amendment Nos. 210 and 215, dated April 15, 1999 and August 24,1999, respectively. This meteorological data was used in the calculation provided in Enclosure 2 to develop the revised X/Q values described above. As discussed in Enclosure 2, upper level wind data is not used in the new X/Q determinations. The associated upper level wind speed instrument is not required by TMI Unit 1 Technical Specifications nor is it necessary for this analysis since only ground level release X/Q values are being determined. Consistent with the previous license amendment request supporting TMI-1 Amendment No. 210, referenced above, since less than 90% of the 1994 TMI meteorological data was recovered, this year is excluded.

These new X/Q values are summarized below:

Location 0-2 Hours X/Q (sec/m 3)

Unit Vent: 5.34E-04 Personnel Air Lock: 2.68E-04 Equipment Hatch: 4.51 E-04 Emergency Air Lock: 4.47E-04 Since releases can occur through the unit vent or through open personnel, equipment, and/or emergency hatch, the highest X/Q (5.34E-04 sec/M 3 corresponding to the unit vent) is used to develop the revised control room dose consequence for the FHAIC.

5928-05-20124 Page 2 of 3 Note that the filter that is available and aligned on this pathway is still not being credited in the dose analysis.

Regarding the calculated dose to control room operators, the X/Q value is a direct multiplier in the dose equation. Therefore, since the fuel handling accident occurs over a two-hour period, the X/Q ratio (new / previous) for the 0 to 2-hour release period can be applied as a direct multiplier to the originally calculated control room dose as follows to obtain the new maximum calculated dose:

0.655 Rem TEDE x (5.34E-04 / 3.40E-04) = 1.028 Rem TEDE Where:

0.655 Rem TEDE = originally calculated/submitted/approved dose 5.34E-04 = highest new calculated X/Q value (sec/m 3 ) the unit vent 3.40E-04 = previously calculated diffuse source X/Q value (sec/M 3 )

The revised FHAIC calculated control room operator dose of 1.028 Rem TEDE, based on using the bounding X/Q value described above, remains well below the regulatory criteria of 5 Rem TEDE specified in 10 CFR 50.67 and GDC-19. The previously analyzed Exclusion Area Boundary and Low Population Zone dose consequences are not impacted by this change.

Note that this control room dose value will be further revised as a result of changes being made to the dose analysis model assumptions and parameters in response to additional NRC review questions. These changes have no impact on the above bounding calculation for the X/Q value. The final calculated dose consequences for the FHAIC are being submitted separately and are expected to remain well below the regulatory criteria.

2. NRC Question The FHA radiological consequence analysis for Amendment No. 236 uses X/Q values that were derived assuming all infiltration into the control room (both filtered and unfiltered) occurs through the control room yard air intake. Using the results of the tracer gas testing performed on the TMI-1 control room envelope, please confirm that there are no potential unfiltered inleakage pathways during the control room isolation mode that could result in X/Q values that are higher than the control room yard air intake X/Q values.

Response

The tracer gas testing report confirms that there are no specifically identified potential unfiltered inleakage pathways in the control room isolation mode that could result in X/Q values that are higher than that for the control room yard air intake. This is further demonstrated by the fact that differential pressure readings between all areas within the control room (CR) envelope and outside areas were shown to be positive. Positive pressure in the CR with respect to outside areas precludes inleakage through the boundary walls. This implies that the more credible source of inleakage would be through the air intake tunnel as currently described. The maximum inleakage as measured by the tracer gas test was during operation of the "A" train at 233 +/-129 cfm 5928-05-20124 Page 3 of 3 (189 +/- 103 cfm for the "B" train). Additionally, the maximum assumed unfiltered inleakage value used in the TMI-1 design basis calculations is 1,000 cfm, which provides significant margin compared to the maximum measured values. The personnel air lock, although located within the Intermediate Building, is in a location close to the Control Building. It is unlikely that leakage through the personnel air lock would be directed towards the Control Building that could contribute to unfiltered inleakage through the CR boundary walls. This is partially due to the positive pressure in the Control Building as well as the fact that leakage from the air lock would be into the Intermediate Building and/or Turbine Building. The Intermediate Building normal exhaust pathway is through the unit vent. The Turbine Building exhaust pathway would be farther away and more favorable. For conservatism, the X/Q for the personnel air lock was based on its location without credit for any release-containing structures. The more credible inleakage path into the CR is through the air intake tunnel. Therefore, use of the highest calculated X/Q value (unit vent, personnel air lock, equipment hatch, or emergency air lock), as described in response to Question No. 1 above, ensures that the maximum credible calculated dose is determined. Based on the above, it is concluded that other potential pathways do not represent credible unfiltered inleakage pathways to the CR during CR isolation mode of operation.

I CALCULATION NO. C-1101-826-E410-030 I REV. NO.0 _ PAGE 4 of 9 1 1.0 PURPOSE This calculation, C-1 101-826-E410-030, Rev. 0, presents new atmospheric relative concentration (X/Q) values for Alternative Source Term (AST) accident evaluations for the Three Mile Island Station as additions and changes to those provided in Reference 9. The purpose of this calculation is to determine the Yard Intake relative concentration values (X/Q, in sec/M3 ) resulting from certain postulated accidental radiological release locations that may be different from those in Reference 9. The values resulting from this calculation can be used as input for the determination of radiological doses using the Alternative Source Terms (AST) per Regulatory Guide (RG) 1.183 (Reference 1) for these new release locations.

The X/Q values resulting at the Yard Intake are calculated using the NRC-sponsored computer code ARCON96 (Reference 2) consistent with the guidance in RG 1.194 (Reference 3). This analysis is presented in Section 2.0 below.

2.0 ARCON96 ANALYSIS OF YARD INTAKE X/Q FOR NEW RELEASE LOCATIONS 2.1 Identification of Computer Programs/Method of Analysis ARCON96 is a commercial software package designated by Washington Group International as NU-830, an "active" program applicable to nuclear safety related analyses as well as non-safety related studies and evaluations. Its use is principally control room habitability assessments. The NU-830 code has been verified for 0-2 hour, 2-8 hour, and 8-24 hour centerline and sector X/Q averages and the 95% maximum X/Q. This verification is in accordance with Revision 4 of the Washington Group International Nuclear Engineering Standard for Computer Software Control, NEP-09. Revision 0 of NU-830 was verified for ground-level and zero exit velocity uncapped vents, and Revision 1 was verified for zero exit velocity stack releases.

ARCON96 Program Description [excerpted from NUREG/CR-6331 Rev. 1 (Reference 2)]

ARCON96 is a straight line Gaussian dispersion model used in control room habitability assessments for estimating dispersion in the vicinity of buildings to calculate relative concentrations at control room air intakes that would be exceeded no more than five percent of the time. The basic diffusion model implemented in the ARCON96 code is a straight-line Gaussian model that assumes the release rate is constant for the entire period of release. This assumption is made to permit evaluation of potential effects of accidental releases without having to specify a complete release sequence. Ambient atmospheric conditions measured in accordance with RG 1.23 (Reference 4) are input to ARCON96 by way of a sequential hour-by-hour meteorological database of jointly measured wind speed, wind direction, and Pasquill stability class, as derived from the vertical temperature difference recorded at representative elevations (i.e., tower levels).

ARCON96 permits evaluation of ground-level, vent, and elevated releases. Building wake effects are considered in the evaluation of relative concentrations from ground-level and vent releases as a function of the ratio between the effluent vertical velocity and the release-height wind speed, using the same procedure used in the NRC XOQDOQ code (Reference 5).

Diffusion coefficients used in ARCON96 have three components. The first component is the diffusion coefficient used in other NRC models, for example XOQDOQ, and PAVAN. The other two components

CALCULATIONNO. C-1101-826-E410-030 I REV. NO.0 l PAGE 5 of 9 are corrections to account for enhanced dispersion under low wind speed conditions and in building wakes.

Derivations of the low wind speed and building wake corrections are described by Ramsdell and Fosmire (Reference 6). Parameter values for the correction factors are based on analysis of diffusion data collected in various building wake diffusion experiments (Reference 6). The experiments were conducted under a wide range of meteorological conditions. However, a large number of experiments were conducted during low wind speeds, when wake effects are minimal. The wake correction model included in ARCON96 treats diffusion under these conditions much better than previous models. Thus, the diffusion coefficients in ARCON96 account for both low-wind speed meander and wake effects.

ARCON96 calculates relative concentrations using hourly meteorological data. It then combines the hourly averages to estimate concentrations for periods ranging in duration from 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to 30 days. Wind direction is considered as the averages are formed. As a result, the averages account for persistence in both diffusion conditions and wind direction. Cumulative frequency distributions are prepared from the average relative concentrations. Relative concentrations that are exceeded no more than five percent of the time (95th percentile relative concentrations) are determined from the cumulative frequency distributions for each averaging period. Finally, the relative concentrations for five standard averaging periods used in control room habitability assessments are calculated from the 95th percentile relative concentrations.

2.2 Assumptions The following dimensions were assumed based on minimizing distances from the release to the intake and verified as conservative during a site walkdown on May 24, 2005:

• Unit Vent release height 6 ft above the top of the Reactor Building.

• Personnel Hatch release at the top of a 6 ft doorway positioned on the platform shown in Attachment A.

In addition, the Equipment Hatch and Emergency Airlock release heights were set equal to the intake height.

2.3 Inputs 2.3.1 Meteorological Data The Three Mile Island meteorological tower data for the four years 1992, 1993, 1995 and 1996, as supplied by Exelon (Reference 7), were applied in the ARCON96 modeling analyses. Wind measurements were taken at tower elevations 100 ft and 150 ft.

Executing ARCON96 requires the meteorological input file to contain two (2) wind levels (lower and upper), however, since the tower data are validated at the 100 ft level only, the 100 ft wind data were substituted for the 150 ft wind data, resulting in an ARCON96 meteorological database with two identical levels of wind data to represent the lower and upper level required input.

Attachment B includes the four yearly wind rose diagrams based on the 100 ft meteorological tower wind data and Attachment C contains the joint wind direction, wind speed, and stability class distribution tables for the same data.

1 CALCULATION NO. C-I 101-826-E410-030 l REV. NO. 0 l PAGE 6 of 9 2.3.2 Yard Intake Scenarios The release points identified for consideration at Three Mile Island are the Unit Vent, Personnel Hatch, Equipment Hatch, and Emergency Airlock. The locations of these release points are shown in Attachment A (Reference 8).

All release points were modeled in ARCON96 as ground-level releases. Aerodynamic building plume downwash effects are present for ground-level releases; therefore, in accordance with RG 1.194, the building area perpendicular to the wind direction is utilized. For all scenarios, the Containment Building area of 2127 m2 was utilized (Reference 9).

The center of the Yard Intake is located 18 ft (5.49 m) above grade as seen in Attachment D (Reference 10), and is identified with respect to the release points in Attachment E (Reference 11).

ARCON96 requires a horizontal source-receptor distance to be input, which is defined in RG 1.194 Section 3.4 as "the shortest horizontal distance between the release point and the intake". However, for releases in building complexes, a "taut string length" can be utilized as justifiable. For the Personnel Hatch this "taut string length" (calculation shown in Attachment F) was utilized to account for the intervening Fuel Handling Building. Per a Washington Group International phone conversation with Mr. Steve Lavie of NRC on May 17, 2004, when the "taut string length" is utilized, the intake and release height should be set equal to each other so as not to also take undue advantage of the slant distance that ARCON96 calculates.

Therefore, for the personnel hatch, the intake height was set equal to the release height, of 3.5 m.

The releases for the Yard Intake modeling scenarios are each treated as a point source, and are conservatively assumed to have a zero (0) vertical velocity, exhaust flow and stack radius. The ARCON96 input parameter values were set in accordance with RG 1.194, Table A-2 (e.g. surface roughness length = 0.2 m; wind direction window = 90 degrees, 45 degree on either side of line of sight from source to receptor; minimum wind speed = 0.5 m/s; and averaging sector width constant = 4.3).

A summary of ARCON96 input parameters and certain output meteorological data statistics is shown below in Table 2-1.
