-CE
-2076L Page 10 of 18 INSERT B for " Background":
The post accident function of the Main Steam Stop Valves (MSSVs) is to be manually closed in order to provide a reduction ofpost accident dose associated with the main steam line leakage path.. With the stop valves in a closed position, mitigation of the off-site and Control Room dose is achieved by taking credit for the deposition of particulate forms of released fission products (aerosols) on the inner walls of the four main steam lines. This removal process is based on a " plug flow" model for the Main Steam Isolation Valve (MSIV) leakage with relatively even, slow cooldown of the insulated main steam lines. The closed position of the MSSV supports the plug flow model by providing isolation of the spacejust upstream of the MSSV from external convection which could i
originate from the downstream nonsafety side of the MSSV. Therefore, the MSSVs are
~
required to move to a closed position, but are not required or credited with any tightness againstleakage. The operator response to provide the manually initiated closure for the MSSVs is 20 minutes post-LOCA (Ref.1). Failure of all four MSSVs to close is taken as a single active failure based on a single operator error or on a loss of divisional power.
This failure is not coincident with a single MSIV failure to close.
INSERT C for " Applicable Safety Analysis":
The applicable safety analyses are the off-site and Control Room radiological dose calculations. The MSIVs in the main steam lines are required to close when a design basis accident (DBA) occurs. Failure to close an MSIV would affect the retention of the fission product aerosols in that main steam line (and therefore the fission product release to the environment), unless a holdup volume could be established downstream of the closed MSIV in that line,i.e., using the Main Steam Stop Valve. In determining the most limiting single failure case that would result in the highest (most conservative) calculated off-site doses, two cases were examined.
- 1. The single MSIV failure to close case results in less off-site and Control Room dose (than failure of all four MSSVs to close) because of credit for particulate deposition in the downstream volumes out to the closed MSSVs.
- 2. Failure of all four Main Steam Stop Valves (MSSVs) to close is taken as a single active failure based on a single operator error or on a loss of divisional power, and results in the most limiting dose consequences. This failure is not coincident with a single MSIV failure to close. This limiting case assumes that main steam line leakage is attenuated in the main steam line from the reactor vessel out to the outboard MSIV.
Although this most limiting analysis case assumed a failure to close the Main Steam Stop Valves, retention of OPERABILITY requirements on these valves is appropriate to ensure the single failure analysis associated with the LOCA off-site and Control Room dose reanalysis remains valid. The Main Steam Stop Valves meet Criterion 3 of1OCFR50.36 (c)(2)(ii).

INSERT D for"LCO":
'Ihe four MSSVs are part of the mitigation strategy for off-site and Control Room dose consequences. Failure of all four MSSVs to close is taken as a single active failure based on a single operator error or on a loss of divisional power, and results in the most limiting 1
dose consequences. Although this most limiting analysis case assumed a failure to close the Main Steam Stop Valves, retention of OPERABILITY requirements on these valves is appropriate to ensure the single failure analysis associated with the LOCA off-site and l
Control Room dose reanalysis remains valid.
INSERT E The ACTIONS are modified by a Note allowing separate condition entry for each penetration flow path because an inoperable MSSV in a main steam line does not affect the ability to provide a holdup volume in the affected line (between the MSIVs) or in the i
other lines (between the MSIVs and/or the MSSVs). The Required Actions provide appropriate compensatory actions for each inoperable MSSV. Complying with the Required Actions may allow for continued operation, and subsequent inoperable MSSVs are governed by subsequent Condition entry and application of associated Required Actions.
INSERT F for Action "A.1":
1 The purpose of closing two valves in a main steam line is based on the characteristics of j
the revised design basis accident source term (i.e., predominantly aerosol), and provides a holdup volume within the main steam line for deposition of the aerosol on the inner walls of l
the main steam line. If an MSSV is " inoperable", but closed, credit can be taken for it in j
meeting the ACTION. Leak tightness of the MSSVs is not necessary to ensure the assumptions of the dose calculation methodology are met for the main steam lines, since leakage flow characteristics used in the analyses are affected only by the turbulence caused by an open ended pipe (i.e., the Main Steam Stop Valves fail to close),

The only necessary surveillance requirement is one to ensure the valves will stroke closed
, on a manual demand by the operators. Leak test requirements are not necessary to ensure the assumptions of the dose calculation methodology are met for the main steam lines, since leakage flow characteristics used in the analyses are affected only by the turbulence caused by an open ended pipe (i.e., the Main Steam Stop Valves fail to close). The 18 month frequency is based on the need to perform this Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the Surveillance were performed with the mactor at power.

BASES l
BACKGROUND The Combustible Gas Mixing System ensures a uniformly mixed post accident containment atmosphere, thereby minimizing the 30tential for local hydrogen burns due to a pocket of lydrogen above the flammable concentration.
The Combustible Gas Mixing System is an Engineered Safety Feature and is designed to operate following a loss of coolant accident (LOCA) in post accident environments without loss of function.
There are two redundant and I
independent combustible gas mixing subsystems, each l
consisting of a compressor and associated valves, controls.
and piping.
Each combustible ga<, raixing subsystem is sized to pump 500 scfm.
Each subsy: tam is powered from a separate emergency power supply. Since each combustible gas mixing subsystem can provide 100% of the mixing requirements. the system will provide its design function with a worst case singl.e active failure.
Following a LOCA, the drywell is immediately pressurized due to the release of steam into the drywell environment.
This l
pressure is relieved by the lowering of the water level l
witk in the weir wall, clearing the horizontal vents and allowing the mixture of steam and noncondensibles to flow into the primary containment through the sup3ression pool, removing much of the heat from the steam.
T1e remaining steam in the drywell begins to condense.
As steam flow from the reactor pressure vessel ceases. the drywell pressure falls rapidly. The combustible gas mixing compressors are manually started prior to the drywell hydrogen concentration exceeding 3.0 v/o. The compressors force air from the primary containment into the drywell.
Drywell pressure i
increases until the water level between the weir wall and the drywell is forced down to the horizontal pool vents forcing dryvnll atmosphere back into containment and mixing with containment atmosphere to dilute the hydrogen.
While combustible gas mixing continues following the LOCA, hydrogen cons nues to be produced.
Eventually, the 4.0 v/o limit is again approached and the primary containment g g.T. g e hydrogen recombiners are manually placed in operation.

INSERT "I" The containment spray is credited with removal ofairbome radionuclides. Post-LOCA operation of the mixing compressors also provides a transport of air between containment and the drywell.
Therefore, post-LOCA dose is reduced with mixing compressor operation.

.m PY-CELTRR-2076L Page 23 of167 3.0 FIELD PROGRAM DESCRIPTION The technical approach for the tracer study field program was as follows:
Atmospheric tracer tests v:ould be conducted within the Perry Build-o ing Complex under selected meteorological conditions in order to measure actual atmospheric dispersion (Chi /Q).
The selected meteorological conditions would be based on the con-o trolling conditions indicated by the Murphy and Campe (1974) l l
methodology.
o Other meteorological conditions would be sampled to determine if other conditions were associated with the highest Chi /Qs.
l o
One-hour averages of Chi /Q would be measured for continuous releases from the reactor building to the air intake of the Control Complex.
The reactor building source would be represented by two release o
points:
- 1) stack vent (top), ar.d 2) the lee of each reactor build-ing 1 m above roof level and closest to the air intake.
Two tracers would be used simultaneously at two different release o
locations to permit obtaining two Chi /Qs per test hour.
Some tests would be conducted sequentially (with no time gap) in o
order to provide information on any possible buildup within the building wake.
i To provide qualitative information on the general dispersion pat-o terns within the Building Complex, additional Chi /Qs would be mea-sured at a limited number of receptor points. in the general vicin-ity of the air intake.
Smoke releases would also be made.
3-1 NUS CORPORATION l
PY-CEUNRR-2076L Page 24 of167 I
In the three following subsections, the various aspects of the field program are described:
o Meteorological measurements o
Tracer release and measurements o
Smoke releases 3.1 Meteorological Measurements There are parts to this section that describe meteorological measurements for the study within the Building Complex at Perry:
Meteorological Tower Temporary Towers Operating Procedures Data Processing Pictures of various aspect:1 of meteorological measurements are presented in Appendix 0.
3.1.1 Meteorological Tower The location of the permanent Perry Meteorological Tower (PMT) is shown in Figure 3-1.
This 60-m tower is located approximately 6,000 f t inland at an elevation of approximately 645 ft MSL.
The immediate terrain is flat with grasses, small shrubs and small trees.
i The meteorological tower includes a Main System and independent Backup System.
The meteorological variables measured with each are described in Table 3-1.
Specifications, which meet the intent of Regulatory Guide 1.23, for the meteorological equipment are reported in Table 3-2.
Each inde-pendent system includes a computer (Meteorological Data Processing System-MDPS) that determines fifteen-minute and hourly values for each variable.
3-2 NUS COAPORATION a
PY-CE1MRR-2076L i
Page 25 of 167 Included in the determination is a realtime validation process (Mitchell et al, 1985) that utilizes redundant collocated sensors.
The values determined by the MDPS are available on hard copy as well as upon demand via tele-phone. A complete description is available in the ninth annual report (Timbre, 1985).
3.1.2 Temporary Towers For the tracer study, two temporary meteorological towers were installed:
Upwind Temporary Tower (UTT) - This 10-m tower was located just o
east of the cooling towers within the protected security area.
i Control Complex Roof (CCR) - This 10-m tower was centered on the o
roof of the Control Complex about midway between the containments and air intakes (west face of the Control Complex).
The PMT was used as the benchmar.k key indicator, since all historical data are based on this tower that was described in Section 3.1.1.
These other two locations were used to supplement the PMT during the tracer tests.
The locations of the three towers are depicted in Figure 3-1.
The variables measured at each for the tracer study are summarized in Table 3-3.
The two temporary monitoring locations, UTT and CCR, had a different moni-toring system than the permanent PMT (described in Section 2.2).

and CCR systems were Climatronics units with Rustrak recorders. The performance specifications for UTT and CCR systems are summarized in Table 3-4 The PMT is routinely calibrated and maintained by The Cleveland Electric Illuminating Company in accordance with approved procedures.
The UTT and CCR instrumentation was installed and calibrated by NUS just prior to the field study. A post-test calibration was performed following the field program, just before removal.

The NUS Test Director and staff followed procedures established for the Perry tracer study.
Each day the Test Director monitored the current and forecast meteorology for events of desirable meteorological conditions:
1 1.
Controlling Conditions--related to the Murphy & Campe evaluation (see Section 1.2):
+ Wind Direction N through SE
+ Wind speed less than or equal to 1 m/s
+ Stability Class F, based on delta T (60-10m) 2.
Meteorology of Interest--generally restrictive dispersion:
+ Wind Direction N through SE t
+ Wind Speed less than or equal to 3 m/s
+ Stability Class E, F, or G 3.
More Mixed--less restrictive dispersion:
+ Wind Direction N through SE
+ Wind Speed greater than 3 to 7 m/s
+ Stability Class C, D, E, F, or G A review of historical data at Perry had indicated that the desirable mete-orology most routinely occurred around sunset. Therefore, a tentative start to testing was scheduled about 1800 EST. Onsite data (Perry Meteorological Tower) and National Weather Service information were used to decide whether or not to prepare for testing or to stand by.
NUS and Tracer Technologies staff were advised of the decision to proceed.
Once the decision to test (1-hour duration) was made, realtime conditions at l
1 all three meteorological towers were monitored at the CCR (from the UTT by I
voice; from the PMT by portable terminal).
From hour to hour a decision was made whether or not to proceed with an additional hour of testing.

t testing was in progress, it was continued (consecutive hours) until mete-orological conditions were no longer favorable.
As the testing proceeded, the annotated forms were filled out, and chart records to identify locations, timing, approximate conditions, etc., were marked. At the end of the test day, strip charts were removed from the UTT and CCR. Digital data from the PMT was obtained by telephone interro-gation.
The charts and digital data were subsequently logged in for processing, l

5.1.4 Data Processing 1
The processing of meteorological data was performed in accordance with writ-ten procedures. The analog charts and digital records were logged in, reviewed, and reduced to one-hour averages for the one-hour periods desig-nated as test periods.
Test hours are periods during which desirable mete-orology was expected to occur and tracer and/or smoke releases were made.
The one-hour values were read directly (or calculated from 15-min values) for each variable indicated in Table 3-3.
The meteorological values by test were then placed in files for use in the analysis.
3.2 Tracer Release and Measurements Gaseous tracers were used to measure the dispersion between the containments j
and the intakes to the Control Complex.

Pictures of various aspects of tracer measurements are presented in Appen-i dix D.
3.2.1 Tracer Materials and Equipment This section describes the tracer and related equipment and explains what calibration and materials were implemented to use the equipment.
3.2.1.1 Gases 4
Two gases were used to quantitatively describe the atmospheric dispersion during the tests:
o Sulfur hexafluoride (SF )
6 Bromochlorodifluoromethane (BCF), Halon l'211 o
Both of these non-toxic gases have been previously used in tracer studies.
The characteristics of SF6 and BCF are summarized in Table 3-5.
3.2.1.2 Release Equipment The tracer release system consisted of four main parts:
the tracer gas cylinder, regulator, flow control valve, and a mass flowmeter / recorder.
The tracer existed as a liquid under pressure with a vapor pressure of between 60 and 150 pounds per square inch gauge (psig), depending on temperature.
The cylinder regulator reduced this pressure to approximately 5 psig as vaporized tracer was bled off for delivery to the flow control valve.
The tracer gases were expected to dilute and reach ambient temperature within a short distance from release, the order of one meter, and achieve neutral buoyancy within this distance. A Hastings mass flowmeter allowed the accurate monitoring of the mass flow of the release at varying ambient temperature and pressure.
The output of this flowmeter was recorded on a stripchart to provide a hardcopy record of the release rate.
3-6 NUS CORPOAATION
.~
Attacnment 3 PY-CEl/NRR-2076L Page 29 of167 Prior to use in the field, the proper calibration of the mass flowmeter was verified gravimetrically. A cylinder of tracer gas was weighed prior to connection to the flowmeter.
This cylinder was then used as a release i
source through the flowmeter system at or near the proposed release rate.
The flow rate was continuously recorded, and tracer was released for a period of time estimated to yield at least a 10 percent change in cylinder weight. The cylinder was re-weighed, and the loss of tracer compared to the recorded release rate multiplied by the release time.
The mass flowmeter calibration was re-checked on return to the laboratory.
Because this instrument is very rugged and reliable, the expected variation in flow rate l
was generally the order of one to two percent.
As the flowrate was moni-l tored by an analog trace during the tests, the rate could be adjusted, as
{
1 necessary.
3.2.1.3 Samplers Automated sample collection was accomplished by an electronically-operated pump-and-solenoid-valve switching system.
Each sampler was capable of col-lecting four one-hour samples and required operator intervention only every four hours to change sample bags.
The complete sampling assembly consisted of a pump, four solenoid valves, electronic control circuit board, delay timer, and battery.
As it was dif-ficult to obtain battery-powered pumps which will operate reliably at very low (less than 20 ml/ min) flow rates, the pumps were operated at 15 percent duty cycle.
During sampler operation, the valves opened for approximately 2 seconds of every 11 seconds of operation, and the pumps operated contin-uously.
Electronic timing' circuitry controlled the opening, closing, and selecting of the appropriate solenoid valve for the particular hour of operation. A one-hour delay timer was included in each sampler to allow deployment of the sampler prior to the actual onset of sampling, thus allowing one person to place several samplers.
Sampling bags were attached to four Tygon tubes of the sampling assembly.
The sampling bags had a nipple nozzle valve and were put in place on the l
tubes by pressure fit.
The bags had a volume capacity of approximately four 3-7 NUS COAPORATION

The nozzle on the bag included a valve that could be screwed chut when the bag was removed.
t l
l All samplers were checked prior to departure to the field. The initial test required that four bags be attached to the sampling ports and the samplers be placed in operation.
All were checked for proper flow rate, cycle time, delay operation, and reliability.
Any units failing this test were removed from service and repaired. All units were then checked further with a l
calibrated flowmeter.
This test gcnerally isolated marginal pumps or l

3.2.1.4 Analysis Equipment l

\\
All field samples were analyzed by electron capture gas chromatography.
The chromatograph consisted of a sample valve containing an integral 1-ml sample volume for repeatability.
When this sample volume was loaded and the chromatograph switched to the RUN position, the contents'of the sample were flushed into a heated separation column by a flow of nitrogen carrier gas.
The separation column consisted of a four-foot length of 1/4" tubing, which was packed with a SA molecular sieve.
In passing through the column, each tracer separated from the other components of air and emerged as distinct entities. Then the effluent of the column entered the electron capture detector.
The response of the detector was amplified and recorded on a stripchart recorder for each entity.
The chromatographs were thoroughly checked prior to shipment to the field.
The response of each channel of the chromatograph was individually determined at multiple points with calibration gas of different dilutions.
The calibration gas contained known quantities of SFs and BCF that had been
{
determined by gas coulometry. This process determined the linear response characteristic of each channel.
The stripchart recorder was calibrated with a certified voltmeter prior to shipment.
In the field, single-point calibrations were used.

i has shown that this method is accurate to within five to ten percent.
Prior 4
to and after use and every hour during use, the standard calibration gas was used to measure the chromatograph response. This provided deta to normalize the magnitude of the response of the chromatograph to the returned air i
samples.
3.2.2 Source and Receptor Locations I
The layout of the plant was described in Section 2.
The source and receptor I
locations within the Building Complex were selected to represent the atmos-pheric dispersion between the reactor buildings and the air intakes to the Control Complex.
The sources and receptors are listed in Table 3-6, and
}
their locations within the Building Complex are shown in Figures 3-2 and 3-3.
In addition, there are some photographs in Appendix D.
I
{
For all practical purposes, releases from either Unit 1 or 2 were assumed to i
be equivalent.
So, for a given test, the sources were either Source 1 and 3 or Source 2 and 3.
Each of the two sources would use a different tracer.
Source 1 or 2 in the lee of the containment at roof level was expected to 3
represent a leak that would get the least dispersion.
Source 3 represented f
the other potential major source to the air pathway to the intakes.
The primary receptor locations were at the air intakes (#2 and #4) to the Control Complex.
The samplers were hoisted by pulley to just underneath the intakes (the intakes face downward as they protrude from the west face of i
the Control Complex). The additional receptor locations outside the building were positioned to better describe the conditions around the in-takes and to quantitatively learn more about the trajectory of the tracers.
A control location was established upwind at the UTT.
3.2.3 Operating Procedures When the NUS Test Director identified a "go" for testing (see Section 3.1.3), the Tracer Technologies staf f took pre-test grab samples of back-3-9 NUS CORPORATION PY-CEl/NRR.2076L Page 32 of 167 l

ground conditions (of the two tracers) outside and inside the Control Complex.
l 3.2.3.1 Release Equipment About 5 to 15 minutes prior to the start, the tracer release equipment was sited and started (for warmup, adjustment, and confidence that the gases had
{
~
time to get to the outside receptors before the start of sampling).
To begin the flow of tracer, the flow control valve was closed and the cylinder shutoff valve slowly opened until the desired flow rate was indicated.
Due i
to the response time of the mass flow meter, it was usually necessary to make readjustment during the first 5 to 30 minutes for the BCF.
The release rates were set for nominally 0.1 pound per hour.
During the testing the flow rate was checked one or more times per hour.
The SF6 was released at location #3 at the vent stack (lee top edge or 1 m below the top). The BCF was released at location #1 or #2 in the lee of the containment for Unit 1 or 2, respectively.
The positioning at #1 or #2 was based on consultation with the Test Director and on anticipated meteorology.
3.2.3.2 Samplers l
Samplers were set to start collection at the prescribed time.
Prior to the beginning of sampling, each of the four sample ports was fitted with a sample bag. When the sampler was actually deployed, the technician set the delay timer for the appropriate time delay and switched the unit on.
I i
If a test day was to last more than four hours, the technician would visit the sampler after two or three hours and remove the filled bags, replacing them with fresh bags for the subsequent hours. All bags were labeled with the date, time, location, sampler number, and technician name for data tracking. During the testing, each sampler was checked one or more times j
per hour for proper operation and bag labelling.

1 As sample bags were returned to the analysis laboratory outside of the Building Complex, their location, sampler number, and date/ time information were noted. As each bag was analyzed with the chromatograph, a vigilance for possible malfunctions or tracer contamination was maintained.
As the samples were analyzed in the gas chromatograph, the tracer magnitude sample of the tracer peaks were determined from the chromatogram.
Magni-tudes were logged by time and location in order to confirm proper release rates and to detect potential sampler malfunctions or procedural problems.
Analyzed bags were flushed with nitrogen and given a new label--in prepara-tion for redeployment and reuse.
3.2.4 Data Processing All chromatograms were read:
the magnitude of the tracer sample trace was recorded. The chromatograms were independently read a second time. The i
larger of the independent readings was used in the case of small differences; any large differences were resolved.
The chromatogram peak heights (mm) from the sample were compared to those from the hourly span gas The measured peak height of the air sample was multiplied by the run.
concentration of the span gas divided by the average span peak height.
This yielded a tracer concentration (parts per trillion) for the sample that was adjusted for drif t, if any, in the chromatograr$.
l The source rate 0 (g/ min), was based on readings from the mass flowmeter for the respective tracer gas during each test and the purity of the source gas.
From the calibration of the mass flowmeter, the voltage output was related to a particular flow rate (g/ min) for that tracer.
The normalized concentration, Chi /Q, was determined by dividing the sample concentration (ppt) by the source rate (g/ min) of the tracer.
The result was multiplied by the conversion factor to yield Chi /0 in units of seconds
['
per cubic meter.
The conversion factor for SF was 3.72E-7; for BCF, 6

The f actor accounts for the molecular weight of the tracer gas in 3
converting the volumetric concentration (ppt) to a mass concentration (g/m )
normalized by the source rate (mass of tracer / time).
l 3.3 Smoke Releases Smoke releases were used to cualitatively evaluate atmospheric dispersion conditions.
Smoke was generated by using smoke candles.
The Five-Minute Smoke Bomb, manufactured by Supervisor Signal Company, was used to generate approximately 100,000 cubic feet of smoke. The light colored smoke that was produced by these bombs contained a large percentage of moisture rather than solids. Usually two or three were set off at once in a metal five gallon pail.
Smoke was released one or more times per test hour, generally from two or more locations. The two locations corresponded to the tracer locations near the top of the stack (#3) and in the lee of Unit 1 or 2 (#1 or #2, respec-tively).
Sometimes an additional smoke release was made from the lee of the other containment.
The Test Director made observation of the movement of the smoke.
Immediate use of the movement was to confirm / adjust the choice of the containment (#1 or #2) for tracer release most likely to cause the higher concentrations to l
the air intakes on the west face of the Control Complex.
Observations were recorded on forms.
Two visual records of the smoke releases were made.
Since most of the tests were at night, over 10,000 watts of lighting were used on the roof of the Control Complex to illuminate the smoke:
The Test Director used a video camera to make a video tape of the o
releases from the roof of the Control Complex; verbal remarks were recorded on the audio portion of the tape.

Photographs were taken every 30 to 60 seconds during the release 1

l 4.0 FIELD PROGRAM DATA SUMMARIZATION The field program of the tracer study within the Building Complex at Perry 1
was conducted in September 1985.
The setup of equipment was accomplished on l
September 16 and 17.
The measurements were conducted on September 18 through 25.
Equipment takedown was performed on September 26 and 27.
l During the eight days of the field testing, 30 tests were conducted.
In addition to meteorological data, each test involved tracer and/or smoke releases.
The tests occurred at every hour of the day except the period of 0800 to 1200 EST.
The data gathered during the tests are summarized into three groups:
Meteorological Data Tracer Data Smoke Release Data l
i 4.1 Meteorological Data The meteorological data were collected from each of the three towers for all of the 30 test hours:
o PMT - Perry Meteorological Tower o
UTT - Upwind Temporary Tower o
CCR - Control Complex Roof These towers were described in Section 3.
The hourly meteorological data for each test hour are shown in Table 4-1.
Comparative plots of the data are shown in Appendix C.
A wide variety of conditions was experienced, as represented by the PMT.
j Stability classes ranged from A (very unstable) through G (very stable).
Wind speeds ranged from 0.9 to 4.7 m/s. Wind directions from sectors north-northeast (clockwise) through south-southeast were experienced.
I 4-1 l
NUS CORPOAATION l

mwmism a PY-CEl/MRR-2076L Page 49 of 167 i
Table 4-2 summarizes the conditions and activities for each test.
From i
Tables 4-1 and 4-2, Table 4-3 was derived. These tables show that the tests included the range of meteorological conditions which were targeted for the study--except for north and north-north east wind directions.
As shown in Appendix C and Table 4-1, the data collected at one of the temporary towers (UTT or CCR) was not always the same as that observed at the permanent PMT. Most of the differences were attributed to the interfer-ence and turbulence created by the structures near the temporary towers--the cooling towers and trees to the east at the UTT; the cooling towers, con-tainments, and Building Complex itself at the CCR.
Wind fluctuations (sigma) were much larger at these two locations than at the PMT. The larger j
sigmas at the CCR occurred when the tower was in the wake of the contain-ments. Differences in wind direction at the CCR and PMT tended to be associated, too, with the containment wakes.
Although the average wind speeds were fairly close at each location, the hour-by-hour agreement was not.
4.2 Tracer Data Tracer data were collected for 25 of the 30 tests as shown in Table 4-2.
Of these, 24 involved dual tracer release and sampling.
As a result, there were approximately 49 data sets to use in data analysis to determine atmos-pheric dispersion.
The processed tracer data are presented in Tables 4-4 and 4-5 for outside and inside the buildings.
Seemingly zero or very low concentrations were recorded as the known limit of detectability for each tracer and each test.
The lower limit of detectability averaged 3.8E-6 for SF6 and 5.6E-6 s/m 3 for BCF during the study.
4-2 NUS COAPOAATION
PY-CE1/NRR-2076L Page 50 of 167 The outside values in Table 4-4 represent the data set processed from the complete tracer data listings presented in Appendix A.
There were two samples ("A" and "B") for each outside location.
Experience indicated that these typically agree (for collocated samplers) within 15 percent.
And analysis indicated an average agreement near zero and a standard deviation of less than 15 percent. For any location with a difference of less than 15 percent, the "A" value was used in the data set for analysis.
If, how-l ever, the difference was greater than 15 percent, then the higher value of the two was used in the data set for analysis (Table 4-4).
For situations in which one sample was missing, the available value was used unless suspect for some other reason.
The background location (#6 at the UTT) generally had near-zero concentra-tions--that expected for these not-naturally-occurring tracers. However, in several instances where the tubes to the samplers had not been adequately purged, some absorbed BCF tracer from a previous exposure contaminated the sample.
In the future, procedures would be modified to preclude this con-tami nation.
4.3 Smoke Release Data Smoke releases and photography were accomplished for all 30 tests, as shown in Table 4-2.
From one to four releases were made during each test.
Observation notes were taken during each test, as were pictures of the smoke. Still pictures were taken with film and camera from the roof of the Unit 1 Turbine Building, plant north of the Control Complex.
Video tape with verbal remarks was made from the roof of the Control Complex.
Selected pictures of the release are presented in Appendix E.
Each media offered advantages. The photographs from the Turbine Building provided a view predominantly from the side of the direction of plume travel.
The 4-3 NUS COAPOAATION
.---2 PY-CEl/NRR-2076L Pgc 51 of l67 video offered longitudinal views and afforded the opportunity to more directly follow plume phenomenon.
Stills of selected video sequences were made by photographing a " freeze" on a video monitor.
One predominant phenomenon was for releases in the lee of Unit 1 or 2 to move toward the region between the two units.
After mixing in that region, much of the smoke frequently moved up and over the Control Complex, gener-ally toward the west.
Smoke releases from the stack generally moved downwind or upward. On occa-sion during a five-minute release, a puff of relatively dense smoke would move downwind and impact the roof of the Control Complex. Also, occasion-ally, a small portion of the smoke would become entrained in the exhaust coming out of the stack vents.
In general, as smoke moved away from the roof of the Control Complex, the plume would at first appear elevated as the height of building dropped lower onto ground. Then the plume would drop to or closer to the ground at a dis-tance. When the smoke moved out over the Turbine Building to the north, it dropped on the north side of it.
However, if the winds were particularly strong, the Unit 1 or 2 smoke releases would at times move into the canyon between the Control Complex and either of the two Turbine Buildings.
In simplified terms, the material sub-sequently wrapped around the west face of the Control Complex, or else a vortex (horizontal, parallel to the Turbine Building longitudinal axis) developed, the top of which turned away from the top of the Control Complex.
In fact, whenever smoke moved across the roof and roof edge of the Control Complex, with minor exception, it immediately moved upwind in rising air along the face of that edge of the Control Complex.

PY-CE!/NRR-2076L PCge 56 of167 5.0 ANALYSIS As reported in the previous section, 49 sets of source / receptor tracer data were collected over a wide variety of meteorological conditions. These con-ditions included those identified by applying the Murphy and Campe (1974) methodology to calculate Chi /Qs for the intakes to the Perry Control Complex (regarding control room habitability).
Table 5-1 provides statistics about the Chi /Q for each of the outside loca-tions on the Control Complex.
(Values for each test appeared in Table 4-4.)
As described in Section 3.2.2 and Figures 3-2 and 3-3, the five locations are roughly on an arc about 60 m away from the source (Location #1, #2, or
- 3).
Locations #2 and #4 were the two intakes on the west face of the Con-trol Complex, while #1, #3, and #5 were on the roof (SW corner, center pent-house, and NW corner, respectively).
In all of the tests, the maximum Chi /Q observed was 1.9E-4 s/m3 at Loca-tion #5, en the NW corner of the roof of the Control Complex.
However, the maximum Chi /Q at the intakes (#2 and #4) was only 6.8E-5 s/m3 Both of these were significantly lower than the existing Murphy and Campe value of 3.5E-3 s/m3 (see Section 1.2).
That is, the maximum Chi /0 at the intakes was 2 percent of the existing cal-culated estimate. Thus, the tracer data suggest a factor of 50 reduction in the Murphy and Campe value for Perry.
In the remainder of this section, the behavior of observed Chi /Qs from the 4
tracer study is discussed relative to the following:

Relative Concentrations in Consecutive Hours i
5.1 Relative Concentrations at the Intakes l
l The tracer concentrations at the intakes to the Control Complex were gener-ally lower than those on the roof. As shown in Table 5-1, the mean and max-l imum Chi /Qs for Locations #2 and #4 were lower than those for Locations #1,
- 3, and #5. The average for the two intake locations was 2.7E-5 s/m3, versus the average of 5.5E-5 s/m3 for the three roof locations--about a factor of 2 difference.
The average maximum for the intakes was 6.4E-5 s/m3, compared to the average maximum of 1.8E-4 s/m3 for the roof loca-tions--about a factor of 3 difference.
Not only were the average concentrations similar at the intakes, but the concentrations correlated well from test to test.
As shown in Table 5-1, the correlation was 0.91 for Locations #2 and #4. The highest and second highest concentrations at each intake occurred during the same two tests, 24 and 26. As shown in Figure 5-1, this correlation was consistent over the l
range of observed concentrations. No other combination of locations had this high a correlation. Otherwise, in general, the lowest correlations were between the most separated locations. The relatively high correlation of 0.87 between Locations #4 (intake) and #5 (NW corner) was probably asso-ciated with the phenomenon (reported in Section 4.3) of smoke to wrap around the back of the Control Complex.
This general trend for Chi /Os to be lower at the intakes than on the roof is also apparent in the test-by-test measurements (Tables 4-4 and 4-5 and Appendix B).
5.2 Dispersion by Source The maximum Chi /Q at the intakes (Locations #2 and #4) during each test were not always attributable to the same source.
Since dual tracer 5 were avail-able during 24 of the tests, the results could be compared.

The tracer SF6 was always released from Source 3, the stack.
Up through Test 17, the SF6 was released from a tube at the top of the stack.
The tube lay on the top and extended over the west edge by several inches.
For Test 18 and subsequent tests, the tube was held in place by a rope on a pul-ley at approximately 1 m below the top of the stack, on the west side. This minor change in location was made to minimize any possible entrainment of the tracer into the exhaust of the stack vent.
However, based on the smoke l
releases (Section 4.3), the amount of entrainment was probably minimal.
4 The BCF tracer was always released from the lee of one of the containments, Source 1 or 2, that correspond to Unit 1 and 2, respectively. The BCF was released from a tube about 1 m above the roof level of the Intermediate Building; the tube was taped to the side of the containment.
As illustrated in Figures 5-2 and 5-3, neither source (the containment or 4
stack) predominated in giving the highest concentrations--neither at the in-takes nor on the roof. However, the stack source was slightly more often associated with the higher concentrations at most of the locations.
Statistical data in Table 5-2 showed a similar tendency in that the average concentration at all five locations was slightly higher when associated with the stack rather than a containment source.
3 In general, the measured concentrations from the stack were on the average
}
24% higher than the ones from the containments. This 24% difference held l
for the respective averages of the roof and intake locations.
5.3 Dispersion by Wind Direction i
j The wind direction at the 10-m level of the PMT was converted to sector.
Each sector was 22.5* wide, the first being centered on north.
Going clock-4 wise, the sectors were assigned increasing numbers. Thus north-northeast was 2; northeast, 3; etc. The two highest concentrations at each intake occurred concurrently during tests 26 and 24.
1 5-3 NUS COAPORATION
Attcnment 3 PY-CEl/NRR-2076L Page 59 of 167 During tracer releases the sectors northeast (3) through south-southeast (8) were experienced. As shown in Figure 5-4, the highest Chi /Q observed was associated with winds from the east.
In general, winds trom the east-northeast and east yielded the highest concentrations--both to the intakes a
and to the roof.
As estimated by the Murphy and Campe methodology (see Section 1.2), sectors north through southeast were the most likely to result in an influence on I
the intakes for releases from the containments or stack.
For other sectors, the concentrations were< negligible.
Clearly, the directions to result in high concentrations to the intakes were experienced during the-tracer releases.
Also, the test results tend to confirm the Murphy and:Campe assumption, j
5.4 Dispersion by Stability Class The atmospheric stability class during the tests was determined from the delta T measurements at the PMT.
Stability classes ranged from A (very un-stable) to G (very stable) during the tracer releases.
The highest concentrations were associated with D (neutral) to E (slightly stable) conditions, as shown in Figure 5-5.
This was truc both at the intakes'and on the roof. A considerable number of data points occurred in these two stability classes.
i The occurrence of the' highest values in these classes differed from that expected from Murphy and-Campe (see Section 1.2).
For Perry, the method-ology indicated controlling conditions that were associated with stability j
class F.
Even when-the formula for Chi /0 was normalized for the wind speed (U), the resulting ChiU/Q calculated for each stability class indicated that j
the highest was expected with very stable (G) conditions (because stability class G had the most limited dispersion factors).
However, as shown in Fig-i ure 5-6, the observed concentrations normalized by the PMT 10-m wind speed j
still were highest in association with neutral and slightly stable condi-tions, rather than very stable (G) conditions. This was true for each of 5-4 NUS COAPORATION PY<El/NRR-2076L i
Page 60 of 167 the five locations for these tests which included 6 tests (12 data points at each receptor) of F or G from the E, ESE, SE, and SSE sectors. Thus, the i
Murphy 'and Campe methodology was not supported by the data from the tracer study.
5.5 Dispersion by Wind Speed 1
q Wind speed seemed to be the dominant meteorological factor related to high concentrations for those tests in which the wind was blowing towards the 4
receptor locations.
(Wind speed was taken from the 10-m level of the PMT.)
1 As shown in Figure 5-7, at the intakes the highest observed Chi /0s increased i
with increasing wind speed to a wind speed between 2.5 and 3.0 m/s, then i
leveled off. At higher wind speeds, the highest Chi /Qs tended to be the same, with a hint of drop off. At the roof receptors, there was a clearer hint that there may be a drop off in the highest Chi /Qs above 2.0 m/s.
1 In summary, as shown in Figure 5-7, the tracer study captured events of wind speeds in the 2 to 3 m/s range that appear to be associa,ted with the highest Chi /Qs. Thus, the highest Chi /Q expected at the intakes from the contain-ments and stack would be approximately 6.8E-5 s/m3 (Test # 26).
5.5.1 Stability Class The atmospheric stability class associated with the highest concentrations was E, as shown in Figure 5-8.
Class E (slightly stable) was followed by D (neutral). Classes F and G, the two most stable classes, were associated with the lower half of the distribution of observed concentrations.
The distribution was different than the typically anticipated one in which the highest concentrations would be expected with the most stable I
conditions.
However, the stable conditions may have given some protection to the intakes (halfway down the west f ace of the Control Complex) by limiting the amount of effluent to disperse downward from the sources, or 5-5 NUS COAPORATION
Auctment 5 PY-CELHRR-2076L Pqc 61 of l67 the wind direction nay not have been sufficiently direct (six tests with E, ESE, SE, SSE) to experience higher concentrations at the receptors.
i 5.5.2 Sector l
The wind direction sectors associated with the highest concentrations were east-northeast and east, as shown in Figure 5-9.
This was the pattern seen before without regard to wind speed.
i '
However, dependency on wind speed was evident even within a sector.
For example, in the east sector (E) the concentration dropped with lower speeds i
in the 1.5 m/s range.
1 5.5.3 Source The source associated with the highest concentrations at the intakes was the stack (#3), as shown in Figure 5-10.
The highest concentrations associated with the stack source seemed to drop off more rapidly with increasing wind
{
speed than the drop off for all sources.
In fact, the highest concentra-tions associated with Unit 1 or 2 (#1 or #2) may have been increasing with wind speed in the 3 to 5 m/s range.
The peak for the stack as a source and its marked peak may have resulted from the relatively undispersed plume making its way to the region near the intakes. With increasing wind speeds the plume became more dilute.
The pattern at the roof locations, as shown in Figure 5-11, was not the same as for the intakes. However, the stack source seemed more dominant than
{
either of the two containment sources.
Apparently, the initial mixing in the lee of the containment and in the region between the two containments was sufficient to reduce the chance of causing the highest concentration from containment releases at the west end of the Control Complex, where all five receptors were located.

I 5.6 Further Analysis by Wind Speed and Source I
As a result of the analyses presented, wind speed, stability class, and 1
source location were judged to play important roles in influencing the peak 1
Chi /0 at the intakes for winds blowing toward (E and ENE, primarily) the Control Complex intakes. However, stability class probably plays a less important role because of the breakup of thermal stratification by the turbulence caused by the buildings.
Therefore, additional analyses of the data were performed to present Chi /Qs and associated sources in relation to different wind speed data.
The 10-m i
wind speed at the PMT had been used in the analyses thus far. The following i
analyses make use of the following data:
j PMT (60-m level)
CCR (10-m level) 1 5.6.1 PMT (60-m Level)
The 60-m wind speeds at the Perry Meteorological Tower (PMT) were selected because they might provide a better representation of the general airflow at the roof of the Control Complex than the 10-m speeds. The roof of the Control Complex (CCR) is approximately 27 m above ground level.
As supported by the information in Appendix C, the winds during the tests on the CCR were different than those reported at the PMT and UTT 10-m levels.
The roughness caused by structures in the Building Complex had the potential to break up thermally stratified air, as indicated by stable conditions based on delta T at the PMT.
In addition, at night the heat stored in the structures of the Building Complex nay have destroyed some thermal stratification as air moved into the Building Complex. Under such conditions, the 60-m level speeds may correlate better with those at the CCR.
As the range of wind speeds at the 60-m level was different than at the 10-m level of the PMT, the plots of Figure 5-12 were different from thor,e in Fig-5-7 NUS CORPOAATION
PY-CEl'NRR-2076L Page 63 of 167 I
l ure 5-10.
As shown in Figure 5-12, concentration at the intakes peaked and dropped off more markedly with increasing wind speeds.
{
By source, it appeared that the highest concentrations associated with the stack (Source 3) peaked at a lower wind speed than those associated with the containments (Sources 1 and 2).
When all the intake data and the roof data are aggregated, as shown in Fig-ure 5-13, they support the conclusion that the range of conditions causing the highest concentrations were experienced during this tracer study.
Both the intake and roof data exhibited peak concentrations in the mid-range of speeds experienced during the study.
5.6.2 CCR The winds from the 10-m level of the CCR, while influenced by the roughness of the Building Complex, were probably the best representatives of the
{
speeds encountered by the tracer plumes. The lack of correspondence between the PMT 10-m level and the CCR is demonstrated in the plots presented in Appendix C.
The lack of correspondence is attributed to the mechanical and thermal effects of the Building Complex.
As shown in Figure 5-14, the highest concentrations clearly peaked around 2 to 3 m/s. They clearly dropped off with increasing wind speeds--no matter what the source was. The aggregated data for intakes and for the roof exhi-bited the same distribution as shown in Figure 5-15.
The conditions resulting in the highest concentrations were experienced dur-ing this tracer study. They were associated with winds of 2 to 3 m/s (as measured at the CCR) that blew towards the receptors from the sources (east-northeast and east winds).
An envelope drawn to the highest values measured at the intakes was drawn in Figure 5-15 for the intakes. The maximum Chi /Q associated with this enve-lope line was approximately 7E-5 s/m3 I

percent were initial (first)-hour tests; 12 percent, second-hour; and 8 percent (each), third-hour through ninth-hour.
In other words, 88 percent of the releases were in non-independent hours of release (2+ consecutive hours).
No evidence was noted of a possible buildup of tracer material within the Building Complex in the vicinity of the west end of the Control Complex.
There was a peaking in relative concentrations at the window of 4 to 8 consecutive hours, as shown in Figure 5-16.
In shorter or longer periods of consecutive hours the Chi /Qs dropped. The peaking simply represented the occurrence of direct wind direction and speeds that have been shown to cause l
the higher concentrations. Observation of smoke releases confirmed that material tended to rapidly move out of the Building Complex.
l Therefore, data from consecutive hours of testing were probably representa-tive of independent hours.

6.0 CONCLUSION
S i
The tracer study within the Building Complex at the Perry Nuclear Power Plant involved 30 test hours in September 1985. An analysis of the data was presented in Section 5.
Conclusions were drawn from the analyses pertaining
{
to the objective of the study to determine a new dispersion estimate at the air intakes to the Control Complex.
~
The results of the tracer study support a new estimate of dispersion for use in determining control room habitability at Perry. The estimate was appli-cable to a one-hour value of atmospheric dispersion in the Building Complex at Perry from either of the containments and the stack to the two air intakes for the Control Complex.
i The new estimate of dispersion is a Chi /Q of 7E-5 s/m3 This new value represents a reduction by a factor of 50 relative to the previously existing er,timate of 3.5E-3 s/m3 The previous estimate was based on the Murphy and Campe (1974) methodology that was designed for generic application to any building configuration. The new estimate is applicable to the particular configuration of the Building Complex at Perry since it is based on site-specific dispersion tests.
A sufficient variety of meteorological conditions was experienced to ensure that the poorest dispersion was experienced.
Analysis of the tracer data from 25 tests demonstrated that wind speed was the most important meteoro-logical variable to influence the control of the receptor concentration dur-ing oncoming winds. Maximum concentrations were observed within the range of speeds observed during the tests.
The atmospheric stability class was important to a lesser extent; peaks were associated with classes well within the range experienced during the tests.
6-1 NUS CORPORATION
f Aurenmem a PY-CEl/NRR-2076L Page 83 of167 Concentrations experienced at the intakes on the west face of the Control I
Complex were lower than those immediately above on the roof. Observations of smoke releases tended to confirm the patterns--that smoke often moved well away from the Control Complex before being mixed downward toward the intakes.
Maximum concentrations were not conclusively associated with either the stack or containment themselves, although there may be a slight favoring of the stack source. The lack of differentiation was attributed to the fact that the containment releases got more initial mixing than did the stack I
releases, while the stack releases starting higher above the roof of the Control Complex were less apt to be moved to the intakes. These phenomena were observed during the smoke releases.
l I
The new one-hour average of dispersion, 7E-5 s/m3, was derived by envelop-ing the maximum concentrations observed at the intakes.
The enveloping was done on a plot of measured concentrations versus wind speed measured on the roof of the Control Complex. The new estimate represents the peak value of the envelope.
This new estimate was judged appropriate for the application to control room habitability for the following reasons:
All the concentrations measured were within an order of magnitude o
of each other, The peak occurred well within the range of meteorological condi-
~
o tions experienced during the tracer study.
l The peak within a range of speeds was consistent with recognized l
o phenomenon that at low speeds the release may move off from the building with little motion downward to the intakes, and that at high speeds the release will be diluted even though more of the release plume may be mixed down to the intakes.
6-2 NUS CORPORATION PY<El/NRR 2076L g
Page 86 of167 o
The new estimate for use in evaluation of control room habitability is roughly analogous to a probabilistic value--at approximately the 5th percentile, as presented by Murphy and Campe (1974).
The maximurr value enveloped is probably very near the maximum possible, The literature (Hosker,1982) suggested that a reduction--compared o
to an estimate based on Murphy and Campe--on the order of 10 to 100 through the use of site-specific study was not unreasonable.
o The maximum derived from the envelope is not applicable to both in-takes simultaneously. The envelope was drawn to the points from both intakes. Although the observed values at each intake tracked closely, one or the other was usually higher at a given hour.
The tracer data incorporated any possible hour-to-hour buildup in 0
the atmosphere around the Building Complex since most tests were conducted in hours immediately succeeding previous ones, j

SUMMARY
j An atmospheric tracer study was conducted in the Building Complex of the Perry Nuclear Power Plant (PNPP), The Cleveland Electric Illuminating Com-i pany. NUS Corporation, with Tracer Technologies as subcontractor for release and measurement of the tracer materials, conducted the study at Perry in September 1985. The PNPP is located on the shore of Lake Erie about 45 miles northeast of Cleveland, Ohio, l
l l
The primary objective of the study was to demonstrate that a reduction in the control room Chi /0 (atmospheric dispersion) is appropriate for Perry.
l Chi /Qs are normalized concentrations that represent atmospheric dispersion l
and would be used in determining dose estimates. The previous calculated one-hour average (applicable to O to 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />) Chi /Q for control room habit-l ability for releases from the containment was based on the generic Murphy and Campe (1974) methodology. The previously existing estimate of the ini-tial Chi /Q is 3.5E-3 seconds per cubic meter (s/m3) using the seven-year l
meteorological data base for PNPP.
Thirty test hours were conducted during the field study period from September 18 to 25, 1985. These involved measurements of meteorological data at three locations, including the Perry Meteorological Tower. The tests involved the release of tracer gases from two locations, sampling of the tracers at receptors, and/or release and observation of smoke.
Twenty-four of the 25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> with tracer data involved two tracers.
Releases were from 3 different sources.
Concentration measurements were made at 5 outside locations plus a control location.
A revised estimate of dispersion (0 to 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> value) was determined on the basis of the data.
A Chi /0 of 7E-5 s/m3 was selected, based on the enveloping of the maximum observed concentrations and consideration of the representativeness of the data set and the application of the value.
The.new estimate affords a factor of 50 reduction over the previously existing estimate, based on the Murphy and Campe methodology.
