                                ABSTRACT

     The Phoebus 2A Experimental Plans IV and V were full-power nuclear
reactor operations conducted as part of Project Rover.

     Experimental Plan IV was conducted on June 26, 1968 and Plan V was
conducted on July 18, 1968.  Both tests were at the Nuclear Rocket
Development Station, Jackass Flats, Nevada.

     This report, covering large particles of high activity, includes
particle deposition concentration at various distances; and gross physical
characteristics, chemical composition, and gross and specific radioactivity
of these particles.

     Survey results indicated wide spread deposition for Plan IV with no
defined hotline.  Plan V survey results indicated the major deposition
between 13° and 21  from Test Cell C.

     The particles were porous and fragile and had a metallic black
appearance.  Sizes ranged from eight to 200 um on Plan IV and seven to
163 |jjn on Plan V.  The use of a latex spray reduced the shattering of
particles during collection and separation:

     The chemical composition of the particles was primarily uranium oxides.
Fall velocity was determined in free air and liquid.

     Gross activity of the particles was 10  - 10   fissions on both runs.
Alpha activity was not determined because of the method of mounting the
sample on glass slides with collodion.  The primary radioisotopes found
by gamma spectroscopy were those of Sr, Zr, Ru, I, Ba, Mo, and Ce.

I.    INTRODUCTION

      The Phoebus 2A reactor engine Experimental Plans (EP's) IV and V were
conducted on June 26 and July 18, 1968, as part of Project Rover; Los Alamos
Scientific Laboratory (LASL).   The experiments were conducted at Test Cell C,
Nuclear Rocket Development Station (NRDS), Jackass Flats, Nevada.  The
power integrals for the plans are listed in Table 1.

      This report contains the results of work performed by the National
Center for Radiological Health at the Southwestern Radiological Health
Laboratory (SWRHL) as outlined in the "Project Proposal for Reactor Effluent
Studies - Particulate", August 1, 1967.

II.   STUDY OBJECTIVES

      The objectives presented in the Project Proposal that were accomplished
in this study were the determination of:
      1.  Deposition concentration (particles per m^) profile of particles
          both downwind and normal to the downwind axis.
      2.  Line of maximum deposition.
      3.  Physical,  chemical,  and radiometric characteristics of the radio-
          active particulate material collected.
      4.  Particle size versus distance.

III.   FIELD ASSAY

      A.   Methods of  Collection
          Sampling routes  were  pre-established at approximately 15, 25,
      40,  50,  and 110 miles  from Test  Cell C, along existing roads.  The
      distances between sampling locations and areas surveyed at each
      location are listed  in Table  2.   Specific  instructions listed in
      Appendix A were given  to  each sampling team.

      B.   Field Results  -  EP-IV
          Figure 1  shows the area  surveyed along with particle concentration
      at  each location.  The results of the  particle survey for EP-IV are
      presented in  Table A-I.  The table  gives azimuth and distance of the
      location from Test Cell C, total particles found at a location and
      the particle  concentration.   Although  the major effort was exerted
      between 30 and 113   from Test Cell C, a search was conducted on
      Highway 95 (147° to  164 ) because aerial data showed a portion of
      the cloud passed over that area.  No particles were found along
      Highway 95.

          The change in  average deposition concentration with distance is
      shown  in Figure 2.   Curve A  illustrates the ratio of the total number

of particles found along an arc to the total positive location areas
versus distance from Test Cell C.  Curve B is the ratio of the
total number of particles found along an arc to the total area sur-
veyed between edges of the deposition pattern.*  As expected,  both
curves show a decrease in concentration with distance.

    On Run + 1 and 2 days, nineteen particles which measured greater
than 100 mR/hr (open probe on an E-500B) were picked up for a
special biological study.  These particles were collected within a
one mile radius of CP-1, but were not considered in concentration
calculations.

C.  Field Results - EP-V
    Survey results for EP-V are presented in Table A-2.  Figure 3
shows sampling locations and particle concentrations.  The major
activity was found between 13  and 21  with no defined hotline.  The
lack of definition of a hotline may be due to weather or the starting,
stopping, and restarting of the reactor.

    A three dimensional representation of particle deposition
concentration is shown in Figure 4.  The concentrations are in
particles per square meter.

    The change in average deposition concentration with distance is
shown in Figure 5, in the same manner as Figure 2.  The curves show
a decrease in concentration with distance.
*For example, on the 40 mile arc, after EP-IV, a total of three
particles were found between 49 and 65 degrees.  One particle was
found at each of three locations (positive area = 150 m^).   For
Curve A this would represent a value of 3/150 or 0.02.  A total of
twelve areas (600 m2) were surveyed between 49 and 65 degrees.  For
Curve B this would represent a value of 3/600 or 0.005.

      D.  Discussion of Field Results
          The field results are similar to previous tests (1).   Weather
      at the time of the EP-IV run showed an unstable vertical temperature
      structure with light and variable winds.  Inspection of field data
      indicated a widespread deposition with no defined hotline which was
      probably due to the light and variable winds.  The peak particle
      concentration is lower by a factor of two than was anticipated from
      post-run predictions (4).

          On EP-V, the weather conditions were more stable than on EP-IV.
      The multi-peak deposition patterns, as shown on Figure 4, may be
      due to wind shear at the time of the run (3).  The particle
      concentration for EP-V is higher by a factor of three than was
      predicted (4).

          Both experiments showed a decrease in particle concentration
      with distance, Figures 2 and 5.  Curves A, on both figures, had
      approximately the same slope.  These curves are similar to those
      for previous tests (1) for the same distances.

IV.   LABORATORY ASSAY

      All samples were returned to SWRHL for analysis.  After the radio-
active material was separated from the matrix, physical.measurements were
made.  On selected samples, radiometric and microprobe analyses were
performed.'  Analytical procedures were the same for both EP-IV and EP-V.

      A.  Separation and Location
          Initial separation was performed by dividing the sample into
      small portions and checking each portion with a laboratory radiation
      monitor.  The portions containing activity were mounted on 1" x 3"
      glass slides using collodion.

-------
    The use of latex (see Appendix A) during collection kept particle
fracturing to a minimum.  In a few cases more than one active portion
was obtained from a sample, but this was minimal when compared with
previous particle separation (1).  A radioautographic technique was
used to precisely locate the radioactive material.  After location,
the collodion used to hold the material was starred for future
reference.

B.  physical Characteristics
    A microscope was used to determine the appearance and size of
the material.  Most particles were large enough to be sized at
lOOx magnification.  The radioactive material appeared to be porous,
black to reddish color, and somewhat spherical.  Some of the
particles were quite fragile and shattered when touched.

    All particles collected from both tests were sized.  Sizing was
accomplished using a filar micrometer eyepiece in the microscope
to measure the maximum dimension and the dimension perpendicular
to the maximum (9).  Table A-3 presents the size data for EP-IV.
Table A-4 presents data from the EP-IV special samples, which were
collected in the CP-1 area without regard to area covered; therefore,
no specific location is given.   Table A-5 presents the size data
from EP-V.  The equivalent diameter, defined as the square root of
the product of the two measurements, is given in parentheses,
Tables A-3 and A-5.  Some specimens had more than one particle (due
to fracturing) and an equivalent diameter was not calculated.

    Fall velocity was measured on a few selected particles using
an air column and a liquid column.  One particle from EP-IV
(Sample No. 399) and three of the most active particles from EP-V
were dropped in free air in a vertically mounted, one-inch diameter
(I.D.) glass tube.   Two Nal(Tl) detectors were positioned 10 feet
apart on the tube.   The signals from the detectors were fed into a
multi-channel analyzer operating in the multi-sealer mode.  Fall-time
                             10

-------
    was determined from the interval between detection of the particle
    at each detector.   Each particle was dropped at least twice;  two
    were dropped four times.   The average of these times was used in the
    calculations.  Data from the tests are presented in Table 3.

*Fluid Viscosity - 2.67 centipoises
 Fluid Density - 0.883 grams per cubic centimeter
        An attempt was made to determine the density of the particles
    from Stokes1, Rubey's,  and Oseen's equations.(8).   Values  of
    1.51, 15.7, and 2.49,  respectively,  were obtained.   The wide
    variation in calculated densities is due to the non-applicability
    of the equations used.   Due to the relatively large size and mass,
    all particles had Reynolds numbers outside of the range for which
    the equations were valid.   An empirical calibration will be performed
    with similar material.   These results will be reported in  a later
    paper.

    C.  Radiometric Analysis
        All specimens from EP-IV were beta counted and gamma scanned.
    Alpha counting was not attempted because the method of mounting the
    material with 30% collodion covered the sample.  All specimens  from
    EP-V were beta counted and 22 were gamma scanned.

        Beta activity is reported in dpm, fissions*, and picocuries for
    individual specimens.   Table A-6 presents data for EP-IV as of
    July 9, 1968, while Table  A-7 presents data for EP-V as of
    July 23, 1968.  Locations  (azimuth and distance from Test  Cell  C)
    are also given in each table. ;Eleven specimens from EP-IV and  ten

                                  12

-------
from EP-V were beta counted over an extended period of time to follow
decay and to determine the average maximum beta energy.  Decay curves
of the samples plotted on log-log paper had essentially the same
shape and slope indicating sample similarity.  Comparison of the
decay curves with published data (5) shows reasonable agreement
with gross mixed fission product decay, Figure 6.

    Beta absorption tests, using aluminum absorbers, were run
concurrently with beta decays.  The average maximum beta energy for
each specimen was determined from the half-thickness value of
aluminum absorbers and was used to select the counting efficiency.
All absorption curves were about the same shape.  The average
maximum beta energy for the specimens was about 1.3 MeV and no
trends were observed as a function of age.  The average maximum
beta energy is close to the 1.2 MeV reported for gross mixed
fission products (6).

    Gamma scanning was performed on a multi-channel analyzer with
a 4" x 4" Nal(Tl) detector.  The data were reduced by hand using a
series of gamma scans to obtain qualitative and quantitative
information.

    Table A-8 presents the isotopic data for EP-IV.  There were
               91    97        239
indications of   Sr,   Zr, and    Np, but lack of sufficient
counting data made quantitative values questionable.  The reported
values have been extrapolated to 1409 on run day (6/26/68).

    Table A-9 presents the isotopic data for EP-V.  These values
have been extrapolated to 1608 on run day (7/26/68).  The percent
of each isotope due to EP-V is given in parentheses at the top of
the column.  This percentage was calculated from the power integrals
from each run and the decay time between the runs.

D.  Microprobe Analysis
    Electron microprobe and X-ray diffraction analyses were performed
on seven specimens.  Microprobe examination was made to determine
the elemental composition of the specimen and X-ray diffraction
analysis was made to determine the chemical composition.   The micro-
probu and X-ray diffraction data are reported in Table A-10.  The
elements and compounds are listed in order of decreasing concentration.
Samples D-l and D-2 were samples from the fall velocity tests, but
individual particles could not be recovered from the liquid column
for microprobe or diffraction examination.

    Sample 417 indicated niobium with the electron microprobe, but
X-ray diffraction did not show compounds of niobium.  While this
may fie an artifact of the orientation of the analysis, this suggests
that niobium was not a major component of the particle.

E.  Discussion of Laboratory Results.
    The size data from EP-IV were not suitable for size-frequency
distribution calculations because of the small amount of non-
fractured particles.  The size-frequency distribution for EP-V was
calculated using an equivalent area diameter for those particles
that were not fractured.  On the 15 mile arc, 27 of 41 (66%) were
not fractured and were used in the calculations.  On the 25 mile
arc, 24 of 33 (73%) were used.  The difficulty in trying to "glue"
fractured particles together limited the use of the remaining
specimens.

    The calculated (7) results of the size-frequency distribution
are presented in Table A-ll.  The graphical results are presented
in Figure 7.  The larger geometric mean diameter at the 25 mile arc
is caused by the difference in size distributions below 70 (JL.  This
difference may be real, but is probably due to the relative small
numbers of particles from each arc.

-------
    A linear regression of activity and size for EP-IV gave the
following equation:
         Fissions x 1010 = 0.033 x size (JJL) - 0.165

    The value 0.033 had a range of 0.009 to 0.056 at the 95% C.L.,
whi^i the constant -0.165 was between -1.28 and 0.96 (95% C.L.).
A correlation coefficient of 0.73 was found, which indicates a
fairly strong correlation between size and activity, even though
a limited amount of data were available.  The data are presented
graphically in Figure 8.

    The correlation of activity and size for EP-V data gave the
following equation:
         Fissions x 1010 = 0.105 x size (JJL) - 3.4

    The best estimate of the relationship between X and Y, 0.105,
had the range of 0.062 to 0.148 (95% C.L.).  The best estimate of
the constant, -3.4, had the range of -6.45 to -0.35.  A correlation
coefficient of 0.573 was found for this data.  Even though the EP-V
correlation coefficient is not as high as the EP-IV coefficient, it
does indicate the two variables are not independent of each other.
The data used are presented graphically in Figure 9.  The circled
points in Figure 9 are EP-IV data.  It can be seen that they fit
within the range of values found for EP-V data.

                              235
    Theoretical abundances of    U fission products at one hour
                          99
after fission relative to   Mo, were obtained from Bolles and
Ballou (5).  Isotopic values identified for each sample were also
                         99
related to the amount of   Mo found.  These ratios are presented
in Table A-12.  The ratio calculated for each sample was divided by
the corresponding ratio calculated from Bolles and Ballou to
determine an "enrichment factor" for the isotope relative to the
amount expected.  These enrichment factors are presented in Table A-13.

      relative to the other isotopes.

V.    INTERPRETATION OF FIELD AND LABORATORY RESULTS

      Comparison of activity per unit  area and distance shows a decrease
of activity per unit area with distance for EP-IV, Figure 10.  The  activity
per unit area is calculated by dividing the activity for an arc by  the
total area*.

      Figures 8 and 10 indicate a possible correlation of size and
distance for EP-IV.  However, the limited number of particles found on
this EP does not warrant the expansion of the data.

      Table A-ll and Figure 11 both show a slight increase of particle
size with distance between 15 and 25 miles on EP-V.  Figure 10 demonstrates
this, also, with an increase in activity from 15 to 25 miles.  The
correlation between Table A-ll and Figure 10 is consistent with the
positive correlation found between particle size and activity.

VI.   SUMMARY

      Both' EP-IV and EP-V of the Phoebus 2A reactor ejected fragile
particles, ,^which registered several mR/hr to several hundred mR/hr at a
few inchQft with the open probe of an E-500B.  Particles were located and
         *
sampled out to about 40 miles.  Field  results were similar to previous
reactor tests.  The material collected had properties similar to that
collected following previous tests. Electron microprobe and X-ray
diffraction analysis showed that the particles were composed of reactor
core material.
*Total area is the total plot area as defined on Page 5.

                        Sampling Instructions

1.  Drive to the designated area.

2.  At a distance of at least 50 feet from the road, place a one-meter
    square template on the ground as many times as necessary to obtain
    the specified plot area.  (Example - an arc at 16 miles, 30 place-
    ments of the template would be required).

3.  With an E-500B survey instrument, search the area inside each
    template for hot spots.  Trace a path back and forth across the
    area, sweeping a one foot wide path, with the probe held
    horizontally six inches above the ground.  The beta shield will be
    opened and facing downward.
