<p>For the release of SCALE 6.2.3, several new input cards were implemented
into Polaris to model boiling water reactor (BWR) geometries and
neutron/gamma detectors, which requires a gamma transport calculation.
Moreover, improvements to existing input cards were implemented, along
with the ability to specify time-dependent state properties and the
ability to specify one or more depletion histories. This appendix

documents the SCALE 6.2 input cards that were included in the Polaris
input format which are accessible as part of the release of SCALE 6.3.</p>
<p>The old input cards are not available <em>by default</em> with SCALE 6.3, and
should be considered deprecated. To maximize backwards compatibility for
input files developed with the original SCALE 6.2.0 release, the old
input options are available if the input file begins with =polaris_6.2.</p>
<p>The following input cards were introduced in SCALE 6.3 and are not
available by default in SCALE 6.2:</p>

<p>The <strong>pin</strong> card is one of the basic building blocks of the assembly
model. It is the only geometry component which allows an integer (<em>Int</em>)
identifier as well as a <em>Word</em>—all other geometric identifiers use
<em>Word</em>. Note that the materials are required, except for the last
M<sub>out</sub>, which can be used to overwrite the material given by a
<strong>channel</strong> for the outermost region in the pincell. The various pin
cell meshing options are displayed in <a class="reference internal" href="#fig3-2a-3"><span class="std std-numref">Fig. 54</span></a>. Note that extra
rings in the radial zones create equal area regions, whereas rings in
the outermost region create equal distance divisions between the last
radius and the pincell boundary. Extra sectors create additional
azimuthal divisions. A negative value of sectors is allowed and can be
used to rotate the sector mesh by a half angle, e.g., ns=4 looks like ⊕
and ns=-4 looks like ⊗.</p>
<p>The total number of cells used in the transport calculation is
determined from both the number of rings and the number of sectors. With
the MoC transport solver, the fidelity of the solution is also dictated
by the number of azimuthal and polar angles and ray spacing. These
parameters are changed on the <strong>option&lt;KEFF&gt;</strong> card.</p>
<p>Due to self-shielding and depletion, each cell could be modeled as a
unique material with its own cross section data. However, this is
prohibitively memory intensive and typically not necessary. The
<strong>shield</strong> card provides the mechanism to control the additional
self-shielded materials introduced.</p>

<p>The <strong>bu</strong> card initiates a calculation for a given sequence of
cumulative burnups. A burnup or time card usually follows a <strong>power</strong>
card, the two effectively specifying the power history. If multiple
burnups are given, then the <strong>power</strong> card must have either a single
power or a list of powers the same size as the list times. A value of 0
is implicit at the beginning of the first burnup list. Multiple
burnup/time cards may be specified in an input. This can be convenient
for switching units or changing from burnup-based to time-based
depletion. Internal automatic substeps are always in effect unless
modified with the <strong>option&lt;DEPL&gt;</strong> card.</p>

<p>The <strong>t</strong> card initiates a calculation for a given sequence of
cumulative/absolute times. One of the time cards (<strong>t</strong>, <strong>dt</strong>, or
<strong>ti)</strong> is required to model periods of decay in conjunction with
<strong>power</strong> 0. Otherwise, the time card <strong>t</strong> is similar in functionality
to the burnup <strong>bu</strong> card but with different units.</p>

<p>Comments:</p>
<p>The geometry version of the <strong>state</strong> card is used to declare which
geometric elements are present in the system. The geometry version of
the <strong>add</strong> card is useful for performing branch calculations for
reflector nodes. Note that an assembly geometry must be present to
perform a calculation.</p>
