Code Manual for CONTAIN 2.0 - Federation of American Scientists

into CONTAIN. The obsolete VANESA keywords from earlier CONTAIN versions include:
CONCOMP, EDITDELT, REBAR, FDELT, DIFCO, BUBD, PTBB, PTDIA, OXPOT, MOLEC, ~
STABLE, and VROVR. If any of these keywords are present in an input block, the associated input
values will simply be discarded and a warning will be written to the error file notifying the user that
the input is obsolete. In the case of the EDITDELT keyword, a VANESA output edit is now
generated whenever a CORCON edit is also generated. This is governed by the input given in the
CORCON TIMES block. In the case of the CONCOMP, the concrete type seen by the VANESA
model is now taken from the CORCON input. This is also true of the REBAR keyword where the
VANESA modeling now uses the appropriate rebar fraction from the CORCON input block. With
regard to the obsolete FDELT keyword, the VANESA modeling now uses the same calculational
timestep as CORCON. The values for the remaining obsolete keywords are set fixed at the
previously defined defaults.
SCRUB the keyword to activate the VANESA aerosol scrubbing model for overlying
pools. The depth of the coolant pool used by the scrubbing model is
determined from the conditions of the pool layer.
BSIZI the initial bubble diameter for pool scrubbing. Default = 0.01. (m)
= bsizi
EOI the keyword used to terminate input. The CONCRETE, PHYSICS,
CORCON, EMISIV, VANESA, and SCRUB blocks all must be terminated
with the EOI keyword.
14.3.2.4 Intermediate LaverS. This input block is used to define the characteristics of an
intermediate layer in the lower cell. Like the concrete layer input, the intermediate layer input differs
for problems with and without core-concrete interaction modeling with CORCON. The two sections
that follow describe the intermediate layer input for problems without CORCON and problems with
CORCON, respectively.
14.3 .2.4.1 Intermediate Layer Input Without CORCON. Multiple intermediate layers may be
defined in problems that do not include core-concrete interaction modeling with CORCON. The
number of intermediate layers, “jint,” is specified in the cell CONTROL block. The intermediate
layer definition block should be repeated “jint” times. The fmt INTERM layer input block
corresponds to the lowest intermediate layer in the lower cell system. The layers proceed upward
in the order that they are defined, with the last intermediate layer corresponding to the uppermost
of the intermediate layers. Each such intermediate layer will consist of one node.
Descriptions of the SOURCE, Q-VOL, and HT-COEF keywords and associated input are the same
as described for the CONCRETE layer without CORCON (see Section 14.3.2.3.1). Detailed
descriptions of these keywords and their associated input are therefore not repeated in this section.
