Experiment(International StandardProblems):<br />

[SP-16 HDR DBA Va183 5 Early M-H M-H The explichflowsolverwas used, with<br />

(V44) blowdown, W0183 no <strong>for</strong>ced convection modeling. Slight<br />

mid-elevation overprediction <strong>of</strong> the peak blowdown<br />

injection <strong>of</strong> pressure resulted. Very good prediction<br />

steam <strong>of</strong> early-time break-room to adjoining<br />

room differential pressure was found.<br />

ISP-23 HDR DBA Kar89 33,60 1.10 H M The implicit flow solver was used, with<br />

(T31.5) blowdown, <strong>for</strong>ced convection modeling.<br />
