๐ธ Before you spend $500K on a reanalysis, make sure you actually have to. While youโre at it, #freedave.
The plant is pursuing an extended power uprate. Leadership needs to know if the existing containment analysis holds at EPU conditions before committing to a full reanalysis.
๐๐๐ฏ๐'๐ฌ ๐จ๐ฅ๐ ๐ฐ๐๐ฒ: Half a day finding the calculation, then a slog through manual parameter comparison. He has to write memo under time pressure before the Thursday 2pm meeting.
๐๐ข๐ญ๐ก ๐๐จ๐ซ๐๐ข๐๐ง: Containment parameters cross-referenced against EPU conditions. Comparison table โ containment design pressure, LOCA mass and energy release, peak temperature, post-LOCA hydrogen, ECCS back-pressure. Quick recalculations using design basis info and Python libraries. Flags for further analysis where needed.
Dave reviews the table, calls the containment engineer, and walks into the meeting with a recommendation: "Do QA runs for M&E release and hydrogen. Pressure margin is tight but holds. Here's the scope." That's a $200K decision made on data, not gut feel.
Someone has to find the margin before the plant commits. That someone is always Dave.
When Dave retires, his comparison table and scoping rationale are on record. The next engineer starts from Dave's analysis, not from scratch.
Weโre up to 27 ๐ก๐จ๐ฎ๐ซ๐ฌ ๐๐ซ๐๐๐. That's more PTO than Dave took all of 2025.
Dave left at 2pm. ๐๐ก๐๐ญ ๐ฐ๐๐ฌ ๐๐๐ซ๐ฅ๐ฒ ๐๐ง๐จ๐ฎ๐ ๐ก ๐ญ๐จ ๐ ๐๐ญ ๐จ๐ฎ๐ญ ๐จ๐ง ๐ญ๐ก๐ ๐ฅ๐๐ค๐.
