MARLA uses a Greedy algorithm coupled with Taboo search to design an in-core fuel shuffle that minimizes bridge motion while maximizing safety margin and reducing calculation time. MARLA performs in a few minutes what is otherwise an overnight calculation. MARLA also provides automation to design a full core off-load in lieu of an in-core shuffle. Automated licensing-grade shutdown margin calculation at each step. No working knowledge of SIMULATE required.
Maintenance Work Planning
Staging the core for maintenance work is performed automatically by MARLA’s optimization algorithm.
For BWRs, a single, interactive maintenance canvas allows the user to specify tasks such as:
- Control blade replacement
- Detector replacement
- Assembly inspection, sipping, or rechanneling
- In-vessel visual inspection work
