Implementation of New MPI

Cycles that ended in 2014 and some cycles that ended in

early 2015 used the old MPI.

Other plants/cycles are handled on a case by case basis.

Options:

Back fit data to revised MPI

Use both current/revised MPI

– No plants in the database file are using a combined

MPI format

Templates using the revised MPI were provided for cycles

that started in late 2014 and beyond.

–37 of 44 plants have been transitioned in the CMA

database; expect full transition after overdue data are

received

HWC-M:

– Three plants are Yellow or Red

due to low HWC availability.

One plant had a short cycle (10

Observations related to MPI

Challenges to HWC availability included:

– Hydrogen supply availability in northeast U.S. in 2014

– Multiple trips due to flow control valve failure

– Mid-cycle outages

– Short cycle lengths

ECP Electrodes

– 38 of 45 plants have provided a status of working electrodes

Primarily located in MMS Skid

Hydrogen water chemistry benchmark tests

– 37 of 44 plants provided a status of their last benchmark test

Perry and Peach Bottom 2 recently performed benchmarks

Monticello benchmark planned for September 2016

Valid benchmark kept monthly MPI status “Green” at Susquehanna 1 after ECP probes failed

Most benchmarks have been performed within the last 5 years
