“Capability is a depleting resource to be spent, not a fixed budget to be defended.”

Whitepaper, §5

Monitoring computers in nuclear facilities work where access is limited and parts age under radiation. They need to keep reporting as they degrade.

Mru Field runs on the processors already in the equipment. When one fails and nobody can come, it continues on the ones left and delivers only results it can check. Status: decision core at TRL 3; first field pilot planned for 2027.

01

## Computers fail one by one

Radiation, heat and age take out processors and memory. Nothing is replaced until the next visit.

02

## Stored data decays

Flash wears out and bits flip. Logs and settings drift unless something checks them.

03

## No one to ask

When two computers disagree, there is no operator to say which one is right.

## Three computers. Then two. Then one, still working.

Most redundant systems stop when they lose their majority. Mru Field steps down instead, and says which mode it is in.

Three computers vote. One bad result is outvoted.

2 alive · compare

A B C

Two compare. A known-answer test finds the faulty one.

1 alive · self-check

A B C

The last one checks its own work and keeps reporting, at half speed.

## Questions

Does Mru Field need new hardware?

No. It is software for the processors you already deploy. It runs beside your control code and decides which computer to trust as parts fail.

Is Mru Field safety-certified?

Not today. It is for monitoring and non-safety control. Certification would come with a partner.

How do we start?

Use the form below. We first model your hardware and show what each redundancy design returns over its whole life. Then we plan a pilot on your own equipment.
