Limerick nuclear plant

[RichardKramer]

Are there any voice tx for the frequencies for the Limerick nuclear plant? I.m hearing a data signal on 461.475 DCS346 from Chester Co.
Anybody able to decode it? TIA!

Said data signal as documented in the RRDB. Don't believe there's much (if anything) to decode from CompuLert. But as long as the sirens understand it, we're good

I've sat in the neighboring Philly premium outlets lot in the past and scanned through these simplex frequencies. Never heard anything from them though. Not sure if the plant operates on the fully encrypted Exelon system or not but, I'm sure ops would be fully encrypted whether there or not...

LGS operates on the 500 (T-Band) splits. There primary antenna system is internal to the plant, which means that very little RF is eminated outdoors. They are P25 Phase 1 conventional. Yes the 461 frequency is for the EP siren system that transmitter is standalone at another site. Coatesville can also control the EP sirens in case of evac is necessary.

Any insight on which frequencies and NAC(s) are confirmed in use to get the info added to the RRDB? Encrypted or clear ops?

I retired from a Nuc plant. It's probably E. I think he NRC requires it, for details PART 73—PHYSICAL PROTECTION OF PLANTS AND MATERIALS | Nuclear Regulatory Commission

4w ERP repeaters. Low power for sure. Based upon what @X9009X said, you probably can't even get close enough to the plant to hear them lol.

Understood, I figured since he was in the know about their P25 usage that he'd have some more detailed "insider info"

Why would you pursue "insider info" about a security system at a nuclear power station?
