Peach Bottom receivedtehe results -of ther sampling of.Geo-pr.be #4and the: results weregreater thanh20,00, Pico Curies of Tritium. ,(An m of cationof these. probes is attached), This.CAP document for this event is also attached-for information, Attaahedforinfortion is information from Monitoring Wells that Peach,.Bottomý has been sampling-weekly.

Currently, the highest sample result if from~ the Unit 3 yar~d drain sump.f This: l"c~ation is not shown on the map but is.located behind the Unitt*3 Reactor IBu!ilding and. inIthye vicinity of the Unit 3 CST. The next highest value (2900 p~Ci/L)is from monitoringIwell #4 (MW-PB-4.on the-'attached map).

In accordance with the Industry Ground Water Protection Initiative, Peach Bottom has determined that only "informal" and voluntariy notification of NRC and State officials by the end of the business day (today) is required. This meanis that a notiffication to the HOC is not required,. ~However, Peach Bottom is still developing their repotability communications plans. (Exqerpt of.. ExeIon Reportability Manual (LS-.*AA1 120) is Peach Bottom is considering a press relea*e on this issue. If a press releas/e is made, Peach Bottom will make a 50.724tOthhHef46r* th. press release.

FW: Potentially more tritiumdiscovered at,Peach'Bottom Neil, Diane, Nancy, Doug, FYI onisome.r indications of tritium at P.B. We'll have more info ,tomorrow. I've already engaged'DRS,.

Important points to note right now:

"nomiaatjon inthis recoruwas delsied in apcordance with the Freedom of bnbo~Maalo AcL

  • 1*ft

OOne testilocation had 122, 000 pCi/L tritium. A confirmatory sample has not been analyzed'yet.

Expect reult tomorrow.

No indications that there is an unmonitored release atfthis point. Outfall locations are LDA but any

, tritium would be very diluted at the outfall.

PB fouid this as part of an initiative they have been undertaking forthe last year. This started when PB found -4000 pCi/I in a well adjacent to the inner screen house,

  • PA and MIDbEPare being given courtesy notifications by PB, on this issue.

I have a site map with a!more precise location of the wells. More to.follow tomorrow.

Potentally more tritium discovered at Peach Bottom.

Pauletal, * *. *. .. . S

Bill ' aguire (Site VP) just stopped by and informed me, of some preliminary results for3 Geo-probes that were recently dug at Peach Bottomi.

For Geo-probe #2 the results were Less' than Detectable (LTD)

For.Geo-probe #3 the results were 122,748 pico Curies of Tritiunm.

~For Geo-probe #4the results were ,22,I100 pico Curies of 'Triti'umi Note - these are just preliminary results and they have sent the samples'out for Confirmatory samples., Bill did indicat* that he plans to give.RichJaanati and the State of Maryland a call just to alert them of'thbepotential

-results.*

He expects to have the confirmatory results for Geo-probe #41 back either tonightTor tomorrow~ and will make the official notifications at that time.**e also ndidicatedq that they planr to take samplesof,the Susquedhanna

.River? to ensure that they are nOt seeing anything there. Bill: indicated that,they'(PB) still feel ,that this ýcould be water from the, Unit a CST.

I have attached a picture showing Where. the samples were taken.
