20181206 | MN_PrairiesIsland_1 | [ Notice Date] PART-21 - RHR SHAFT SEAL O-RING SHEARED DUE TO MANUFACTURER DEFECT |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53780
RFOD_018;

The following is a synopsis from the Part 21 report received via e-mail:

During an outage at Prairie Island Nuclear Generating Plant,
[ records show that PI unit 1 was in RFO and was the only PI unit in outage. ]

the licensee replaced the mechanical shaft seal on the 11 Residual Heat Removal (RHR) pump.
During subsequent post maintenance testing, it was found that there was significant seal leakage on the pump.

An evaluation was completed on December 4, 2018, which determined that it was a substantial safety hazard.

The licensee has shipped back six seals to Framatome to be tested.
It was determined that the cause of the failure was improper O-ring installation by the manufacturer.
Discussions with Framatome indicate that only Prairie Island Nuclear Generating Plant is effected by this defect,
but investigations are still ongoing.

Affected Plant:
Region 3: Prairie Island Nuclear Generating Plant

Licensee: FRAMATOME INC
City: LYNCHBURG   State: VA

[
Framatome used to be Areva NP ( Areva falsified tests iirc ) went bankrupt.
owned by Électricité de France (75.5%), Mitsubishi Heavy Industries (19.5%), and Assystem (5%).
New name, same incompetence.
HHD has posted numerous items regarding the nuclear corruption surrounding this and other companies involved in nuclear industry.
Areva was renamed Orono.
