[ RFOD_016; RxMode   ; Rx Mode: Defueled; (Rx Mode data missing on NRC EN) ]

[ Rx Mode info missing in EN status box for this EN only. Body of EN contains RX Mode info : Defueled ]


"At 2200 EDT on September 11, 2018,
during inspections as part of the pressurizer bare metal inspection program,
an apparent weld defect was identified on Class 1 pressurizer level piping at the piping to pressurizer interface.

The reactor is currently defueled in a refueling outage.

Appropriate repairs will be made during the refueling outage."

NRC Resident Inspector has been notified.

[ Unclear if the weld defect was a pre-existing condition or if it was created during RFO repairs. ]

----------- [ Current event for MN_Monticello_1 ]

20180911 | MN_Monticello_1 | UNANALYZED CONDITION |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53597

"On 9/10/2018, the 11 [ pronounced One One ] Core Spray (CSP) loop was placed in service to support quarterly surveillance testing.

 With the 11 CSP pump in service it was identified that the check valves isolating the 11 CSP system from the keep fill supply were leaking by.

At 1129 CDT on 9/11/2018,

it was identified that this leakage may have exceeded the leakage rate assumptions made in the dose analysis calculation
for emergency core cooling system (ECCS) leakage outside containment following a loss of coolant accident (LOCA).

Therefore, this is being reported in accordance with 10 CFR 50.72(b)(3)(ii)(B) for an unanalyzed condition that significantly degrades plant safety
and 10 CFR 50.72(b)(3)(v) for any event or condition that at the time of discovery could have prevented the fulfillment
of the safety function of structures or systems that are needed to: © Control the release of radioactive material; or (D) Mitigate the consequences of an accident.

"The potential ECCS leak pathway has been isolated.
[ It wasn't 'potential', it was leaking. ]

There is no impact to health and safety of the public.
[ Even tho' it was outside containment ? ]

"The NRC Resident Inspector has been notified."

[ Notice there's no value as to amount of leakage or the radioactivity level. ]

----------- [ Current event for PA_PeachBttom_2;3 ]

20180911 | PA_PeachBttom_2;3 | TECHNICAL SUPPORT CENTER VENTILATION NON-FUNCTIONAL |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53594

"On September 11, 2018 the Technical Support Center (TSC) ventilation was discovered to be non-functional during system testing.

At 1310 EDT, an air leak was identified that prevented the modulating dampers to operate as designed to maintain required pressure. The air leak was not able to be repaired within a 60 minute period.

This failure affected the ability of the TSC ventilation system to maintain adequate radiological habitability in the event of an emergency with an airborne radiological release.

All other capabilities of the TSC are unaffected by this emergent condition.

The air leak has been repaired and post maintenance testing was completed satisfactory at 1654 [EDT], restoring the TSC ventilation to a functional condition.

"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to the potential loss of an emergency responsefacility because of the unavailability of the ventilation system."

The NRC Resident Inspector has been notified.

----------- [ Current event for TN_WattsBar_1 ]

20180911 | TN_WattsBar_1 | CONTROL ROOM EMERGENCY VENTILATION SYSTEM INOPERABLE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53593

"At 0113 EDT on September 11, 2018,
it was discovered both trains of CREVS [control room emergency ventilation system] were simultaneously inoperable;
therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v).

"There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."

The door to the main control room habitability zone from the turbine building was left open and unattended for about a minute,
breaking the pressure boundary in the room, resulting in an alarm.

The door was closed, clearing the alarm and the CREVS was considered operable.
