There are 4 EN(s) today, 1 associated with power stations.

[ NRC EN reporting still funky. These EN are nothing more than re-posts of yesterdays ENs. ]

20180619 | NJ_Salem_2 | Repost TORNADO MISSILE VULNERABILITIES |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53438


"During the period of evaluation of tornado missile vulnerabilities and the potential impacts to technical specification (TS) plant equipment,
it was determined that the power cables to a safety related motor control center (MCC) in the service water (SW) intake structureare not adequately protected from tornado generated missiles.

During walk downs, it was identified that the installed SW pipe tunnel barrier is not adequate.
A tornado could generate missiles capable of striking the power cables and rendering a SW MCC inoperable.

"These conditions are reportable per 10 CFR 50.72(b)(3)(ii)(B) and per 10 CFR 50.72(b)(3)(v)(D).

"This condition is being addressed in accordance with NRC enforcement guidance provided in Enforcement Guidance Memorandum (EGM) 15-002,
'Enforcement Discretion for Tornado-Generated Missile Protection Noncompliance,' Revision 1,
and DSS-ISG-2016-01, 'Clarification of Licensee Actions in Receipt of Enforcement Discretion per Enforcement Guidance Memorandum EGM 15-002,
Enforcement Discretion for Tornado- Generated Missile Protection Noncompliance,' Revision 1.

Compensatory measures have been implemented in accordance with these documents.

"The NRC Resident Inspector has been notified."

The licensee will be notifying the Lower Alloways Creek Township.


* * * UPDATE ON 6/18/2018 AT 1604 EDT FROM JUSTIN HARGRAVE TO RICHARD SMITH * * *

"During subsequent walk downs, PSEG [Public Service Enterprise Group] identified that both the Unit 1 and Unit 2 turbine driven auxiliary feedwater pumps are also not adequately protected from tornado generated missiles.

The steam exhaust pipe could be potentially impacted and cause crimping that could reduce steam exhaust flow and pump capacity.

EN 53438 is updated to include both Salem units and these additional components.

"This condition is being addressed in accordance with NRC enforcement guidance provided in enforcement Guidance Memorandum (EGM) 15-002,
'Enforcement Discretion for Tornado-Generated Missile Protection Noncompliance,' Revision 1,
and DSS-ISG-2016-01, 'Clarification of Licensee Actions in Receipt of Enforcement Discretion per Enforcement Guidance Memorandum EGM 15-002,
Enforcement Discretion for Tornado-Generated Missile Protection Noncompliance,' Revision 1.

Compensatory measures have been implemented in accordance with these documents."

The NRC Resident Inspector has been notified.

The licensee will be notifying the Lower Alloways Creek Township.

Notified R1DO (Burritt).
