Palo Verde Nuclear Generating Station (PVNGS) Unit 2: Steam Generator Tube Inspection Report Attached please find the PVNGS Unit 2 Steam Generator Tube - October 10, 2014

This report is intended to satisfy the requirements of PVNGS Technical Specifications 5.6.8 for


By Bob Meyer

This inspection report contains an excellent analysis of a violation that many plants easily slip into. The longstanding uncorrected and uncompensated nonconforming condition was a result of the station personnel failing to use decsion-making practices that emphasized prudent choices over those that were simply allowable, (pencil-whipping).

Green. The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, “Corrective Action,” in that the licensee did not enter degraded conditions into the corrective action process. The first example of this violation occurred in ten identified instances from 2009 to 2012 when technicians failed to document degraded emergency diesel generator fuel injector nozzles in the corrective action program. The second example occurred in July and August 2014 when engineering personnel failed to appropriately document loose bolts on 4.16kV breaker panels in the corrective action program.

The inspectors determined this finding has an identification cross-cutting aspect in the problem identification and resolution cross-cutting area because the organization failed to implement a corrective action program with a low threshold for identification (P.1). Specifically, personnel failed to recognize that identified deficiencies were deviations from standards and that degraded conditions were promptly documented in the corrective action program. 


On September 25, 2014, the NRC completed an inspection at your South Texas Project Electric Generating Station, Units 1 and 2.

Green. The team identified a non-cited violation of Technical Specification 6.8.1.d for the failure to implement and maintain written procedures for fire protection program implementation. Specifically, the licensee failed to have procedures for and to flow test the portions of the underground piping that supplied water to the diesel generator buildings since the initial startup test. The licensee initiated actions to perform the flow testing within two months and entered the deficiency into their corrective action program as Condition Report 14-17098. 

NRC claims Entergy submits inaccurate information

BRATTLEBORO — Federal regulators are not satisfied with Entergy Nuclear’s claims that emergency planning can be reduced once Vermont Yankee shuts down.

A lengthy letter from the Nuclear Regulatory Commission to Entergy Nuclear is punctuated with three complaints that the company’s filing was “inaccurate.”

In all, the NRC staff made 35 detailed requests for additional information from Entergy to justify its request, with the NRC staff raising questions about public safety at the plant under some scenarios until all the high-level radioactive fuel has been put into long-term storage.

“The NRC staff has determined that additional information is required to facilitate our further technical review and to ensure that the staff can reach a reasonable assurance finding,” read the letter, dated Monday.

The NRC staff said Entergy was “inaccurate” when it claimed that there were no accidents “that would result in dose consequences that are large enough to require off-site emergency planning.”

And the staff also said Entergy “inaccurately” stated the analysis of the potential radiological impact of an accident once the plant’s fuel is removed from the reactor core, or “defueled.”

The Shumlin administration has so far opposed the reduction of emergency planning for the area towns, until some emergency milestones are reached.

Public hearing: Nuke plant expansion would bring jobs, risks

071411-HOPE CREEK-GE.jpg_20110720.jpgA public comment session in Middletown about a site for a possible new PSEG nuclear reactor along the Delaware River quickly turned into a series of statements for and against nuclear power Thursday, despite the session's official focus only on where, and not what or when.

The Nuclear Regulatory Commission's draft environmental impact review, one of two for the day, was the first of its type in Delaware. It was hastily arranged after the state's congressional delegation noted that regulators took testimony only in New Jersey on the company's bid for a reactor site approval good for 20 years.

About 33,000 of the more than 45,000 residents within the existing Salem/Hope Creek nuclear complex's 10-mile evacuation zone live in Delaware, based on the 2010 Census. Growth surely has pushed the number higher since.

Operational Event Notification Report for October 24, 2014



The purpose of this notification is to retract the ENS notification made on September 4, 2014 (ENS 50427). Upon further investigation it was verified that the function of Control Room Emergency Ventilation System was not affected as discussed in Chapters 6 and 15 of the Updated Final Safety Analysis Report. Therefore, the threshold for reporting the issue as an event or condition that could have prevented the fulfillment of a safety function was not met (NUREG 1022 Revision 3 - Event Report Guidelines Section 3.2.7).


At 0107 CDT on October 23rd, 2014, both doors in one of the Secondary Containment airlocks were momentarily open concurrently. This occurred during vessel drain down following refueling activities, an Operation with the Potential to Drain the Reactor Vessel (OPDRV), which required Secondary Containment to be operable. The doors being open at the same time resulted in the momentary inoperability of Secondary Containment. One of the doors was immediately closed, and Secondary Containment was restored to an operable status.

"The station [Duane Arnold] has now completed the OPDRV associated with vessel drain down, and Secondary Containment is no longer required to be operable. 

NRC Renews License for Dry Spent Fuel Storage Facility at Calvert Cliffs

The Nuclear Regulatory Commission has approved a 40-year license renewal for Exelon Generation’s dry-cask independent spent fuel storage installation at the Calvert Cliffs nuclear power plant in Lusby, Md.

The license now has an expiration date of Nov. 30, 2052. The initial 20-year license would have expired Nov. 30, 2012, but Exelon submitted a request to renew it in 2010. This meant the facility was considered to be in “timely renewal,” where the license would not expire as long as the NRC staff was reviewing the request. This allowed the Calvert Cliffs’ independent spent fuel storage installation to continue to operate under its existing license until the NRC completed its safety and security review and reached a decision on the license renewal application.

The renewed license, the fifth the NRC has issued for a dry cask storage facility, contains conditions requiring periodic inspections of the casks and their components to ensure potential aging effects are identified and managed. These conditions require Exelon to take corrective action to address findings that could prevent a cask component from performing its safety function.

NRC Issues Security-related Inspection Finding for Limerick Nuclear Plant, Resulting in Increase in Agency’s Oversight at Facility

The Nuclear Regulatory Commission will increase its level of oversight at the Limerick nuclear power plant following the finalization of a security-related inspection finding that has been classified as “greater than green.” The twin-reactor plant is located in Limerick (Montgomery County), Pa., and is operated by Exelon.

The NRC uses a color-coded assessment system for inspection findings and performance indicators. The colors range from “green,” for very low safety or security significance, to “white,” “yellow” or “red,” for high safety or security significance. In the case of security-related inspection findings or performance indicators, the NRC notifies the public when the “greater than green” threshold has been crossed. However, the agency does not provide specifics because of the sensitivity associated with such findings and indicators.

During an inspection conducted at the Limerick plant from June 16 to 20, the NRC documented the finding. Per the NRC’s review process, Exelon was offered an opportunity to provide a written response or take part in a Regulatory Conference with NRC staff to provide additional information and/or perspectives regarding the finding. Exelon chose to take part in a conference, which was held on Sept. 18.

After considering the information presented by the company, and the information developed during the inspection, the NRC has determined the finding is appropriately characterized as “greater than green.”

Fusion reactor: The countdown has begun

Although it is difficult to plan our energy future based on these claims, a commercial fusion reactor - whether hot or cold - no longer looks like a pipedream. There would be one within the lifetimes of many readers, and probably within the lifetimes of most people in the world. The real question is this: will they be good enough to change the world? 

Predictions are not always easy in technology, but here are a few thoughts.

have a black MC cl??s and have experienced no problems with chipping, etc - but I don't use it on a daily basis. I would think that for a daily wallet that's going to get a lot of use, one of the other canvases might be a better choice in the long run. I don't think Vernis would be affected by use in a warm climate, though - as someone else said, when they say it shouldn't be left in the heat they mean i louis vuitton purse
