Plant Reactor Safety Design

What are the two Emergency Planning Zones ?

Site has quality employees who are trained and work conscientiously describes what?

Commercial Nuclear Industry Oversight: Who oversees internally?

A safeguard type cornerstone protection is considered what?

Safety limit Vogtle 1/2 of RCS pressure

Which are some of the mitigating systems of the reactor safety cornerstone?

We have to enter this when we can't do what we told the NRC we could do as a minumum to safely operate the plant.

Areas that could become high radiation areas during an accident.

Any loss of core geometry, particularly into a configuration where cooling becomes impractical is called what?

Redundant, independent, and diverse describes what ?

Emergency Classification Levels in order of severity

Examples of some Limiting Faults type DBAs

“Highest tier limit placed upon important process variables that are necessary to reasonably protect the integrity of physical barriers that guard against the uncontrolled release of radioactivity to the public.” ?10 CFR 50.36

This limit is protected by a reactor trip on high OT Delta T

A design philosophy using multiple redundant, independent, and diverse layers of defense to compensate for potential human or mechanical failures so that no single layer, no matter how robust, is exclusively relied upon.

Limiting Condition for Operation (LCO) describes what?

The following is a list of some things NRC measures as part of it's mission:

The Assessment level where performance indicates related cornerstone objectives are being met, but with a minimal reduction in the safety margin.

This limit is protected by a reactor trip on high OP Delta T

Site has a effective program to identify and fix problems. What is this program called?

Safety limit Vogtle 1/2 of containment pressure

Step Load Changes (up to 10%), heatup & cooldown, etc. describe what type of DBA's?

Emergency Classification Level where actual or potential substantial degradation of the level of safety of the plant exists. Lowest level at which the Technical Support Center (TSC) will be staffed. Exa: confirmed fire in a Safe Shutdown Building, where plant personnel reported visible damage to the building or the equipment contained within it.

Emergency Classification Level where actual or likely major failures of plant functions needed for protection of the public occurs.A DBA-LOCA is an example. Lowest level at which a site assembly and accountability of site personnel and relocation of non-essential personnel. All agencies activated: TSC, OSC, and ERF

The Assessment level where performance meets level where the associated cornerstone objectives are fully met.

No single failure of a safety feature results in the? loss of a protective function describes which aspect of "defense in depth"?

Which list best represents Cross-Cutting Areas of the Reactor Oversight Framework ?

What describes what the site has that is an effective program to identify and fix problems?

What are 2 Site Emergency Plan Goals?

Physically and Electrically separate describes which aspect of "defense in depth"?

Safety limit Vogtle 1/2 of fuel cladding Departure from Nucleate Boiling Ratio (DNBR).

Emergency Classification Level where actual or imminent substantial core degradation or melting with potential for loss of containment integrity can occur. Releases reasonably expected to exceed EPA Protective Action Guideline exposure levels off-site beyond the immediate site area. Transition to SAMG's & Burke Co.

Core exit thermocouple temperatures are greater than 1200°F and actions to cool the core are not successful. Which type of emergency classification needs to be declared?

Different methods utilized to accomplish the same? function describes which aspect of "defense in depth"?

Minor steam system piping failure, Complete loss of forced reactor coolant flow, Rod cluster control assembly misalignment, Small break LOCA describe what type of faults?

The Assessment level where performance is outside an expected range of nominal performance but related cornerstone objectives are still being met.

Which cross cutting area has the characteristic of minimizing or limiting mistakes made?

The set of accidents for which the designer makes explicit provision while remembering that more severe or peculiar accidents can occur, and ensuring that the design has some capability to deal with them.

What comes under the cornerstone of physical protection type safeguard?

What is the definition of the cornerstone type of reactor safety known as "initiating events"?

The Assessment level where performance indicates cornerstone objectives exhibit a significant reduction in safety margin in the area measured.

Personnel are comfortable raising concerns about nuclear safety describes what?

Which organization provides specifically the following services: ?

Evaluation & Assistance
Event Analysis and Information Exchange
Training and Accreditation

To ensure adequate protection of public health and safety in the peaceful uses of nuclear materials, including nuclear power plants is a goal/mission of which organization?

Which list describes the various Fission Product Barriers ?

Describes the type of NRC inspection where a team of outside NRC personnel come in for more serious plant issues.

Safety limit Vogtle 1/2 of fuel pellets (temperature)

Personnel are comfortable raising concerns about nuclear safety describes which cross cutting area of nuclear awareness?

Which of the following is not a corrrect list of Cornerstones of Safe Plant Operation ?

Emergency Classification Level where no releases of radioactive material requiring off-site response or monitoring.
