LC32 Admin Week One - Tech Specs & TRM

Question 1

Tech Spec Criterion #1

Answer 1

Instrumentation used to detect and indicate in the control room the degradation of the Reactor Coolant System pressure boundary.

Question 2

Tech Spec Criterion #2

Answer 2

Process parameter, design feature, or operating restriction that is the initial condition of a design basis accident which presents a challenge to fission product barriers.

Question 3

Tech Spec Criterion #3

Answer 3

SSC that is a part of the primary success path which functions or actuates to mitigate a design basis accident.

Question 4

Tech Spec Criterion #4

Answer 4

SSC which OE or PRA has shown to be significant to public health and safety (whatever the NRC describes as important).

Question 5

Define Identified Leakage and the Administrative Limits.

Answer 5

Identified leakage is:
- Any leakage that is collected in and processed by a sump or collection tank
- Any leakage into the containment atmosphere that does not interfere with appropriate operation.
- Primary to secondary leakage in a steam generator

Admin Limits:
- 10 GPM total identified leakage
- No greater than 150 GPD in any SINGLE generator

Question 6

Define Unidentified Leakage and the Administrative Limits

Answer 6

Any leakage that is not identified

Admin Limits:
- 1 GPM total unidentified leakage

Question 7

Define Pressure Boundary Leakage

Answer 7

Any leakage through a non-isolable fault in an RCS component body, piping, or wall.

Question 8

Define Operability

Answer 8

The SSC and all of its supporting systems are operable.

Question 9

Describe each mode and the GENERAL criteria for entering each mode

Answer 9

Mode 1 - Critical and Greater than 5% Power
Mode 2 - Critical and Less than 5% power
Mode 3 - Sub critical and GREATER than or EQUAL to 350F
Mode 4 - Subcritical and Less than 350F and Greater than 200F
Mode 5 - Subcritical and Less than 200F
Mode 6 - One head-stud de-tensioned

Question 10

Describe the REACTOR CORE SLs, applicability, and associated actions

Answer 10

In Modes 1 & 2 - DNBR GREATER than or EQUAL to 95/95

In Modes 1 & 2 - Fuel pellet center-line temperature Less than 4700 Deg F (5080 on U2).

ACTION:
Be in Mode 3 within 1 hour.

Question 11

Describe the RCS PRESSURE SLs, applicability, and associated actions

Answer 11

In Modes 1-5 - RCS Pressure Less than 2735

ACTION:
If in Modes 1 or 2 - Be in mode 3 within 1 hour

If in Modes 3-5, restore compliance within 5 minutes and do NOT change mode

Question 12

Describe LCO 3.0.1

Answer 12

LCOs shall be met while in the MODES in which the LCO is applicable.

Question 13

Describe LCO 3.0.2

Answer 13

Upon discovery of the inability to meet the LCO requirement outlined by LCO 3.0.1, required actions shall be met.

Question 14

Describe LCO 3.0.3

Answer 14

If it is determined that the action statement in an LCO is unable to be met within the allotted time, OR if there is no action statement for the condition that the plant is in, enter LCO 3.0.3.

ACTION:
Be in Mode 3 in 7 hours
Be in Mode 4 in 13 hours
Be in Mode 5 in 37 hours

Question 15

Describe LCO 3.0.4 and relevant subsections

Answer 15

When an LCO is not met, entry into another mode is not permitted unless:

3.0.4a - The associated actions to be entered permit continued operation in that mode indefinitely

3.0.4b - A risk assessment is performed

3.0.4c - When an allowance is stated in the individual value, parameter, or other specification.

Basically, mode changes cannot be performed for the operational convenience of making an LCO no longer applicable. If an LCO is required in Mode 4, but no longer required in Mode 3, a Mode change to 3 cannot happen until the Mode 4 LCO is met.

Question 16

Describe LCO 3.0.5

Answer 16

Allows the return of SSCs to service for testing purposes. NO preventative or corrective maintenance is allowed during this time.

Question 17

Describe LCO 3.0.6

Answer 17

Allows for a supported system to not be determined inoperable solely because a supporting system inoperable.

Question 18

Describe LCO 3.0.7

Answer 18

Allows suspending applicable LCOs for physics testing.

Question 19

Describe SR 3.01

Answer 19

Surveillances applicable to an applicable LCO must be met

Question 20

Describe SR 3.0.2

Answer 20

The frequency of a surveillance is met if it is performed within 1.25x the frequency (e.g. ‘Once per 8 hours’ = 10 hours). This does NOT apply to the first time the surveillance is performed (i.e the first performance must be within the 8 hour window).

Question 21

Describe SR 3.0.3

Answer 21

Allows an additional 24 hours or the limit of the specified frequency to complete a missed surveillance, whichever is GREATER.

Question 22

Describe SR 3.0.4

Answer 22

A mode change to a HIGHER mode cannot take place until the required preliminary surveillances for that mode are completed unless otherwise specified in LCO 3.04

Question 23

How are Technical Specifications defined and who approves revisions?

Answer 23

Technical Specifications are license-based documents and revisions are approved only by the NRC.

Question 24

How is the Technical Review Manual defined and who approves revisions?

Answer 24

The Technical Review manual is a license-based document and revisions are approved by the Plant Manager.

Revisions are sent to the NRC in 18-month intervals.

Question 25

Describe the Three types of TR LCOs

Answer 25

Full - SSC requirements for the associated applicability exist solely in the TRM Partial - A portion of the SSC requirements exist in the TRM and additional requirements can be found in the TS. Supporting - A TR LCO that supports requirements for a TS LCO.
