  1. Unit Two reactor pressure instrument B21-PT-N023A has been declared inoperable and has been placed in the tripped condition to comply with LCO 3.3.1.1. Consider the following reasons it may be desired to remove the instrument from the tripped condition:

    1. For a PMTR to demonstrate the instrument has been repaired and is operable
    2. For additional troubleshooting to determine the cause of the instrument failure
    3. To allow surveillance testing of other RPS channel A instruments
    4. To allow surveillance testing of RPS channel B instruments

    Which of the above is permitted by Technical Specifications?
    A. 1 only.
    B. 1 and 2 only.
    C. 1, 3, and 4 only.
    D. All four are permitted.
    C. 1, 3, and 4 only.


    LCO 3.0.5 bases
  2. Unit Two Reactor Water Level trip units B21-LTM-N024A-1-1 (Low Level 2) and B21-LTS-N024A-1-2 (Low Level 3) are being placed in an inoperable status to perform SR 3.3.6.1.2 and SR 3.3.6.1.3. All other instrumentation is Operable.

    Which of the following is correct per Technical Specifications?


    A. Entry into LCO 3.3.6.1 Condition A may be delayed for up to 2 hours to perform the surveillance testing.
    B. Entry into LCO 3.3.6.1 Condition A may be delayed for up to 6 hours to perform the surveillance testing.
    C. LCO 3.3.6.1 Condition A must be entered immediately, the channels must be placed in trip within 12 hours.
    D. LCO 3.3.6.1 Condition A must be entered immediately, the channels must be placed in trip within 24 hours.
    B. Entry into LCO 3.3.6.1 Condition A may be delayed for up to 6 hours to perform the surveillance testing.
  3. Unit Two is in Mode 1 with SBGT Fan 2A under clearance for the past 12 hours. The
    required actions of LCO 3.6.4.3 Condition A have been entered. 480 VAC Substation E8 trips on fault.

    What is the status of Secondary Containment Operability in accordance with Technical Specifications? Secondary Containment is:

    A. Operable, SBGT does not support Secondary Containment Operability.
    B. Inoperable, and actions of LCO 3.6.4.1 are required to be entered per LCO 3.0.6.
    C. Inoperable, but actions of LCO 3.6.4.1 are not required to be entered per LCO 3.0.6.
    D. Operable, SBGT does support Secondary Containment Operability, but Secondary Containment is still Operable per LCO 3.0.6.
    B. Inoperable, and actions of LCO 3.6.4.1 are required to be entered per LCO 3.0.6.


    E8 is inoperable (LCO 3.8.7). Per LCO, 3.0.6 equipment that is inoperable solely because E8 is inoperable is inoperable, but cascading into actions of supported systems is not required by LCO 3.0.6, provided a loss of safety function (LOSF) does not exist. Since both SBGT trains are inop, this consists of a LOSF and requires entry into actions of LCO 3.6.4.3 for both SBGT. Since both SBGTs are inoperable, this is also LOSF for secondary containment and actions of LCO 3.6.4.1 are also required.
  4. Engineering has written as A/R for Unit 2 stating that the GM detector for 2-D12-N010A, Reactor Building Vent Radiation Monitor, may not function as designed due to age related degradation. A review of other documentation reveals 2-D12-N010B was recently replaced and is not a condern. This information was presented to you at 0800 on 9/04/2003.

    Based on this information, the required actions per Tech Specs are:

    A. Place channel in the tripped condition no later than 0800 tomorrow (9/05).
    B. Place channel in the tripped condition no later than 2000 today (9/04).
    C. Restore isolation capability no later than 0900 today (9/04).
    D. Immediately isolate the affected penetration.
    A. Place channel in the tripped condition no later than 0800 tomorrow (9/05).
  5. Unit 2 is conducting a plant startup per 0GP-02. 0PT-11.1.2, “AUTOMATIC DEPRESSURIZATION SYSTEM AND SAFETY RELIEF FALVE OPERABILITY TEST,” is in progress. The following conditions exist:

    - Suppression Pool water temperature is 86°F and rising.
    - Both loops of Suppression Pool cooling are in service.

    While performing the test, SRV “K” control switch fails causing the valve to remain open for an extended period of time. The operator pulled the AOP-30 fuses and the valve was verified closed.

    No heat addition to the Suppression Pool is occurring. The Suppression Chamber temperature is now 112°F and lowering.

    In accordance with Unit 2 Technical Specifications, which ONE of the following actions is required?


    A. Manually Scram the reactor AND depressurize the reactor vessel to less than 200 psig within 12 hour.
    B. Manually Scram the reactor AND verify Suppression Pool temperature is < 120°F once per 30 minutes AND be in MODE 4 in 36 hours.
    C. Commence reactor shutdown per GP-05 within 1 hour AND reduce thermal power to range 7 on IRM’s within 12 hours AND maximize suppression pool cooling.
    D. Suspend all testing that adds heat to the Suppression Pool AND verify supression pool temperature is <120°F once per 30 minutes AND maximize suppression pool cooling.

    References: Tech Specs 3.6.2.1, Suppression Pool Average Temperature
