SRO Exam # 25 417 Question is technically correct. Students that missed this question did not take into account the EAL declaration that needed to be made due to changing plant parameters. Review with class. No program deficiency noted.
SRO Exam Question #6 Columbia experienced a LOCA. When the Reactor was manually scrammed, all rods did not go in.
Reactor power is 2% and steady, Drywell Pressure is 12 psig and trending up slow and Suppression Pool temperature is 85°F and steady. The Shift Manager declares a Site Area Emergency.
Which of the following prompts the Shift Manager to declare a Site Area Emergency and what actions should the CRS direct?
A. Suppression Pool Level indicates 19 ft. 1 inch. Direct HPCS initiation per PPM 5.5.23.
- d. Wetwell Pressure indicates 12 psig. Direct Drywell sprays be initiated per PPM 5.2.1.
C. RPV/L indicates -181. Enter PPM 5.1.5 and direct an Emergency Depressurization.
D. An ATWS exists. Enter PPM 5.1.2 and direct PPM 5.5.10 and PPM 5.5.11 to insert rods.
ANSWER: B
REFERENCE:
PPM 13.1.1 block3.1.S.l; PPM 5.2.1 JUSTIFICATION: The SAE is declared due to 3.1 .S.1 - Drywell pressure response not consistent with LOCA conditions as WW and DW pressures are almost equal. Normal dP is 5 psig. A is incorrect as a UE would be declared. C is incorrect as RPV/L would need to be -183 for SAE. D is incorrect as all the conditions for 2.2.S.1 are not met.
The stem gives parameters that indicate that Primary Containment is broken and drywell pressure GT 12 psig which requires drywell sprays be initiated. D is the correct answer per the exam key and is correct.
Choice A is also a correct answer. If you look at the stem and plot the parameters given on the PSP curve, you end up in the unsafe region of PSP therefore PSP has been exceeded. Based on exceeding PSP with drywell pressure GT 1.68 psig, with indication of RCS leakage inside drywell, a Site Area Emergency should be declared per EAL 3.2.S.2. Additionally, with Wetwell Level LT -2 inches, PPM 5.2.1 directs HPCS be used to refill the wetwell per PPM 5.5.23. This makes choice A also a correct answer.
Choice A was originally indicated to be incorrect based upon Wetwell Level not able to be maintained above 19 2 which, if you look at block L-7 for PPM 5.2.1 Primary Containment Control, indicates that a UE should be declared.
Columbia is requesting dual credit for answers Aand B for this question.

SRO Exam Question # I 8 The plant is operating at 100% power. B RHR was declared inoperable yesterday at 0800 because of a ground on RHR-P-2Bs motor. During an A RHR Operability test, RHR-V4A, Suppression Pool suction valve, was closed, tripped on electrical overload mid-stroke, and was subsequently declared inoperable at 1200 today. Then at 1800 today, B RHR was declared operable.
Based on the above information, Columbia must be in MODE 3 no later than ...
A. 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from 2000 today.
B. 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from 0200 tomorrow.
C. 7 days plus 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from 0800 yesterday.
D. 7 days plus 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from 1200 today.
ANSWER: D
REFERENCE:
TS 3.6.1.5-1; TS 3.6.1.3-1 & -2; TS 3.5.1-1, -2 & -3; TS 3.6.2.3-1 JUSTIFICATION: At 0800 yesterday a 7 day clock started. At 1200 today the 7 day clock became a 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> clock (2 spray systems 00s).At 1800 the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> clock stopped and again became a 7 day clock but clock is started from first RHR system failure (B RHR ground) and not A RHR (RHR-V-4A failure). A is incorrect as it is for 2 trains 00s from 1200 today; B is incorrect as it is todays time (1800) plus 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. C is incorrect as it is 7 days from the first RHR failure and does not take into account that the completion times may be extended per TS section 1.3. D is correct.
The stem states that RHR-B went hop yesterday at 0800, RHR-A went inop at 1200 today and then RHR-B was declared operable at 1800 today. Technical Specifications 1.3 (Completion Times) states that when a second division is discovered to be inop the completion time may be extended; and then it gives criteria necessary to extend the time.
The stem includes those conditions to extend the completion time. Technical Specifications then states that 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> may be added to the initial entry into the condition.
If you add the extension onto the initial entry, Columbia must be in Mode 3 no later than 7 days (per TS 3.1.6.5), plus 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (extension per TS 1.3) plus 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (completion time to be in Mode 3 given by TS 3.6.1 5)from 0800 yesterday.
If you take the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> extension the completion time is 7 days plus 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, plus 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from 0800 yesterday. Choice ID the original answer, is actually 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> too long which makes it an incorrect answer. Choice C is the correct answer as it is 7 days plus 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from the initial entry into the condition.

SRO Exam Question #20 During the fuel shuffle in a refueling outage, as the Refueling Floor Supervisor, you observe a fuel bundle that doesnt seem to have the correct orientation. You review the NCTL and note the fuel bundles orientation is 180 degrees different from what the NCTL requires.
Which of the following is correct concerning this situation?
A. This is not considered to be a fuel loading error nor is it considered to be a reactivity event. The Refuel Floor Supervisor has the authority to correctly orientate the fuel bundle and will document the move on the NCTL.
B. This is considered to be a fuel loading error. The Refuel Floor Supervisor will correctly orientate the fuel bundle and document the move on the NCTL.
C. This is not considered to be a fuel loading error. This is considered to be a reactivity event which should be brought to managements attention.
D. This is considered to be a fuel loading error. The Reactivity Manager and the Shift Manager will determine how to resolve the error and must give permission to recommence the fuel shuffle.
ANSWER: C/)
REFERENCE:
PPM 6.3.2 Precaution and Limitation 5.25 page 15 JUSTlFICATION: Per PPM 6.3.2, the SM and Reactivity Manager are notified and will resolve error and give permission to recommence core alts (C is correct). The RFO does not have authority to resolve error alone (A is incorrect). Neither the CRS nor the Reactivity Manager alone gives permission to restart core alts (B and D are incorrect).
The question is written on the premise that the fuel bundle that the stem references as being mis-positioned, was moved during the current fuel shuffle. Under this premise, C is the correct answer.
The stem does not specifically state that the fuel bundle had been moved during this fuel shuffle.
Per SWP-ME-01 6.4, one of the definitions of a Fuel Loading error is A fuel bundle orientation in the reactor core is other than specified in the NCTL and not corrected prior to criticality.
If you take the premise that the fuel bundle was not moved during this fuel shuffle and was mis-orientated during the previous fuel shuffle and not corrected prior to criticality, than the event would be classified as a Fuel Loading Error which would lead to D being a correct answer.
Columbia is requesting dual credit be given for answers C and D for this question.

Fuel Loadinn Errox A fuel loading error is defined as any of the following actions:
8 Inserting a fuel bundle in an incorrect location in the Reactor Cor. This point is reached when the nose piece of the bundle is inserted past the bottom of the Top Guide Core Structure in a location other than what is specified in the NCTL.
8 A fuel bundle orientation in the reactor core that is other than specified in the NCTL and nQl corrected prior to criticality. Any misorientation(s)should be reported to the Reactivity Manager as they are identified.
NOTE: Seating a fuel bundle in the SFP in a location or orientation other than specified in the NCTL is 9pt a fuel loading error.
6.5 Core Alt Suwrvisor (MAE) - The individual with the primary responsibility to supervise refuel activities involving core alterations. The position requires an SRO license per FSAR and 10CFR50.54.
6.6 SDent Fuel Pool Suwrvisor (RFAF) - The individual with the primary responsibility to supervise activities taking place in the Spent Fuel Pool, in other than mode 5, including movement of new fuel, spent fuel and other operations. This position does not require a NRC license.
