.43y Explanation General Comments:
- 1. All Tier 1 questions must meet the objective of testing demonstrated knowledge and proficiency of how to safety operate the plant during emergency or abnormal conditions. Satisfactory ways of meeting this objective include, but are not limited to, the following:
(1) information contained in the sites procedures, including alarm response procedures, AOPs, EOPs, and their associated bases documents (2) diagnosis that leads to selection of the procedures that should be used to respond to the evolution (3) the progression of an event (4) assessment of the integrated plant response to emergency or abnormal situations crossing several plant systems and/or safety functions
- 2. Include the parent question for bank and modified questions. BC comment ->If you have give power level in the stem (like 50 or 100%), why include Mode 1? Seems like extra info that is NOT needed.

41.7 Reference Picture To make the distractors more plausible change the first half of the distractor to: A and C, A and D, B and C, B and D. Put them in a logical order like above and then make the correct answer match the A and D choice. The way it is currently written the logical distractor is not even a choice for applicant. Also in the distractor analysis for the incorrect choices securing the RHR pump is plausible because AOP-34 does secure the RHR pump but not until after the injection valve is overridden and closed to prevent auto start.

41.2 Distractor B and D are not credible why would anyone select the level of the main steam lines as the point that you would fill to or the steam Dryers? Second question is this RO level knowledge, since the reference to the correct answer is in the EOP basis? Reword the question with same initial conditions to ask per EOP-1 the band to maintain level in is 10 to 51 inches, 45 to 100 inches, -20 to 51 inches or 75 to 100 inches.
Each of these bands are levels that correspond a level band in either EOP-1 or the ability to cool down to less Thant 200 degrees in NC. BC comments -> I agree with the question not being RO level. I thought the exact same thing and was wondering why in the distractor explanation a procedure would not be referenced vs EOP basis. As, I'm not much of a BWR guy, couldn't recall level of dryers as compared to steam lines so didn't pick Answer B as not valid, but immediately thought Answer D was not a valid distractor. I like the recommendation of using RPV levels based on procedural requirements

41.8 Reference Picture, Have a question as to what RCS pressure goes to during the "smallest LBLOCA" is it greater than or less than 480psig? Is there a direct entry into EOP-1A I thought it needed to be entered from EOP-1 or EOP-4A. Going from EOP-1 to EOP-1A creates a subset issue. if the answer is EOP-1A then EOP-1 could also be correct making EOP-1A not a possible distractor. BC comments -> not sure I understand your comments above. The correct answer is EOP-1 NOT EOP-1A, so no subset issue. I could not find Encl 26 (TSG-3.10) in the references. How do the operators know that a single control rod stuck fully out will NOT impact the reactor remaining shutdown? This information is in the basis section of TS, so appears to be SRO only knowledge????

41.7 Reference Picture, What would make not firing plausible?
Power is needed to fire off the valves and no one would design a boiler that any partial loss of power would fire a squib valve right. BC comments -> What is the value of including the picture, since already indicated no power? If no continuity, how is the circuit going to actuate? I don't like the idea of telling a candidate that the bkr to the pump is open, should tell them a condition and then let them determine impact on component(s).
Recommend rewriting, getting rid of picture and question something along the lines of "Panel EHS-MCC2A has lost power. In this condition, manually initiating SLC A would result in SLC Pump A ____1____ and Squib Valve A ___2____: A.

> I thought 1 implausible distractor made it an "E" vs. a "U."
Also, recommend: changing stem to say: 1) "Inverter BYS-INV01B lost ALL power." and 2) changing remainder of the stem to say "As a direct result of this transient, reactor water level will ____." The operators should know what impact the loss of that inverter will have on plant equipment and shouldn't be included in the stem - dumbs down the question. With that information, I knew level would increase, so automatically threw out Answers C and D as implausible 22 F

D 41.5 Reference Provided, When I read the distractor analysis I understand the plausibility of the 250 and 70 but not the 140 please explain how this is plausible. LOD is a 2 not 3. BC comments -> 1 implausible distractor makes it an "E" vs. a "U." The 140 (I would call it 130 - 135) is shell side pressure, so I see how the could get this wrong. However, I initially thought only answers B and D were plausible, because pressure, but they could read the chart incorrectly, so ok with Answers A and C.

A 41.7 extra space between a and steam in stem. There is a subset issue in the second half of the question if the system will automatically operate at >= 45 psig then it will automatically operate at >= 60 psig as well. This makes all of the second half answers correct. the second question is what makes 60 a plausible distractor? BC comments -> GREAT catch on subset!! I missed that when I looked at it before looking at your explanation. I review the question and try to make my own assessment prior to looking at your Explanation, so I don't get jaded. Maybe change stem to say minimum pressure that it will automatically actuate.

41.10 All Tier 1 questions must meet the objective of testing demonstrated knowledge and proficiency of how to safety operate the plant during emergency or abnormal conditions. Satisfactory ways of meeting this objective include, but are not limited to, the following: (1) information contained in the sites procedures, including alarm response procedures, AOPs, EOPs, and their associated bases documents; (2) diagnosis that leads to selection of the procedures that should be used to respond to the evolution, (3) the progression of an event, and (4) assessment of the integrated plant response to emergency or abnormal situations crossing several plant systems and/or safety functions. While the question as written does meet the K/A it does not meet the tier requirements. Also you have both EOP-2 and AOP -2 listed in the distractors I believe the EOP-2 is a typo. Can you modify the question to have the applicant identify the entry conditions for AOP-2 or some other procedural hook in the first half and then use the TS angle for the second half this will allow you to maintain meeting the K/A and will also let you meet the tier. Also LOD 2, include in distractor analysis where the instrumentation for TS 3.1.1 is required but not the corresponding valve being operable 43 F

43.5 Free Review Question: Since step 5.3 and 5.4 are at the discretion of the CRS/OSM what makes one a higher priority than the other? Need more detail in distractor analysis. In the distractor analysis you state that at EOL there is greater than 50 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br /> to boil. If the plant is at the BOL the fuel has not been in the pool for near as long as it would have been at the end of life. What would the time be if it has been 20 days since the core off-load? Need to either include that shortest time for a refueling SFP temperatures or provide something in the stem like changing the 100% BOL to EOL so the numbers you have in the detractor analysis work. Also provide information where the 50 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br /> comes from. Add in the distractor analysis why providing service water to SFP cooling is a plausible answer. The reasons that it is plausible are that it is a step in the AOP, and if the applicant believed that the reactor was already scrammed the SFP would be a higher concern than restoring CRD pumps. The current stance from the headquarters is that inclusion of a picture is the same as a handout. I am fine with the picture just information for you.
RBS: Change the initial conditions from EOL to BOL 3 days after a refueling outage. This would greatly shorten the time to boil for the spent fuel pool making the distractors about placing the Fuel Coolers in service more plausible. Added more supporting information in the explanation and distractor analysis. Minor change request that the initial conditions be modified to three days after a 21 day refueling outage and add a line giving SFP temperature of 130 degrees. makes the distractors more credible. Also the distractor analysis clip from AOP -51 should be for the 24 day line not the 3 day line either way it still shows about 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> to 200 degrees.

43.5 Free Review Question: Question is in TS basis for SRO only information. All Tier 1 questions must meet the objective of demonstrated knowledge and proficiency of how to safety operate the plant during emergency or abnormal conditions..
Satisfactory ways of meeting this objective include, but are not limited to, the following: (1) information contained in the sites procedures,including alarm response procedures, AOPs, EOPs, and their associated bases documents; (2) diagnosis that leads to selection of the procedures that should be used to respond to the evolution, (3) the progression of an event, and (4) assessment of the integrated plant response to emergency or abnormal situations crossing several plant systems and/or safety functions. The question is a good one except for that it does not address any abnormal condition which is what tier 1 is supposed to address. Look at FAQ 401.55 for the revised information. Consider revising the question to incorporate an ARP, AOP, EOP abnormal condition addressed from a proceduaral prospective.

43.2 Free Review Question: what type if insturmetation is installed on 480 volt switchgear to monitor for an open phase? I know that there was an industry push for monitoring for open phases at the main transformer switchyard level. I had not heard of any effort for open phase protection at the switchgear level. Please provide me with the specific open phase protection for Riverbend at the switchgear level and what it is protecting against. With this being said I believe that the open phase answers are not credible distractors.
RBS: changed the distractor Open Phase to Undervoltage. This more plausible due to the fact 480 buses have undervoltage relays that alert operators in the control room.

Restoration of IAS to containment first before the CCP system could be considered the overall mitigative strategy. While the note indicates that the restoration of IA is very important it also has a note that indicates the restoration of CCP is important. Is there any documentation as to exactly why one is of higher importance than the other. Please include some of this information in the distractor analysis to try to shore up the SRO only argument.

43.5 Free Review Question: CFR need to be 43.X best fit would be 43.5. Picture constitutes a reference. The K/A says to use procedures to mitigate the abnotmal condition. If you were to add in accordance with procedure XYZ the CRS will first direct XXXXX. the second half of each distractor can be elimintated using system knowledge only. THe first half of the question is an RO level question so this does not meet the SRO only guidance.
RBS: Changed the second part of the question to make the question SRO level.
Reference Provided Still in need of some modificaiton, Now that a TRM will be provided I need a copy of the actual proposed handout to the student to finish my evaluation. BC comments -> not a fan of this question because seems obvious that if channel fails downscale, actual water level will increase, so can throw out Answers A and B. Why not in the stem indicate one of the steam flow inputs failed high (the explanation for Answer C talks about steam flow failing high and indicates this is shown on a picture, but I don't see a picture.). Is the BWR level control system level dominate? If so, seems like level would increase, but stabilize at some higher level 90 F
