3. Generic Knowledge and Abilities 1 2 3 4 10 1 2 3 4 7 Categories 3 2 2 3 2 2 1 2 Note: 1. Ensure that at least two topics from every applicable K/A category are sampled within each tier of the RO and SRO-only outline sections (i.e., except for one category in Tier 3 of the SRO-only section, the Tier Totals in each K/A category shall not be less than two). (One Tier 3 radiation control K/A is allowed if it is replaced by a K/A from another Tier 3 category.)
2. The point total for each group and tier in the proposed outline must match that specified in the table. The final point total for each group and tier may deviate by +/-1 from that specified in the table based on NRC revisions. The final RO exam must total 75 points, and the SRO-only exam must total 25 points.
3. Systems/evolutions within each group are identified on the outline. Systems or evolutions that do not apply at the facility should be deleted with justification. Operationally important, site-specific systems/evolutions that are not included on the outline should be added. Refer to Section D.1.b of ES-401 for guidance regarding the elimination of inappropriate K/A statements.
4. Select topics from as many systems and evolutions as possible. Sample every system or evolution in the group before selecting a second topic for any system or evolution.
5. Absent a plant-specific priority, only those K/As having an importance rating (IR) of 2.5 or higher shall be selected. Use the RO and SRO ratings for the RO and SRO-only portions, respectively.
6. Select SRO topics for Tiers 1 and 2 from the shaded systems and K/A categories.
7. The generic (G) K/As in Tiers 1 and 2 shall be selected from Section 2 of the K/A catalog, but the topics must be relevant to the applicable evolution or system. Refer to Section D.1.b of ES-401 for the applicable K/As.
8. On the following pages, enter the K/A numbers, a brief description of each topic, the topics IRs for the applicable license level, and the point totals (#) for each system and category. Enter the group and tier totals for each category in the table above. If fuel-handling equipment is sampled in a category other than Category A2 or G* on the SRO-only exam, enter it on the left side of Column A2 for Tier 2, Group 2. (Note 1 does not apply). Use duplicate pages for RO and SRO-only exams.
9. For Tier 3, select topics from Section 2 of the K/A catalog and enter the K/A numbers, descriptions, IRs, and point totals (#) on Form ES-401-3. Limit SRO selections to K/As that are linked to 10 CFR 55.43.

G* Generic K/As

  • These systems/evolutions must be included as part of the sample (as applicable to the facility) when Revision 3 of the K/A catalog is used to develop the sample plan. They are not required to be included when using earlier revisions of the K/A catalog.
    • These systems/evolutions may be eliminated from the sample (as applicable to the facility) when Revision 3 of the K/A catalog is used to develop the sample plan.

ES-401 Record of Rejected K/As Form ES-401-4 Tier/Group Randomly Reason for Rejection Selected K/A 1/1 APE 26 AA1.03 This KA tests the ability to operate and / or monitor the RO following as they apply to the Loss of Component Cooling Water: SWS as a backup to the CCWS. Essential Cooling Water does not act as a backup to Component Cooling Water at STP. Therefore, this KA was replaced with APE 26 AA1.05.

1/1 APE 27 AK3.01 This KA tests the knowledge of the reasons for the following RO responses as they apply to the PZR PCS Malfunction:

Isolation of PZR spray following loss of PZR heaters. This is neither an automatic feature nor an operator response if this occurs. Therefore, this KA was replaced with APE 27 AK3.03.

2/1 004 A2.20 This KA tests the ability to (a) predict the impacts of the RO following malfunctions or operations on the CVCS; and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or predations: Shifting demineralizer while the divert valve is lined up to VCT. When shifting demineralizers at STP, flushing to the RHUT is always accomplished first. There is no guidance when this is not done correctly. Therefore, this KA was replaced with 004 A2.11.

2/1 022 A4.03 This KA tests the ability to manually operate and/or monitor in RO the control room: Dampers in the CCS. We do not operate any RCFC dampers in the control room. Therefore, this KA was replaced with 022 A4.05.

2/1 062 K4.03 This KA tests the knowledge of ED AC design feature(s) and/or RO interlock(s) which provide for the following: Interlocks between automatic bus transfer and breakers. STP does not use automatic bus transfer devices. Therefore, this KA was replaced with 062 K4.10.

2/2 001 K5.12 This KA tests the knowledge of the following operational RO implications as they apply to the CRDS: Effects on power of inserting axial shaping rods. STP does not use axial shaping rods. Therefore, this KA was replaced with 001 K5.97.

2/1 006 K3.02 Changed to system 005 K3.01 because the program office is RO changing their interpretation of oversampling in one system to include RO and SRO topics-so if you have two topics already on the RO exam for one system then you must move a random sample of the SRO to another system topic. I have indicated these changes in purple text for now.

2/1 013 K1.18 Changed to system 022 K1.01 because the program office is RO changing their interpretation of oversampling in one system to include RO and SRO topics-so if you have two topics already on the RO exam for one system then you must move a random sample of the SRO to another system topic. I have indicated these changes in purple text for now.

Tier/Group Randomly Reason for Rejection Selected K/A 2/1 061 G2.2.40 Changed to system 062 G2.2.40 because the program office is SRO changing their interpretation of oversampling in one system to include RO and SRO topics-so if you have two topics already on the RO exam for one system then you must move a random sample of the SRO to another system topic. I have indicated these changes in purple text for now.

2/1 026 A2.07 This KA tested the ability to predict the loss of CS pump SRO suction, possibly caused by clogged sump screen, pump inlet high temperature exceeded, cavitation, voiding, or sump level below cutoff (interlock) limit, and use a procedure to correct, control, or mitigate the consequences. STP does not have procedural guidance for these malfunctions on CS pump operation. Therefore, this KA was replaced with 026 A2.08.

2/2 034 A2.02 This KA tested the ability to predict the consequences of a SRO dropped cask, and use a procedure to correct, control, or mitigate the consequences. STP does not analyze for a dropped cask since a single failure proof crane is used.

Therefore, this KA was replaced with 034 A2.01.
