Initials Item Task Description 1.

a. Verify that the outline(s) fit(s) the appropriate model, in accordance with ES-401.

R b. Assess whether the outline was systematically and randomly prepared in accordance with I Section D.l of ES-401 and whether all K/A categories are appropriately sampled.

T T C. Assess whether the outline over-emphasizes any systems, evolutions, or generic topics.

L N I d. Assess whether the justifications for deselected or rejected K/A statements are appropriate.

a. Using Form ES-301-5, verify that the proposed scenario sets cover the required number of normal evolutions, instrument and component failures, technical specifications,
r. and major transients.

1 b. Assess whether there are enough scenario sets (and spares) to test the projected number and mix of applicants in accordance with the expected crew composition and rotation schedule without compromising exam integrity, and ensure that each applicant can be tested using

, at least one new or significantly modified scenario, that no scenarios are duplicated from the applicants audit test(s), and scenarios will not be repeated on subsequent days.

C. To the extent possible, assess whether the outline(s) conform(s) with the qualitative and quantitative criteria specified on Form ES-301-4 and described in Appendix D.

3. a. Verify that the systems walk-through outline meets the criteria specified on Form ES-301-2:

41) the tasks are distributed among the topics as specified on the form
42) at least one task is new or significantly modified (3) no more than one task is repeated from the last two NRC licensing examinations
c. Determine if there are enough different outlines to test the projected number and mix of applicants and ensure that no items are duplicated on subsequent days.
4. a. Assess whether plant-specific priorities (including PRA and IPE insights) are covered in the amrotxiate exam section.

u E b. Assess whether the 10 CFR 55.41/43 and 55.45 sampling is appropriate.

N c. Ensure that WA importance ratings (except for plant-specific priorities) are at least 2.5.

E .

R d. Check for duplication and overlap among exam sections.

1. Check the applicant level and enter the operating test number and Form ES-D-1 event numbers for each event type; TS are not applicable for RO applicants. ROs must serve in both the at-the-controls (ATC) and balance-of-plant (BOP) positions; Instant SROs must serve in both the SRO and the ATC positions, including at least two instrument or component (I/C) malfunctions and one major transient in the ATC position. If an Instant SRO additionally serves in the BOP position, one I/C malfunction can be credited toward the two I/C malfunctions required for the ATC position.
2. Reactivity manipulations may be conducted under normal or controlled abnormal conditions (refer to Section D.5.d) but must be significant per Section C.2.a of Appendix D. (*) Reactivity and normal evolutions may be replaced with additional instrument or component malfunctions on a 1-for-1 basis.
3. Whenever practical, both instrument and component malfunctions should be included; only those that require verifiable actions that provide insight to the applicants competence count toward

- the minimum requirements specified for the applicants license level in the right-hand columns.

lote: yf Ensure that at least two topics from every applicable WA category are sampled within each tier of the RO and SRO-only outlines (i.e., except for one category in Tier 3 of the SRO-only outline, the Tier Totals in each WA category shall not be less than two).

a: 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 e1 from that specified in the table based on NRC revisions. The fina RO exam must total 75 points and the SRO-only exam must total 25 points.

Systemslevolutions within each group are identified on the associated outline; systems or evolutions that do not apply at the facility should be deleted and justified; operationally important, site-specific systems that are not included on the outline should be added. Refer to Section D.l.b of ES-401for guidance regarding the elimination of inappropriate WA statements.

Select topics from as many systems and evolutions as possible; sample every system or evolution in the group before selectin!

a second topic for any system or evolution.

Absent a plant-specific priority, only those WAS 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.

Select SRO topics for Tiers 1 and 2 from the shaded systems and WA categories.

The generic (G) WAS in Tiers 1 and 2 shall be selected from Section 2 of the WA Catalog, but the topics must be relevant to the applicable evolution or system. Refer to Section D.l.b of ES-401 for the applicable WAS.

d On the following pages, enter the WA numbers, a brief description of each topic, the topics importance ratings (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 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.

For Tier 3,select topics from Section 2 of the WA catalog, and enter the WA numbers, descriptions, IRs, and Doint totals (#) on Form ES-401-3. Limit SRO selections to WAS that are linked to 10 CFR 55.43.
