INTRODUCTION Science Applications, Inc.
(SAI),
as technical assistance contractor to the U.S. Nuclear Regulatory Commission, has evaluated the response by Carolina Power and Light Company (CPKL) for the Brunswick Steam Electric Plant, Unit 1 (Docket 50-325) and Unit 2 (Docket 50-324) to certain requirements contained in post-TMI Action Items I.A.2.1, Immediate Upgrading of Reactor Operator and Senior Reactor Operator Training and Qualification, and II.B.4, Training for Mitigating Core Damage.
These requirements were set forth in NUREG-0660 (Reference
- 1) and were subsequently clarified in NUREG-0737 (Reference 2).*
. The purpose of the evaluation was to determine whether the licensee's operator training and requalification programs satisfy the requirements.
The evaluation pertains to the following Technical Assignment Control (TAC) System numbers:
.A.2.1 II.B.4 Unit 1 Unit 2 44146 44147 44496 44497 As delineated
- below, the evaluation covers only some aspects of item I.A.2.1.4.
The detailed evaluation of the licensee's submittals is presented in Section IV; the conclusions are in Section V.
II.
SCOPE AND CONTENT OF THE EVALUATION A.
I.A.2.1:
Immediate Upgrading of RO and SRO Training and Qualifications The clarification of TMI Action Item I.A.2.1 in NUREG-0737 incor-porates a letter and four enclosures, dated March 28, 1980, from Harold R.
- Denton, Director, Office of Nuclear Reactor Regulation, USNRC, to all power reactor applicants and licensees, concerning qualifications of reactor oper-ators (hereafter referred to as Denton's letter).
This letter and enclo-sures imposes a number of training requirements on power reactor licensees.
This evaluation specifically addressed a subset of the requirements stated in Enclosure 1'of Denton's letter, namely:
Item A.2.c, which relates to operator'raining requirements; item A.2.e, which concerns instructor requalification; and Section C, which addresses operator requalification.
Some of these requirements are elaborated in Enclosures 2,
3, and 4 of Denton's letter.
The training requirements under evaluation are summarized in Figure 1.
The elaborations of these requirements in Enclosures 2,
3, and 4 of Denton's letter are shown respectively in Figures 2,
3, and 4.
- Enclosure 1 of NUREG-0737 and NRC's Technical Assistance Control System distinguish four sub-actions within I.A.2.1 and two sub-actions within II.B.4.
These subdi v i s i ons are not carr i ed for ward to the actual presentation of the requirements in Enclosure 3 of NUREG-0737. If they had been, the items of concern here would be contained in I.A.2.1.4 and II.B.4.1.

As noted in Figure 1, Enclosures 2 and 3 indicate minimum require-ments concerning course content in their respective areas.
In addition, the Operator Licensing Branch in NRC has taken the position (Reference
- 3) that the training in mitigating core damage and related subjects should consist of at least 80 contact hours* in both the in'itial training and the requali-fication programs.
The NRC considers thermodynamics, fluid flow and heat transfer to be related
- subjects, so the 80-hour requirement applies to the combined subject areas of Enclosures 2 and 3.
The 80 contact hour criterion is not intended to be applied rigidly; rather, its purpose is to provide greater assurance of adequate course content when the licensee's training courses are not described in detail.
Since the licensees generally have their own unique course out-
- lines, adequacy of response to these requirements necessarily depends only on whether. it is at a level of detail comparable to that specified in the enclosures (and consistent with the 80 contact hour requirement) and whether it can reasonably be concluded from the licensee's description of his train-ing material that the items in the enclosures are covered.
The Institute of Nuclear Power Operations (INPO) has developed its own guidelines for training in the subject areas of Enclosures 2
and 3.
These guidelines, given in References 4
and 5, were developed in response to the same requirements and are more than adequate, i.e., training programs based specifically on the complete INPO documents are expected to satisfy all the requirements pertaining to training material which are addressed in this evaluation.
The licensee's response concerning increased emphasis on tran-sients is considered by SAI to be acceptable if it makes explicit reference to increased emphasis on transients and gives some indication of the nature of the increase, or, if it addresses both normal and abnormal transients (without necessarily indicating an increase in emphasis) and the requalifi-cation program satisfies the requirements for control manipulations, Enclo-sure 1, Item C.3.
The latter requir ement calls for all the manipulations listed in Enclosure 4 (Figure 4 in this report) to~e performed, at the frequency indicated, unless they are specifically not applicable to the licensee's type of reactor(s).
Some of these manipulations may be performed on a simulator.
Personnel with senior licenses may be credited with-these activities if they direct or evaluate control manipulations as they are performed by others.
Although these manipulations are acceptable for meet-ing the reactivity control manipulations required by Appendix A paragraph 3.a of 10 CFR 55, the requirements of Enclosure 4 are more demanding.
Enclosure 4 requires about 32 specific manipulations over a two-year cycle while 10 CFR 55 Appendix A requires only 10 manipulations over a two-year cycle.
B.
II.B.4:
Training for Mitigating Core Damage Item II.B.4 in NUREG-0737 requires that "shift technical advisors and operating personnel from the plant manager through the operations chain
- A contact hour is a one-hour period in which the course instructor is present or available for instructing or assisting students;
- lectures, seminars, discussions, problem-solving sessions, and examinations are considered contact periods.
This definition is taken from Reference 4.
6
to the licensed operators" receive training on the use of installed systems to control or mitigate accidents in which the core is severely damaged.
Enclosure 3 of Denton's letter provides guidance on the content of this training.
"Plant Manager" is here taken to mean the highest ranking manager at the plant site.
For licensed personnel, this training would be redundant in that it is also required, by I.A.2.1, in the operator requalification program.
However, II.B.4 applies also to operations personnel who are not licensed and are not candidates for licenses.
This may include one or more of the highest levels of management at the plant.
These non-licensed personnel are not explicitly required to have training in heat transfer, fluid flow and thermodynamics and are therefore not obligated for the full 80 contact hours of training in mitigating core damage and related subjects.
Some non-operating personnel, notably managers and technicians in instrumentation and control, health physics and chemistry departments, are supposed to receive those portions of the training which are commensurate with their responsibilities.
Since this imposes no additional demands on the program itself, we do not address it in this evaluation. It would be appropriate for resident inspectors to verify that non-operating personnel receive the proper training.
The required implementation dates for all items have passed.
- Hence, this evaluation did not address the dates of implementation.
- Moreover, the evaluation does not cover training program modifications that might have been made for other reasons subsequent to the response to Denton's letter.
II I.

This letter contains details that are not in the program descriptions and, for purposes of this evaluation, is considered to be an, integral part of the licensee's training program description.
IV. EVALUATION SAI's evaluation of the training-programs at Carolina Power and Light Co.'s Brunswick Steam Electric Plant is presented below.
Section A
addresses TMI Action Item I.A.2.1 and presents the assessment organized in the manner of Figure 1.
Section B addresses TMI Action Item II.B.4.
A.
I.A.2.1:
Immediate Upgrading of Reactor Operator and Senior Reactor Operator Training and gualification.
Enclosure 1
Item A.2.c 1
The basic requirements are that the training programs given to reactor operator and senior reactor operator candidates cover the subjects of heat transfer, fluid flow and thermodynamics at the level of detail specified in Enclosure 2 of Denton's letter.
CPEL provides separate training programs for Reactor Operators (ROs) and Senior Reactor Operators (SROs).
The RO training program (Training Instruction TI-201) involves 10-12 weeks of training.
The list of instruction topics includes heat transfer, fluid flow, and thermodynamics as a single major section.
Within this section, the list of subtopics is identical to the numbered topics in Enclosure 2 (see Figure 2),
but no further detail on training course content is provided.
The SRO training program (TI-202) responds to the NUREG-0737 requirement in precisely the same way, i.e.,
a new section has been added to the list of topics.
In addition, heat transfer and fluid flow are also included as subtopics under Reactor Theory and implicitly in other sections.
Although detailed course content is not provided, the fact that CPEL has structured their program specifically in terms of the subtopics of Enclosure 2,
combined with their assertion that they meet all the require-
- ments, constitutes an implicit commitment to both the content and the level
'of detail of Enclosure 2.
Neither program gives a distribution of hours among the major topics.
The section devoted to heat transfer, fluid flow, and thermody-namics is one of eleven major sections covered in the 10-12 week training period.
- However, CP8L's response (submittal item 6) to a request for addi-tional information indicated that 40 classroom hours are devoted to heat transfer, fluid flow and thermodynamics in both the RO and SRO training programs.
This is fully one-half of the hours required by NRC for the entire area of mitigating core damage and related subjects.
We conclude that CPEL meets the requirements of this item in their training programs at the Brunswick plant.
Enclosure 1
Item A.2.c 2 The requirements are that the training programs for reactor and senior reactor operator candidates cover the subject of accident mitigation at the level of detail specified in Enclosure 3 of Denton's letter (see Figure 3 of this report).
The licensee responded to this requirement, just as he did with the previous
- one, by adding a new major section to the list of training topics.
In this case, the section is called "Mitigating Core Damage" and is included in both the RO and SRO training programs.
Again, the subtopics are precisely the same as in the relevant enclosure (Enclosure 3) to Denton's letter.
Although no further detail is provided in the program descriptions themselves, CPSL's response (submittal item 6) to a request for additional 9
p ab
information (Reference
- 6) provides both an outline and a "Presentation,"
the latter being a more detailed outline written in the nature of a syllabus.
These outlines provide more detail than Denton's enclosure.
- Moreover, they indicate that Denton's letter itself and Enclosure 3 are explicitly included as a reference to discussion topics.
Students receive a copy of the enclo-sure.
The licensee
- notes, however, that this material is not covered as a
unit but is incorporated into all current training subjects as appropriate, e.g.,
ECCS training.
As of January 1982, RO and SRO training is broken down by hours approximately as follows:
40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> 40 hours 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> 8 hours 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> 4 hours Heat Transfer, Fluid Flow and Thermodynamics ECCS Training Emergency Plan Training Transients Design Basis Accidents Accident Mitigation with Core Damage (AMWCD)
The 4-hour segment on accident mitigation is actually described as a "summary class" which integrates information from all training segments into the core damage context.
The licensee notes that core damage mitigation is treated continuously throughout the 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> of ECCS training.
As described, this training program clearly meets the 80 contact hour criterion.
CPEL indicates a somewhat different breakdown for training already given to present personnel, but it still includes more than 80 contact hours.
We conclude the licensee meets this, requirement.
Enclosure 1
Item A.2.c 3
The requirement is that there be an increased emphasis in the training program on dealing with reactor transients.
The licensee asserts tha't the Lesson Plan for Plant Transients has been updated.
Lectures cover all transients analyzed in the FSAR, including DBAs.
The program is updated after each reload, based on supplemental reload licensing information supplied by their reactor vendor.
The training related to transients includes four days at the Limerick Simulator.
We conclude the licensee meets this requirement.
Enclosure 1
Item A.2.e The requirement is that instructors for reactor operator training programs be enrolled in appropriate requalification programs to assure they are cognizant of current operating
- history, problems and changes to procedures and administrative limitations.
CPEL states in submittal item 6 that all licensed operator instructors participate fully in the regular retraining program for licensed operators.
(The instructors are taught by an instructor who has received training from GE, the reactor vendor.)
The retraining program includes a
review of "...facility design
- changes, procedure
- changes, and facility license changes, significant safety-related modifications or changes to 10
~I
~
~I
~
procedures and license...."
This review is documented in the training files.
The licensee's response is adequate and therefore meets the requirement.
Enclosure 1
Item C.1 The primary requirement is that the requalification programs have instruction in the areas of heat transfer, fluid flow, thermodynamics and accident mitigation.
The level of detail required in the requalification program is that of Enclosures 2
and 3 of Denton's letter..
In addition, these instructions must involve an adequate number of contact hours.
The retraining program at Brunswick (TI-200) reflects this requirement by the addition of two major sections (as in the training programs) to the topic outline, one covering heat transfer, fluid flow and thermodynamics, the other covering mitigation of core damage.
- Again, the sub-topics are the unnumbered topics from Denton's Enclosures 2
and 3.
The elaboration of technical content in the core mitigation section given in submittal item 6 would also apply to the retraining program.
- Hence, with regard to technical
- content, the retraining program is satisfactory to the same extent as the,training programs, with a minor reservation as discussed below.
CPKL indicates that the course outlines identify topics which
~ma be covered.
Each year, the annual examination results are used to formulate the retraining program for the following year.
Consequently, there is no assurance that a particular subtopic would be covered in any given year.
There is no provision for this type of flexibility in NUREG-0737.
- However, it apparently's consistent with NRC practice with training in general and there is no obvious reason why an exception should be made here.
We conclude the content of the requalification program is adequate and therefore that the requirement is satisfied.
On the other
- hand, CPEL allows any operator who "... clearly shows he would have passed an NRC exam..." on a particular subject (with a score of 80%%d or greater) to be exempt from lectures on that subject.
This would not be logically inconsistent with the practice noted earlier, but it raises the question of how one demonstrates he would have passed a test without taking the test.
Presuming CPEL's practice to have been approved for other
- subjects, we refrain from questioning it here.
We would suggest,
- however, that the resident inspector obtain some clarification from CPEL.
As of January
- 1982, the annual retraining program is broken down approximately as follows:
24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 24 hours 4

In addition, of 32 related to mitigating core identified

- These, combined with the 64 hours7.407407e-4 days <br />0.0178 hours <br />1.058201e-4 weeks <br />2.4352e-5 months <br /> 80 hours.
If all the subjects listed are mitigating core damage, as CPSL does, the 80
~
~I
contact hour requirement is clearly met on an annual basis.
- Actually, retraining programs are required only biennially.
We assume, as CP&L implies, that all licensed operators undergo retraining each year.
To some
- extent, this would compensate for the flexibility in formulating the annual program.
We conclude that the 80 contact hour requirement is met.
Enclosure 1
Item C.2 The requirement for licensed operators to participate in the accelerated requalification program must be based on passing scores of 80K
- overall, 70K in each category.
If an operator at the Rrunswick plant receives less than 70K in any category or less than 8(C overall on an examination, he is removed from licensed duties and required to receive accelerated requalification.
The accelerated requalification training is required in any category for which the score is less than 70K or in all categories if the overall score is less than 80K.
This training continues until proficiency is demonstrated via written or oral examinations.
This policy satisfies the requirement.
Enclosure 1
Item C.3 TMI Action Item I.A.2.1 calls for the licensed operator requalifi-cation program to include performance of control mani pul ations involving both normal and abnormal situations.
The specific manipulations required and their performance frequency are identified in Enclosure 4 of the Denton letter (see Figure 4 of this report).
The retraining program identifies explicitly all but one of the 27 manipulations specified in Denton's Enclosure 4.
Item 6 is omitted because it does not apply to boiling water reactors, the type used at Brunswick.
The stated frequency of performance is also in compliance with the requirement.
B.
II.B.4 Training for Mitigating Core Damage Item II.B.4 requires that training for mitigating core
- damage, as indicated in Enclosure 3 of Denton's letter, be given to shift technical advisors and operating personnel from the plant manager to the licensed operators.
This includes both licensed and non-licensed personnel.
The content of the licensee's training in this area is at least as comprehensive as Enclosure 3 of Denton's letter.
- Moreover, the requirement that core damage mitigation training be given to all operations personnel is satisfied, judging from the organization chart provided in'ubmittal item 6.
- Specifically, the following receive the training and are tested on it in the final retraining exams:
shift technical
- advisors, shift operating supervi-sors, shift foremen, senior control operators, reactor operators, all licensed non-operations personnel, manager-operations, manager-plant opera-
- tions, and general manager (The latter two have missed one lecture but will complete the training by June 15, 1982.)
In addition, the managers of maintenance and environmental and radiation control take the training but not the test.
We conclude that CPEL satisfies this requirement.

CONCLUSIONS Based on our evaluation as discussed
- above, SAI concludes that the licensee has met the requirements of NUREG-0737 items I.A.2.1 and II.B.4 with regard to operator training programs at the Brunswick Steam Electric
- Plant, Units 1
and 2.
