==Dear Sir:==
 
The Penn State Breazeale Reactor would like to make the following comments 00nceming the Reactor Operator Written Exam given to Pat Boyle by you on March 25,1991.
C. Plant and Rndintbn Monitorina Systems Question #19 f
Which one of the following instruments monitors the radiation level at the primary pool water surface? NRC answer is c. . A GM tube attached to the bridge section at the primary tank top. NRC reference is PSU TRIGA MARK 11 General Characteristics Section 7.A.2., a domment not submtted by PSU as training material.
Facility comment The above reference document was probably prepared by General Atomics, the Triga manuf acturer,25 years ago and is not a current document. The present monitoring on the reactor bridge consists of lon chambers. So the correct answer is b. An ion chamber attached to the bridge section at the primary tank top. PSU reference is section 4.14 of the training manual subrrdtted to the NRC for exam preparation.
C. Plant and Radiathn Monitorina Systems - Quention #20 While performing experiment 39, Bath Coefficient of Reactivity, primary coolant temperature has been reduced to 7 degrees C. Which one of the following methods is used to increase the temperature? NRC answer is d. Use underwater light and heat from the pumps. NRC reference is PSU TRIGA MARK li General Characteristics Section 7.A.2., a document not submitted by PSU as training material.
Facility comment The above reference document was probably prepared by General Atomics, the Triga manuf acturer,25 years ago and is not a current document. Penn State requests that
'[                        this question be removed f rom the exam, since there is not reason to expect that the bcense candidate would have knowledge of this experirnent, it should be noted that the training manager, who has worked at the Penn State Breazealo Reactor for 23 years, has no knowledge of
  !                        this experiment.
                          - Ooeratino Test
  !                        During the operating test the examiner had the license candidate use procedure EP-4, Loss of
(                        Pool Water, section C.2. on page 3, to show how to provido pool water fill using university water through the deminerattzer. During this exercise,the candidate was unable to locate valves 33,34, and 39. The reactor staff has determined that these valves no longer exist;they were in service at one time as a part of a fission product monitor system that is no longer in service. The necessary changes will be made to procedure EP 4.

i      i NRC RULES AND GUIDELINES FOR LICENSE EXAMINATIONS During the administration of this examination the following rules apply:
: 1. Cheating on the examination means an automatic denial of your applicetion and could recult in more severo penalties.
: 2. After the examination hac deen completed, you must cign the statement on the cover sheet indicating that the work is your own and you have not received or given assictance in completing the examination. This must be done after you complete the exemination.
: 3. Restroom trips are to be limited and only one candidate at a time may leave.                          You must avoid all contacts with enyone outside the examination room to avoid even the appearance or possibility of cheating.
: 4. Use bleck ink or dark pencil only to facilitate legible reproductions.
: 5. Print your name in the blank provided in the upper right-hand corner of l            the examination cover sheet.
: 6. Fill in the date on the cover sheet of the examination (if necessary).
: 7. You may wri te your ' answere on the examination question page or on a separate sheet of paper.                                          USE ONLY THE PAPER PROVIDED AND DO NOT WRITE ON THE BACK SIDE OF THE PAGE.
B. If you write your answers on the examination question page and you need more space to answer a specific question, use a separate sheet of the paper provided and insert it directly after the specific question.                                                                                    DO NOT WRITE ON THE BACK SIDE OF THE EXAMINATION QUESTION PAGE.
: 9. Print your name in the upper right-hand corner of the first page of each section of your answer sheets whether you use the examination question pages or separate sheets of paper.                                                Initial each page.
: 10. Before you turn in your examination, consecutively number each answer sheet, including any additional pages inserted when writing your answers on the examination question page.
: 11. If you are using separate sheets, number each answer as to category and.
number (i.e. Plant Systems # 04, EPE #-10) and skip at least 3 lines between answers to allow space for grading.
: 12. Write "End of Category" at the endaof your answers to a category.
: 13. Start each' category on a new page.
: 14. Write "Last Page" on the last answer sheet.
: 15. Use abbreviations only if they are commonly used in facility literature.
Avoid using symbols such as < or > nigns to avoid a simple transposition error resulting in an incorrect answer. Write it out.

: 16. The point value for each question is indicated in parentheses after the question. The amount of blani space on an examination question page is NOT an indication of the depth of answer required.
: 17. Show all calculations. methods, or assumptions used to obtain an answer.
: 18. Pertiel credit may be given. Therefore. ANSWER ALL PARTS OF THE OUESTION AND DO NOT LEAVE ANY ANSWER BLANK.                                                                                              NOTE: partial credit will NOT bu given on multiple choice questions.
19.-Proportional grading will be applied.                                                                                                                            Any additional wrong information that is provided may-count against you.                                                                                          For example, if a question is worth one point and asks for four responses,                                                                                              each of which is worth O.25 points, and you give five responses, each of your responses will be worth 0.20 points.                                                              If one of your five responses is incorrect, 0.20 will be
                                                                -deducted and your total credit for that question will be 0.80 instead of 1.00-even though you got the four correct answers.
: 20. If the intent of a question is unclear, ask questions of the examinor only.
: 21. When turning in your examination, assemble the completed examination with examination questions, examination aids and answer sheets.                                                                                              In addition, turn in all scrap paper.                                                                                                                                                  ,
: 22. To pass the examination, you must achieve at least 70% in each category.
h                                  23..There is a time limit of (3) hours for completion of the examination.
(or sonne other time 11 less than the ful1 examination is taken.)
: 24. When you are done end'have turned in your examination, leave the examin-ation area as-defined by the examiner.                                                                                            If you are found in this area while the exomination is still in progress, your license may be denied or revoked.

Which one of the following is the design feature of the PSBR reactor that is the MAJOR contributor to the large prompt negative temperature coefficient.
: e. Doppler effect. The increased energy of the U-230 atoms causes a broadening of the resonance peaks
: b. Core leakage. As the moderator heats up there are more neutrons a higher energies causing increased core leakage
: c. Zirconium abcorption. As the circonium heets up its resonance obsorption cross section increases causing more neutron absorption
: d. Cell effect. As the fuel heats up the neutron energy loss increases due to hydrogen atoms in the Zirconium hydride fuel mixture QUESTION: 004                      (1.00) fn the subcritical range of start-up, the reactor operator observes an increase in neutron population on the log count rate recorder, but notices there is not a corresponding indication on the period meter.
Which one of the following explains this response?
: a. The compensating voltage on the Linear channel is set too low and thus is not reflecting counts and period
: b. The gamma-to-neutron ratio is so high that count rate must be increased significantly before there is any period indication
: c. The fission chamber is in saturation and therefore not producing a period indication
: d. The flux level during the subcritical range of startup is not high enough to register an indication on the log N channel.

Dear Sir:

The Penn State Breazeale Reactor would like to make the following comments 00nceming the Reactor Operator Written Exam given to Pat Boyle by you on March 25,1991.

C. Plant and Rndintbn Monitorina Systems Question #19 f

Which one of the following instruments monitors the radiation level at the primary pool water surface? NRC answer is c. . A GM tube attached to the bridge section at the primary tank top. NRC reference is PSU TRIGA MARK 11 General Characteristics Section 7.A.2., a domment not submtted by PSU as training material.

Facility comment The above reference document was probably prepared by General Atomics, the Triga manuf acturer,25 years ago and is not a current document. The present monitoring on the reactor bridge consists of lon chambers. So the correct answer is b. An ion chamber attached to the bridge section at the primary tank top. PSU reference is section 4.14 of the training manual subrrdtted to the NRC for exam preparation.

C. Plant and Radiathn Monitorina Systems - Quention #20 While performing experiment 39, Bath Coefficient of Reactivity, primary coolant temperature has been reduced to 7 degrees C. Which one of the following methods is used to increase the temperature? NRC answer is d. Use underwater light and heat from the pumps. NRC reference is PSU TRIGA MARK li General Characteristics Section 7.A.2., a document not submitted by PSU as training material.

Facility comment The above reference document was probably prepared by General Atomics, the Triga manuf acturer,25 years ago and is not a current document. Penn State requests that

'[ this question be removed f rom the exam, since there is not reason to expect that the bcense candidate would have knowledge of this experirnent, it should be noted that the training manager, who has worked at the Penn State Breazealo Reactor for 23 years, has no knowledge of

! this experiment.

- Ooeratino Test

! During the operating test the examiner had the license candidate use procedure EP-4, Loss of

( Pool Water, section C.2. on page 3, to show how to provido pool water fill using university water through the deminerattzer. During this exercise,the candidate was unable to locate valves 33,34, and 39. The reactor staff has determined that these valves no longer exist;they were in service at one time as a part of a fission product monitor system that is no longer in service. The necessary changes will be made to procedure EP 4.

i i NRC RULES AND GUIDELINES FOR LICENSE EXAMINATIONS During the administration of this examination the following rules apply:

1. Cheating on the examination means an automatic denial of your applicetion and could recult in more severo penalties.
2. After the examination hac deen completed, you must cign the statement on the cover sheet indicating that the work is your own and you have not received or given assictance in completing the examination. This must be done after you complete the exemination.
3. Restroom trips are to be limited and only one candidate at a time may leave. You must avoid all contacts with enyone outside the examination room to avoid even the appearance or possibility of cheating.
4. Use bleck ink or dark pencil only to facilitate legible reproductions.
5. Print your name in the blank provided in the upper right-hand corner of l the examination cover sheet.
6. Fill in the date on the cover sheet of the examination (if necessary).
7. You may wri te your ' answere on the examination question page or on a separate sheet of paper. USE ONLY THE PAPER PROVIDED AND DO NOT WRITE ON THE BACK SIDE OF THE PAGE.

B. If you write your answers on the examination question page and you need more space to answer a specific question, use a separate sheet of the paper provided and insert it directly after the specific question. DO NOT WRITE ON THE BACK SIDE OF THE EXAMINATION QUESTION PAGE.

9. Print your name in the upper right-hand corner of the first page of each section of your answer sheets whether you use the examination question pages or separate sheets of paper. Initial each page.
10. Before you turn in your examination, consecutively number each answer sheet, including any additional pages inserted when writing your answers on the examination question page.
11. If you are using separate sheets, number each answer as to category and.

number (i.e. Plant Systems # 04, EPE #-10) and skip at least 3 lines between answers to allow space for grading.

12. Write "End of Category" at the endaof your answers to a category.
13. Start each' category on a new page.
14. Write "Last Page" on the last answer sheet.
15. Use abbreviations only if they are commonly used in facility literature.

16. The point value for each question is indicated in parentheses after the question. The amount of blani space on an examination question page is NOT an indication of the depth of answer required.
17. Show all calculations. methods, or assumptions used to obtain an answer.
18. Pertiel credit may be given. Therefore. ANSWER ALL PARTS OF THE OUESTION AND DO NOT LEAVE ANY ANSWER BLANK. NOTE: partial credit will NOT bu given on multiple choice questions.

19.-Proportional grading will be applied. Any additional wrong information that is provided may-count against you. For example, if a question is worth one point and asks for four responses, each of which is worth O.25 points, and you give five responses, each of your responses will be worth 0.20 points. If one of your five responses is incorrect, 0.20 will be

-deducted and your total credit for that question will be 0.80 instead of 1.00-even though you got the four correct answers.

20. If the intent of a question is unclear, ask questions of the examinor only.
21. When turning in your examination, assemble the completed examination with examination questions, examination aids and answer sheets. In addition, turn in all scrap paper. ,
22. To pass the examination, you must achieve at least 70% in each category.

h 23..There is a time limit of (3) hours for completion of the examination.

A. RX THEORY, THERMO 6 FAC OP CHARS Page 5 OUESTION: 007 (1.00)

Which one of the following is the design feature of the PSBR reactor that is the MAJOR contributor to the large prompt negative temperature coefficient.

e. Doppler effect. The increased energy of the U-230 atoms causes a broadening of the resonance peaks
b. Core leakage. As the moderator heats up there are more neutrons a higher energies causing increased core leakage
c. Zirconium abcorption. As the circonium heets up its resonance obsorption cross section increases causing more neutron absorption
d. Cell effect. As the fuel heats up the neutron energy loss increases due to hydrogen atoms in the Zirconium hydride fuel mixture QUESTION: 004 (1.00) fn the subcritical range of start-up, the reactor operator observes an increase in neutron population on the log count rate recorder, but notices there is not a corresponding indication on the period meter.

Which one of the following explains this response?

a. The compensating voltage on the Linear channel is set too low and thus is not reflecting counts and period
b. The gamma-to-neutron ratio is so high that count rate must be increased significantly before there is any period indication
c. The fission chamber is in saturation and therefore not producing a period indication
d. The flux level during the subcritical range of startup is not high enough to register an indication on the log N channel.
