Examination.0 observations During the administration of the operating exams, The examiners noted a disparitybetweentheway.thecandidate'sescortedexaminers(visitors) and the requirement for escorting visitors as contained in-procedure' 5AWI 5.1.1, step'6.2.8.
The procedure requires the escort use their_ badge to open-the Vital Area door, and then let the visitor place their badge.
into the card reader and enter the Vital Area while the' escort'is holding the door open.
Contrary to this requirement, the escorts were allowing l-the visitors to badge in first, then place their badge into the card reader-and enter the Vital Area.
Additional information regarding their failure to follow this AWI is. contained in Inspection Report Nos. 282/87016 and-l 306/87015.
L 3.
Written Examination-1 After the SR0 written examination was administered on' November 3, 1987, a copy of the examination questions with answer key (see Enclosure 2) was supplied to the facility's training. staff for their review and comment.
2 o_
i f-Subsequent to their review, the licensee transmitted their comments on the written exam in a letter from Mr. E. L. Watzl to Mr.' G. C. Wright, dated November 9, 1987 (see Attachment'l to this report).
Each comment on specific questions has been reviewed in depth and was evaluated on its merits.
A resolution to each of these comments is contained as Attachment 2 to this report.
The following paragraphs discuss the format of your letter commenting on the' exam questions and your generic comment regarding True/ False questions.
a.
The format of the comments on the written exam did not adhere to the requested format.
This format was s)ecified in Attachment 4 of our July 31, 1987 letter from Mr. W. C. iehl to Mr. C. E. Larson, which formalized the examination schedule.
This Attachment will also be contained as Attachment 3 to this report.
b.
Your objection to the number of True/ False questions and their applicability toward a comprehensive exam is noted.
However, your remark about 27 True/ False items is somewhat misleading because True/ False questions only comprised 13.5 percent of the exam.
This percentage is well below the 25 percent allowable by the examiners standard NUREG 1021 ES-202.
4.
Exit Meeting The examiners met with licensee representatives (denoted in Paragraph 1) on November 6, 1987, and on November 12, 1987, at the conclusion of the examinations.
The examiners observations regarding candidate performance on the operating exams (denoted in Paragraph 2) were summarized.
The-licensee representatives acknowledged this information.

QUESTION 5.16 Prairie Island Comment:
Assuming a rod worth of 200 pcm, the prompt drop will be approximately 0.25 10 8 amps.
This drop is not readily observable to the operator.
Consequently, full credit should be given for:
Reactor power will decrease and level out'at a lower power level in the source range.
A discussion of prompt drop should not be required for full credit.
NRC Response:
Concur.
Full credit will be given proposed answer.
Prompt drop deleted from the answer key and points redistributed.
QUESTION 6.01(a)
Prairie Island Comment:
The answer key should be expanded to include additional inputs into the auto start annunciator.
Depending on selector switch )ositions, there may be an additional two (2) answers which are included witlin the answer number 1.
If the air compressor start selector switch is in "1st standby," then relay"2nd numbers 42X112-6 with 43/1st standby will actuate annunciator and if. in standby," then 42X/112-6 with 43/2nd standby will actuate annunciator due to a start from low pressure.
Also, the alarm will actuate if the thermal overloads cause the motor to trip.
The additional acceptable answers are:
5.
Running due to low air pressure and in "1st standby."
6.
Running due to low air pressure and in "2nd standby."
7.
Compressor trips on motor thermal overload.

1-ATTACHMENT 2 SENIOR REACTOR OPERATOR EXAMINATION COMMENTS AND RESOLUTIONS QUESTION 5.01(b)
Prairie Island Comment:
i At Prairie Island, some but not all startups result in initial criticality occurring in the intermediate range.
Consequently, there are two equally j
valid answers for this question.
For a startup where criticality occurs in the intermediate range, an overcompensated IR would over-predict criticality (non-conservative).
This is caused by the first data reading being too high and subsequent values not~
increasing as fast as actual neutron flux.
For a startup where criticality occurs in the source range, the overcompensation would have no effect and the answer key is correct.
Full credit should be given for either no change or.over predict, since both are correct and the cuestion specifically stated Iliat candidates should limit their answers to :
lnder predict criticality, over predict criticality or no change.
Reference:
ICRR Data Sheet, Unit I, Cycle 9, 12/17/82, Attached.
NRC Response:

The answer key has been modified to accept over predict or no change for Part b.
QUESTION 5.03(a)
Prairie Island Comment:

Do not concur.
Two filttrs in parallel allows the seal injection filter to be changed without interrupting the seal injection flow, not the manual bypass valve.
Therefore, the correct answer is FALSE.
QUESTION 6.06 Prairie Island Comment:
\\
The question does not require setpoints to be given; however, setpoints appear
~
to be required for full' credit.
The correct setpoint is -0.4 psi as opposed to a'
3 the setpoint listed of 4 psid.
Setpoint should not be required for full cred t since the question did not solicit the need to include setpoints in the answ3r.
Reference:
NF-40764-2, Attached a
NRC Response:
Concur.
The setpoint will not be raquired for full credit.
However, the utility is urged to revise their lesson plan from which this question was taken to reflect the correct setpoint.
Additionally, the question has been modified to solicit the need to include setpoints for futura v ams.

ROMION6210 Praicie Island Comment; The question does not solicit the extensive explanation that is required for full credit.
The question asks the candidate to "briefly explain the selection arocess>>
. (Include in your anwer ALL the POSSIBLE sources of power to ESF buses 15 and 16)." lhe answer key goes into great detail explaining what happens when each of the power supplies are searcied.
A brief explanc, tion of the Voltr.ge Restoring Scheme and a simple list of the power supplies should be all thW 1s requited for full credit.
Also, there seems to be some confusion
[
among the candicates as to the assumptions regarding what power sunly was wsumed to have been initially supplyiryg the ESF bus 16 and what 0
- SITE power supply was lost.
A general clarification was not made, and some candidates were told to assume IR was lost only when they questioned the proctor, and others assumed that the Cooling Tower buses along with IR were lost causing a TOTAL ioss of offsite power.
Depending on the candidate's assumption, the preferential os der of searching the buses would channe for ESF bus 16.
CT-11 and IR may be'.intercNnged depending on the assumed initial conditions,date and since the question does not imply which one(s) are/were lost, the candi may provide an answer with CT-11 and IR interchanged.
Since a clarification was not made to the entire group, either order of tne above stated search should be accepttd for full credit.
Also, the point distribution should be reconsidered since the question does not imply the detail of thr explanation as provided in the key.
NRC Response:
Partially Cencur.
The question specifically states that Unit 1 experiences a lo,ss of all offsite power which dould imply that IR and CT-11 was lost.
- Also, the quesU Un stated that with the exception of D1 supplying bus 26, all electrical lineups were normal, which means thEt IR would be initially supplying Bus 16 since it is the normal powcr supply.
Also, the voltage restoring scheme does not "sench for" IR as. t power supply to the bus, so it i

cannot be interchanged with CT-11, because CT-11 is always looked at first.
The answer key has been modified to reflect the correct order of power supplies to Bus 16 and the point distribution has been changed to recuire no explanation of additional powar* supplies, only a simple list as proposec.
QUESTION 6.11(a)
Prairie Island Comment:
- Prairie Island does not have a Channel Current Comparator.
There is a Channel Comparator and a Detector Cwrent Cotparator.
Some of the candidates may have been confused by the terminology, and credit should be givera for a correct response for either device.
The correct response for a Detector Current Comparator is:
The Detector Current Comparator is used to detect radial flux tilts by comparin average of the upper (g the input from each upper (lower) detector with thelower) detectors i
than 1.01 (2%).
l Also, the question did rot solicit more than one purpose.
Full credit for l

NRC Response:
Do not concur.
In order to explain and to show a complete' understanding of how the rod bottom lights would function to indicate this stuck rod, the setpoint for when rod bottom lights would be on, must be included in answer to receive l
full credit.
QUESTION 7.03 Prairie Island Comment:
The answers listed in the key are correct; however, other indications may be symptomatic of a failed high steam flow channel such as steam generator level deviation alarm or decreasing T if the failed channel is controlling and feedwater control is in auto.
8flsiderationshouldbegiventoother plausible answers.
NRC Response:
The questions specifically asks for initial sym3 toms (those that are immediately present) of the failed steam flow clannel, and the proposed answers would be symptoms that would be seen a short time after the channel failed, and not initially.
Therefore, the proposed answers will not be accepted.
QUESTION 7.07(b)
Prairie Island Comment:
Although an accumulator check valve leakage of 3 gpm is acceptable under TS 3.1.c.5, this amount of leakage presents problems in the accumulator. 'These valves are tested during startup, and the maximum acceptable leakage is 2.8 gpm as indicated in SP-1269.
Also, a 3 gpm in-leakage would require draining the accumulator approximately every two hours.
Frequent draining of the accumulators would dilute the boron concentration and reguire adjustments to 4
be made.
Both of these corrective actions would be required by TS 3.3.A.1.b.
l The correct response is "yes."

NRC Response:
Do not concur.
The question specifically stated to treat each case independently, and that all other operability requirements are uet. Therefore, since the leakage by itself does not violate Technical Specifications, the correct response is no.
QUESTION 7.19 Prairie Island Comment:
The answer given in the key is correct.
However, the backc;round information contained in the Westinghouse Generic ERG's under generic issues also discusses the need to trip RCP's to minimize inventory loss.

The blocked or locked components are also identified in a table located in SWI-0-3 and in a monthly surveillance that verifies the proper attachment of-blocks and locks.
Copies of the SWI-0-3 table and SP-1210 are attached.
Full credit should be given for either of these responses.
Also, dates.the word " identified" in the cuestion ma,y have misled some of the l
I candi This seems to imply:
Fow can an individual tell that a component has a lock or block attached to it? Locks and blocks have a red identifying tag attached to them.
Some candidates may respond:
By observing the red tag attached to the block or lock.
Consideration for partial credit should be given to such a response.

Purtially concur.
" Component Blocking and locking Log (Table 1) in SWI-0-3" will also be accepted as a correct response.
However, SP-1210 will.not be accepted as this only references SWI-0-3.

QUESTION 8.07 Prairie Island Comment:
A requirement to review the list of temporary memos does not exist if a red stamped copy or a controlled manual is used, because a red stamped or controlled manual would already contain the temporary memos.
The list of temporary memos needs to be consulted only if the copy is compared to the section index.
The correct answer is:
1.
Use a red stamped copy.
2.
Compare the copy with a controlled manual.
3.
Compare the copy with the section index and review the list of temporary memos.

QUESTION 8.11(a)
Prairie Island Comment:
Add as acceptable answers for determining that 4160 v ITE Bkr is racked in properly:
DC Control Power Knife Switch Closed (This will be indicated by green / red lights on)
Locking tang inserted into racking screw slot (Can be determined visually or by physical movement of racking screw)
These are simply expansions of the answer key list with derivations of acceptable answers.
Reference:
C20.15 NRC Response:
Concur.
The proposed answers will be added to the answer key as alternate correct responses for keyed answers number (a) four and five.
QUESTION 8.15 Prairie Island Comment:
The detail required in the answer is too detailed.
An acceptable answer should be:
To limit tritium releases.
Water is transferred from the CVCS monitor tank to the Spent Fuel Pit for reasons other than tritium releases.
An INPO review in 1985 recommended that 8
j
Prairie Island reduce the silica content of the Spent fuel-Pit.
To accomplish this, a reverse osmosis device was temporarily installed to process the Spent Fuel Pit water to remove the silica.
To make up borated water lost in the process, CVCS holdup tank water is transferred to the Spent Fuel Pit via the CVCS monitor tanks.
Candidates may respond to this question with a discussion of silica or other chemical contaminants.
Consideration should be given to these responses also.
Reference:
INP0 1985 E and A Report, Page 29, Attached PI Operations Note, Attached NRC Response:
Partially concur.
The answer key has been modified to accept "To limit tritium releases" as an acceptable answer.
However, alternate responses will-not be accepted since the question specifically states that the reason for transferring water from the CVCS Monitor Tanks to the Spent Fuel Pit is to curtail liquid releases, and not to make up for water lost due to the silica removal process.
QUESTION 8.18 Prairie Island Comment:
The answer given in the answer key is the preferred solution for this particular problem.
However,ajudgementmustbemadewhetherornot containment failure is imminent.
The information presented in the ?roblem is not absolutely clear on the trend of containment pressure, and t1erefore ajudgementmustbemade.
Itisnotunreasonabletojudgethatcontainmentfailureisnotimminentin this case, and therefore consideration should be given to-the following response:
1.
Evacuate all sectors out to five miles.
2.
Evacuate FGH sectors out to ten miles.
3.
Shelter remainder of plume EPZ.
4.
Activate PANS.
Reference:
F3-8.1, Page 8 of 12, Attached NRC Response:
Partially concur.
The question, as stated, indicates that containment failure is imminent.
However, since it does come down to the judgement of the Emergency Director, if it is stated in the answer that the candidates' assumption made is that containment failure is not imminent, the proposed answer will be accepted for full credit.
No changes to the answer key are necessary.

DPR-42 50-306 DPR-60 Re: COMMENTS ON NRC ADMINISTERED SRO WRITTEN EXAMINATION
Dear Mr. Wright:
Prairie Island has reviewed the Senior Reactor Operator written examination administered on November 3, 1987. General and specific comments on the examination and answer key are listed below.
Should you have any questions or comments, please contact us at (612) 388-1165.
We are pleased that the emphasis of many questions was on the basis of proce-dures and administrative requirements, rather than memorization of procedural steps not required by administrative procedures.
In addition, several system questions tested problem solving or analysis skills as opposed to testing rote memorization of facts.
We believe further improvements could be made in the written examination process.
27 questions in the examination required a true or false response.
We believe this form of questioning has limited value in a comprehensive examination, and discourage its use on our comprehensive examinations.
Our second concern is with the scope of section 8 of the exam. Although we do not take exception to most of the questions, we noted the absence of basis questions for those technical specifications that are rated the highest in NUREG-1122, Knowledge and Abilities Catalog for Nuclear Power Plant Operators:
Pressurized Water Reactors (KA catalog). We believe some questions should be selected from the highest rated knowledges in all examinations.

'~
During the' exit meeting with the examiners on November 6..1987, we discussed the philosophy of allowing equivalent.vording as acceptable responses to those listed in the answer key for all basis-type questions. We agreed that equiva-lent wording will receive full credit if the response is reasonable in'the judgment of the examiner. NSP is not writing specific comments on each of the basis-type questions that do not have equivalent wording in the answer key.
' Specific comments on. questions and the answer key are listed below:
Question 5.01 - (b)
At Prairie Island, some.but not all startups result in initial. criticality occurring in the intermediate range. Consequently. there are two equally valid answers for.this question.
For a startup where criticality. occurs in the intermediate range, an overcom-pensated IR would over-predict criticality.(non-conservative).- This is caused-by the first data reading being too high and subsequent values not increasing as fast as actual neutron flux, For a startup where criticality occurs in the source range, the overcompen-sation would have no effect and the answer key is correct.
Full credit should be given for either no change g over-predict since.both are correct and the question specifically stated that candidates should limit their answers to: Under predict criticality, over predict criticality or no change.

Question 5.03 (a)
The question asks for a brief explanation, but the answer key requires addi-tional detail not solicited in the question. We believe full credit should be given for: Decreases, because Pu e n entration increases, which has a 239 smaller beta bar than U-235.
Question 5.16 Asqming a rod worth of 200 pcm, the prompt drop will be approximately 0.25 x 10 amps. This drop is not readily observable to the operator.
Consequently, full credit should be given for: Reactor power will. decrease and level out at a lower power level in the source range. A discussion of.

O Question 6.01 (a)
The answer key should be expanded to include additional inputs into the auto start annunciator. Depending on selector switch positions, there may be an additional two (2) answers which are included within the answer number 1.
If the air compressor start selector switch is in "Ist standby", then relay numbers 42X/112-6 with 43/1st standby will actuate annunciator and if in "2nd standby", then 42X/112-6 with 43/2nd standby will actuate annunciator due to a start from low pressure. Also, the alarm will actuate if the thermal over-loads cause the motor to trip.
The additional acceptable answers are:
5.

1 Question 6.05 The answer to this question should be TRUE. Although the reference that is stated (B3-5) indicates that there is not a bypass for the seal injection filters, Flow Diagram X-ElAW-1-39 does indicate that there is a manual bypass around the seal injection filters. The other reference listed (CVCS Lesson Plan Page 10) simply states that there are two (2) filters in parallel and does not address the filter bypass.
References:
X-HlAW-1-39, Attached P8172L-001, Page 10 (CVCS Lesson Plan) Attached Question 6.06 The question does not require setpoints to be given; however, setpoints appear to be required for full credit. The correct setpoint is -0.4 psi as opposed to the setpoint listed of 4 psid.
Setpoint should not be required for full credit since the question did not solicit the need to include setpoints in the answer.
Reference:
NF-40764-2, Attached Page 3 of 7 w ___________
Question 6.09 The answer should be TRUE. The reference stated (DG Lesson Plan, Page 19) does not contain the answer listed in the answer key. Page 18 of the same reference does state that D1'is normally supplied by 11 DC Panel or 21 DC Panel as the backup via a manual transfer. Page 19 of the reference material is regarding D2, not D1, as is asked in the question.
Reference:
P8186L-004, Page 18 (Diesel Generator Lesson Plan), Attached Question 6.10 The question does not solicit the extensive explanation that is required for full credit. The question asks the candidate to "briefly explain the selection process..........(Include in your answer ALL the POSSIBLE sources of power to ESF buses 15 AND 16)".
The answer key goes into great detail explain-ing what happens when each of the power supplies are searched. A brief explanation of the Voltage Restoring Scheme and a simple list of the power supplies should be all that is required for full credit.
Also, there seems to be some confusion among the candidates as to the assumptions regarding what power supply was assumed to have been initially supplying ESF bus 16 and what 0FFSITE power supply was lost. A general. clarification was not made, and some candidates were told to assume IR was lost only when they questioned the proctor, and others assumed that the Cooling Tower buses along with IR were lost causing a TOTAL loss of offsite power. Depending on the candidate's assumption, the preferential order of searching the buses would change for ESF bus 16.
CT-11 and IR may be interchanged depending on the assumed initial conditions, and since the question does not imply which one(s) are/were lost, the candidate may provide en answer with CT-11 and IR interchanged. Since a clarification was not made to the entire group, either order of the above stated search should be accepted for full credit. Also, the point distri-bution should be reconsidered since the question does not imply the detail of the explanation as provided in the key.
Question 6.11 (a)
Prairie Island does not have a Channel Current Comparator.
There is a Channel Compriator and a Detector Current Comparator. Some of the candidates may have been confused by the terminology, and credit should be given for a correct response for either device. The correct response for a Detector Current Comparator is: The Detector Current Comparator is used to detect radial flux l
tilts by comparing the input.from each upper (lower) detector with the average of the upper (lower) detectors, and alarming if the ratio is greater than 1.02 (2%).
Also, the question did not solicit more than one purpose.
Full credit for Channel Comparator should be given for either: To detect radial flux tilts cy; to detect faulty PR channels.

The question does not solicit setpoints as part of the response. The setpoint should not be required as part of a full credit response.
Question 7.03 The answers listed in the key are correct; however, other indications may be symptomatic of a failed high steam flow channel such as steam generator level deviation alarm or decreasing T if the failed channel is controlling and feedwater control is in auto. doEsideration should be given to other plausible answers.
Question 7.07 (b)
Although an accumulator check valve leakage of 3 gpm is acceptable under TS 3.1.c.5, this amount of leakage presents problems in the accumulator.
These valves are tested during startup, and the maximum acceptable leakage is 2.8 gpm as indicated in SP-1269. Also, a 3 gpm in-leakage would require draining the accumulator approximately every two hours. Frequent draining of the accumulators would dilute the boron concentration and require adjustments to be made. Both of these corrective actions would be required by TS 3.3.A.1.b.
The correct response is "yes".

Question 7.19 The answer given in the key is correct. However, the background information contained in the Westinghouse Generic ERG's under generic issuer also discusses the need to trip RCP's to minimize inventory loss.

The blocked or locked components are also identified in a table located in SWI-0-3 and in a monthly surveillance that verifies the proper attachment of blocks and locks.
Copies of the SWI-0-3 table and SP-1210 are attached.
Full credit should be given for either of these responses.
Also, the word " identified" in the question may have misled some of the candidates. This seems to imply:
has a lock or block attached to it?How can an individual tell that a component Locks and blocks have a red identifying tag attached to them. Some candidates may respond:
By observing the red tag attached to the block or lock.
Consideration for partial credit should be given to such a response.
Reference:
SWI-0-3, Table 1 and SP-1210, Attached Question 8.07 A requirement to review the list of temporary memos does not exist if a red stamped copy or a controlled manual is used, because a red stamped or controlled manual vould already contain the temporary memos.
The list of temporary memos needs to be consulted only if the copy is compared to the section index.
The correct answer is:
1.
Use a red stamped copy.
2.

Water is transferred-from the CVCS monitor tank to the Spent Fuel Pit for reasons other than tritium releases. An INP0 review in 1985 recommended that Prairie Island reduce the silica content of the Spent Fuel Pit. To accomplish-this, a reverse osmosis device was temporarily installed to process the Spent Fuel Pit water to remove the silica.
To make up borated water lost.in the process, CVCS holdup tank water is transferred to the Spent Fuel Pit via.the CVCS monitor tanks. Candidates may respond to this question with a discussion of silica or other chemical contaminants. Consideration should be given to these responses alro.

Question 8.18 The answer given in the answer key is the preferred solution for this particular problem. However, a judgment must be made whether or not contain-ment failure is imminent. The information presented in the problem is not I
absolutely clear on the trend of containment pressure, and therefore a judgment must be made.
It is not unreasonable to judge that containment failure is not imminent in this case, and therefore consideration should be given to the following response:
1.
Evacuate all sectors out to five miles.
2.
Evacuate FGH sectors out to ten miles.
3.
Shelter remainder of plume EPZ.
4.

SHIFT SUPERVISOR 1.0 PURPOSE The purpose of this procedure is to provide guidelines to establish the basis upon which protective action recommendations i
are to be made to the offsite authorities responsible for i
implementing such actions.
2.0 APPLICABILITY This instruction shall apply to the on-shift Shift Supervisor /
Emergency Director.
3.0 PRECAUTIONS 3.1 Initiation of protective actions for offsite areas is the responsibility of the State of Minnesota and the State of Wisconsin.
If it is determined, by the Emergency Director, that, immediate protective actions are' required, and the State EOC's are not activated, the Emergency Director SHALL authorize such recommendations to be made directly to the local authorities.
Once the State EOC's are activated, all protective action d
recommendations SHALL be made to th'e State EOC's.
3.2 The protective actions in this procedure are limited to protective actions for minimizing the exposure of the public within the 10 mile plume exposure pathway, to external and internal radiation exposure from the passage or inhalation of the radioactive plume.
Other protective actions for minimizing the exposure of the population within the ingestion exposure pathway should be determined and implemented by the appropriate state authorities.
4.0 RESPONSIBILITIES l

GENERATING PLANT PROCEDURES NORTHERN STATES POWER COMPANY Number: F3-8.1 Rev: 1 5.0 DEFINITIONS 5.1 Plume Exposure Pathway, The 10 mile radius around Prairie Island defined for the short term " plume exposure".
The principal exposure sources from this. pathway are:
(a) whole body external exposure to gamma radiation from the plume and from.
1 deposited materials and (b) inhalation exposure from the The duration of principal passing radioactive plume.
potential exposures could range'in length from hours to days.
5.2 Plume Emergency Planning Zone (EPZ)
A defined area around:the plant to facilitate emergency planning by state and local authorities, to assure that and effective actions are taken to protect the prompt public in the event of a release of radioactive material.
It is defined for:
Plume Exposure Pathway a.
i A 10 mile radius around the plant where the principal exposure source.is: (1) whole body exposure to gamma from the plume and from deposited material; and (2) inhalation exposure from the passing radioactive plume (Short-Term Exposure).
b.
Ingestion Exposure Pathway A 50 mile radius around the plant where the principal exposure would be from the. ingestion of contaminated' water or foods such as, milk or fresh vegetables (Long Term Exposure).
5.3 Projected Dose An estimate of the radiation dose which affected individuals could potentially receive if protective actions are not taken.
5.4 Protective Action

5.,6 Public Alert and Notification System (PANS)
(1)
The Public Alert and Notification System (PANS) is used to alert the public within the 10 mile Emergency Planning Zone, of'an emergency-condition at Prairie Island.
Once alerted, the public should then turn to local commercial broadcast messages fgr specific protective action instructions.
The Public Alert and Notification System surrounding Prairie Island consists of the following:
a.
Fixed Sirens for'100% coverage throughout the 5 mile zone =and in population centers in the 5-10 mile zone.
b.
Emergency vehicles with sirens and public
~
address in the 5-10 mile areas not covered by fixed sirens.
c.
National Oceanic and Atmospheric Administration (NOAA) L:tivated tone alert radios in institutional,. educational,.and commercial facilities.
d.
The-Emergency Broadcast System (EBS) which has access to television and' radio stations.within 4
the area.
1 (2)
Activation of the Public Alert' and Notification System should be recommended if any protective action such as sheltering or evacuation has been recommended for the public within all..or a portion of the 10 mile Emergency Planning Zone.
5.7 Designation of Affected Areas The designation of the area requiring protective actions is going to depend on the nature and extent of the 1
incident and existing meteorological conditions.
1 Generally, the affected area should resemble a keyhole, consisting of a 360* area surrounding the facility, 7
out to a distance of about two to'five miles and I\\

include'one-sector on either side of-the affected sector, out.to a distance, as. determined by the Protective Action Guides.
Initial efforts for protective actions-should'be in the downwind direction.
O PROCEDURE 6.1 Protective Action Recommendations 6.1.1 If a " GENERAL EMERGENCY" has been declared,.
refer to Figure 2, " GENERAL EMERGENCY PROTECTIVE ACTION GUIDELINES".for immediate protective action recommendations.
NOTE:
DO NOT DELAY protective action recommendations during General' Emergency conditions.
Figure 2 contains protective action' recommendations for General Emergency conditions' based on Control Room' indications and requires no dose proj ec tions ~.

ANSWER 5.06 (2.00)
Q-dot = m-dot delta-h (0.5)
M-dot = 15.0 E 6 lbm/hr.
h-steam = h g at 1025 psia =.1192 BTU /lbm (0,5) h-feed = h-f at 428 degreen F = 405 BTU /lbm OR
= h-f at 1025 psia - (c-p x delta 1) 402 BTU /lbm
= 546 - (1.2 x (548-428)
=
(400-430 BTU /lbm acceptable)
(0.5)
Therefore:
0-dot = 15 E 6 x (1192-402) ~ BTU /hr 1.2 E 10 BTU /hr (0.3)
=
Converting to MW 0-dot = 1.2 E 10 BTU /nr x (1 MW/3.41 E 6 BTU /hr)
= 3470 MW (0.2) (3350-3500 MW acceptable)

ANSWER 5.08 (2.00)
Rod worth is a f unction of the,mlativa f1un difference between the 41un at the rod tip and the core average flux.
(1.0)
When a rod is stuck out with all other rods inserted, that rod " sees" a much higher flux than the rest of the core, and could be worth 1000 pcm (0.5)
If a rod is dropped, that rod depresses the flux in the area it is in relative to the rest of the core, and would be worth only about 2OO'pcm.
