Docket No. 50-29 Yankee Atomic Electric Company ATTN: Mr. Robert H. Groce Licensing Engineer i 20 Turnpike Road Westboro, Massachusetts 01581 Gentlemen: -

As a result.of our evaluation of the Yankee-Rowe Fire Protection Program and our fire protection site visit of the facility from September 25 through September 28, 1978, we have developed positions on the outstanding issues. These positions were discussed in detail with Mr. L. H. Heider, Assistant Vice President, Engineering and Operations, on September 28, 1978. During this meeting representatives of Yankee Atomic Electric Company (YAEC) agreed with several of our positions.

Enclosure I lists each staff position and identifies your position on each, i.e. accepted, rejected or deferred for further study.

Enclosure I also identifies by marginal notations the status of staff positions accepted by YAEC. The status is based on information your representative provided during a telephone discussion on October 2, 1978.

Yankee-Rowe was shutdown on October 21, 1978, for refueling with Core l 14. We understand that you are scheduled to resume operations by

, December 1, 1978. Prior to the October 21, 1978, facility shutdown you had taken appropriate actions to improve your ability to mitigate

the consequences of a fire under existing conditions, including the l use of an increased number of fire brigade personnel. We found those actions acceptable for the short period of time until facility shutdown because of the low probability of a severe fire during this time period.

For the interim period following resumption of facility operations from the current refueling outage until the final fire protection modifications identified in Enclosure I are completed, we believe that the fire brigade should consist of seven trained members. The basis for this position is given in the draft report, Enclosure II, from our consultant on manual fire fighting. We have reviewed your basis for the adequacy of the existing three man fire brigade, provided in your letters dated December 14, 1977 and June 26, 1978. We have concluded that you had not adequately addressed the following items:

781113033'I i

? ,

y-

f 4

Yankee Atomic' Electric Company November 1,1978 1.. The: operations which must be performed to control and extinguish potential fires.

2. The availability of equipment to control and extinguish potential fires. '

3. -The adequacy of the training for fire brigade members and backup support such as onsite security personnel and

_0 assistance from offsite groups.

Please be prepared to resp'ond to the concerns, identified by our consultant in Enclosure II, during a meeting with the NRC in our offices on November 8,1978. You should also be prepared to address the above three items'and to provide the qualifications of those individuals who .have- established the size and training of the fire brigade. The purpose of the meeting .is to resolve the open issues relating to the fire brigade and to the shutdown capability resulting from modifications being implemented during the current refueling outage.

Please. confirm that: (1) Enclosure I correctly represents YAEC's responses to the NRC staff positions'and (2)'your responses to the

. unresolved NRC' staff positions will be provided by December 1,1978.

Sincerely, Ydh Ay Dennis L. Ziemann, Chief

. 1.1 Yankee Atomic Electric Com; hereafter referred to as v.! 7 l i,j.j YAEC, Yankee Rowe facility, hereafter referred to as YR, is I.,f located in the town of Rowe, Massachusetts on the east bank of N.; the Deerfield River's Sherman Pond, approximately 20 miles north

: vest of Greenfield, Massachusetts. Malling address for YAEC is

[.) 20 Turnpike Road, Westborough, Ma. 01581.  ;

V's .

Itinerary. for the site visit to YR was to leave Deerfield l ,,Jj 1.2 j Beach, F1. at 0530 on September 25, 1978 proceeding to Fort

. Lauderdale: International Airport for a flight to Hartford, Conn.

t via Atlanta, Georgia.

DRAFT-10/2/78 YANKEE ROHE Due to a mechanical problem with the aircraf t at Atlanta, the connecting flight was delayed for approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 15 minutes, setting back my arrival in Hartford to approximately 1245.

On arrival at Hartford, I was met by L. Derderian, the other two members of the team had gone ahead to meet with the YAEC guide at the scheduled time. Under the circumstances it was necessary to rent a car for transportation from Hartford, Conn. to Rowe, Ma. which was used during the site visit for transportation to and from the plant.

I arrived at the plant site at approximately 1430 to begin the required processing for both security and health physics reasons.  ;

Yankee R6we's requirecent that all visitors to the plant receive a total body count and complete the respiratcr test prior to entry into the controlled areas resulted in an entry meeting that I

1 was held.by the N.R.C. team leader while other members of the team were being processed.

}

l'. 3 At.the completion of the processing and entry meeting, the

'I team began the site visit with a walk-through of the safety i

related areas of the plant as a form of introduction to the facility.

YAIC assigned Ed. Sawyer, Fire Protection Coordinator for YAEC, Ed May, Y5' Fire Protection Coordinator, J. Staub, YA technical e

l l

1.4 On the days following our format was to arrive at the i

plant site at 0730, advise and discuss with the plant personnel l f any questions or positions developed as a result of our obser- )

I j vations from the previous day, then continue with the site

' review throughout th6 day. Our site visit concluded each day

{

at approximately 1630. On return to our motel, the team would

] ,

meet' to discuss and review the day's observations and develop positions to be presented the following day and at the exit meeting.

l

} 15 The exit meeting was held on September 28, 1978 beginning

, at approximately 0930 attended by 15 members of YAEC staff and 9 members of the N.R.C.

1 f In addition to the N.R.C. team members previously listed, the

exit meeting was attended by R. L. Ferguson, Section Leader, NRC-DOR-PSB, D. L. Ziemann, NRC-DOR-ORB 2, A. Burger, DOR-OP32,

.', R. Paolino, NRC-I & E and W. Lazarus, NRC-I & E.

as an observer primarily to prepare for his assignment as one of the NRC-I & E individuals who will be conductihg the F.E. A. I site reviews and who will be responsible for the administrative l controls portion of the review at YR.

, In tb.is capacity he accompanied this consultant during my interviews with plant personnel regarding the fire protection i

i organization, fire brigade training and administrative controls

! areas. He also accompanied me on my visits to the two (2) off-site fire suppression assistance forces at Rowe and Monroe Bridge. I made every attempt to keep Mr. Paolino advised of the data and informe. tion necessary to carry out these areas of the site visit and review.

\

Those members of YAEC staff that we' had contact with during our g site visit were cooperative and helpful in aiding us to complete our evaluation. In turn every effort was made to explain our concerns and positions as we conducted the visit.

I This consultant worked closely with the team end other N.R.C.

representatives making suggestions, giving advice and adding input to positions and concerns related to '.1anual fire suppression.

2. FIRE PROTECTION ORGANIZATION 2.1 The fire protection organization for YR is established by the fire protection program developed by YAEC for all their i

-o--...,-,a-5- YAN12E BOWE facilities and is well defined. j l

2.1.1 Organization charts provided as a part of the fire protection program clearly illustrate the management authority 1

and responsibility for both the on-site and off-site-organization. I 2.1.2 Off-site organizational responsibility for fire protection is under the direct authority of the Assistant Vice President of Operations'who in turn delegates this responsibility to the YAEC Fire Protection Coordinator.

The Fire Protection Coordinator meets all the requirecents for his position with the exception of the number of years (3) in

, responsible charge of fire protection, having at present only i two years in this capacity.

2.1 3 On-site the fire protection program is the responsibility of the Plant Superintendent who delegates the direct responsi-bility to TAPS and thereby to the plant fire protection coordinator in the TAPS department.

2.1.4 The plant fire protection coordinator can be considered the plant fire marshal beins responsible for all fire protection except fire fighting. It.is his responsibility to see that the required fire prevention and fire protection inspections are carried out by the responsible YR department or division.

While YR does not have a specific fire prevention committee as such, fire prevention and protection matters are covered as a required portion of the facility safety committee meetings.

4 2.1 5 Responsibility for inspection, testing and maintenance of fire protection equipment is c1carly defined in the a&nin-1 istrative procedure developed for specific areas of the plant.

Coordination and follow up where necessary are under the YR J Fire Protection Coordinator.

2.2 Adecuacy of Fire Protedtion Organization i

! 2.2.1 After careful review of the information contained in  !

l YAEC letter to V. Stello, dated May 10, 1978 and an evaluation of the administrative procedures related to the fire protection i 4

organization, it is the conclusion of this consultant that the fire protection organization for YR is fully adequate and meets the requirements of the N.R.C. guidelines and appendix A to i

BTP APCSB 9 51.

23 Modifications and Recommendations 231 None at this time. 4 3 FIRE BRIGADE l 31 The fire brigade for YR is establirhed under the plant emergency plan. While there is no organizational chart showing  !

l i

MMAF8-l@/2/o/@

YANKEE ROJE the command structure AP-2001 establishes the Shift Supervisor as the brigade leader and assigns conmand responsibility to the remaining members in descending order matching their plant  ;

i operations functions.

j As stated in YAEC's response letter to D. L. Ziemann, Chief l' '

ORB-2 dated August 14, 1978, the fire brigade at YR will be -

l made up of three fully trained fire fighting personne1 including 3

the Shift Supervisor as the fire brigade leader and two additional-support people whose primary responsibility will be to support the fire brigade. i YAEC has proposed the above for a11' shifts including back shifts 7

and holidays. However during the normal day shift there will be additional trained personnel on duty who will assist the fire l

, brigade when necessary. l I

i*

3 1.1 The position of direct rdsponsibility for the fire brigr.de operations during a fire emergency is the Shift Superintendent. {

l Overall responsibility for any emergency rests with the YR Emergency Coordinator.

? i leader following his arrival at the fire.

313 Under normal plant conditions the regular responsibilities of the fire brigade members do not conflict with their fire i

, brigade assignment.

3.1.4 All fire brigade members qualifications include satis-factory completion of annual medical / physical examinations for

, performing strenuous activity. (Ret YAEC letter to USNRC dated May 10, 1978.)

l l 315 It is the intent of YR to schedule fire brigade meetings as part of the required tra!.ning and drill schedule for the fire brigade. These are intended to be held on each shift by the fire brigade leader.

32 Adecuacy of Fire Bricade l

e i

i 3 2.1 The fire brigade organization as stipulated in YAEC I

letter to the N.R.C. dated August 14, 1978 is inadequate in three areas.

, One concern is that YAEC states that the brigade will consist l-3 of "three fully trained fire fighting personnel" and "on each J

shift two (2) support personnel". "These support personnel will receive the training necessary to perform their support roles only." _  !

Inasmuch as all members of a fire brigade should be fully trained 1

]- as fire fighters, this position is unacceptable.

~

l, 3 Ni5ETdE ]

A second area of concern is that YAEC states that one of the j three fully trained personnel vill be the Shift Supervisor as j brigade leader. In view of the need for the Shift Supervisor  !

be I to/available to the control room for decisions relating to the

4.1.2 The ac' ual training is conducted by the YR Training Coordinator and Assistant Training Coordinator. Their qualifi-cations to conduct fire brigade training are minimal, primarily based upon qualification as an instructor, some training at the Niagra-Mohawk training site and service as a volunteer fire fighter.

• indicates YAEC commitment to the position or to the intent.

I DRAFT-10/2/78 YANKEE ROWE 4.1 3 Training .t3 scheduled on a quarterly basis and is designed to repeat the classroom sessions over a two year period.

Hands on type training is conducted on-site on an annual basis, consisting of the use of extinguishers, operating manual hose streams on oil fires and simulated fire fighting conditions that could occur in the plant.

The training tapes prepared by ITC are used as the basis for the fire brigade training along with personal instruction by the Training Coordinator.

4.1.4 Fire brigade leaders and other members of the fire brigade who may have to assume command of the brigade do not receive any specialized training in leadership and command tactics.

4.1.5 Records of training are kept both in the individuals' file and in the general training file showing all participants.

Training records show the date, time allocated, subject coverbd and personnel attendance.

4.1.6 Fire brigade meetings are being scheduled for the future and are to be conducted by the fire brigade leader for each of the operating shifts.

1 i 5 OFF-SITE FIRE SUPPPISSION ASSISTANCE 51 Yankee Rowe nuclear power plant is located in the town j limits of the town of Rowe, Massachusetts and is entitled to

fire protection from the Rowe Volunteer Fire Department.

Fire protection is also provided by the Monroe Volunteer Fire j Department on an agreement basis and as part of the ara 1 fire mutual aid.

Both Rowe and Monroe are called any time that off-site assistance is deemed necessary by the fire brigade leader.

5 1.1 Both Rowe and Monroe are fully volunteer fire departments.

The roster for Rowe totals approximately 40 members, of which 20 are considered active members.

The Monroe rester totals 7 members, all are considered active.

s a

UKAFT-10/2/yo i, , ~16- YANKEE RO'dE f

5 1.2 The qualifications of the fire chiefs of both Rowe and Monroe are limited to their personal experience as volunteer fire fighters with cinimal formal training.

The Rowe chief has been a volunteer for 30 years and has a total

• of 10 years as chief over three broken terms. The Rove chief f

l 1s elected by the membership each year without limitation. He in turn selects his officers who serve at the pleasure of the chief. There are no specific qualifications or standards for becoming an officer of the RVFD.

The Monroe chief has been a volunteer for 10 years and has been chief for the past 2 years. He is appointed by the select =en I and serves at their pleasure. He in turn selects his officers much the same as Rowe. Fire fighters are elected by the fire l

l companies following application and there are no specific j requirements regarding training or other qualifications.

Consideration must be given to the fact that Rowe and Monroe are communities of approximately 300 individuals; therefore the volunteer fire co::.panies are forced to take anyone who applies.

513 Rove VFD does not have specific training requirements.

Meetings and training are held whenever the chief decides to c all one. Usually coetings are held mohthly except during the s u:nmer. '

I

unAr 1-1U/ d/ '/o d e YAIUZE ROWE Monroe VFD has required monthly meeting / training sessions year round.

Neither RVFD or MVFD have any kind of femal training requirements.

Neither department requires its personnel to attend training schools and neither takes much advantage of the programs offered by the Massachusetts fire academy.

5 1.1+ The Rowe V.F.D. has two pumper / tankers, one 750 GPM (1971) and one 500 GPM (1962) both of 'which are reasonably equipped

. for rural fire fighting.

Monroe has one pumpor/ tanker, a 750 GPM (1960) which is also t

reasonably equipped for rural fire fighting.

! 5.1 5 Special equipment that would be valuable to the plant i

consists of a large supply of fire fighting foams at the Rowe V.F.D. , beyond this neither fire company has any special equipment.

5 1.6 Monroe V.F.D's fire station is located approximately i

1 5 miles from the plant. Response is limited to one access road that is narrow and often congested at one point by inductrial I trucking operations.

G Response ti=e, without obstructions of any sort, is estimated to be 10 minutes. Personnel availcble during the work day may be limited to something less than the seven active men.

Manpower available during the nornal work day is estimated at ten men.

Rowe's active volunteers are each provided with a radio call

} system at their homes. Monroe V.F.D. depends on a factory

steam whistle to alert its members.

517 Command authority for fire fighting at the plant site rests with the plant fire brigade leader. This is clearly understood by both Rowe and Monroe chiefs.

5.1.8 Joint training between the off-site fire companies and the plant fire brigade has been minimal, for the most part j consisting of annual familiarization visits to the plant.

l 519 Both the Bowe and Monroe V.F.D.'s belong to the tri-state fire mutual aid system that encompasses a 25 mile radius.

There is an automatic move up system employed which would provide additional apparatus and manpower if necessary.

52 Adecuacy of Off-Site Fire S'ionression Assistance 5.2.1 The Rowe ar.d Monroe Volunteer Fir a Departments are very typical of remote rural volunteer fire c.*mpanies. They are minically adequate to protect their commnities; however they

are considered inadequate as related tc providing viable fire suppression assistance to the YR fire br.gade.

53 Modifications and Recommendations 5 3.1 YAEC should encourage and support the training of the off-site suppression forces both in the areas of improved internal training, training by the Massachusetts fire academy and by providing training facilities at the plant site for the fire companies to use and where joint fire brigade /off-site suppression forces training can be conducted.

532 YR should make every possible effort to encourage the off-site fire suppression forces to participate in joint training

,! and drills at the plant.

l 533 As soon as the pre-fire strategies are developed for the safety related areas of the plant, the off-site assistance i forces should be advised of the strategies and invited to participate in test drills to check the validity of the strategies.

sideration must be given to the consequences of a fire in any l area of:the plant regardless of the safety relation of the specific; area.
