VERMONT YANKEE NUCLEAR POWER CORPORATION ,

LRS CONSULTANTS TEAM VISIT.#3-83 OCT. 12-14,1983 .

s

. LRS . Consultants visited Vermont Yankee Nuclear Power Corpora-tion on Oct. 12-14 as a routine assessment of. its management and operations. Priority attention was given to in-depth interviews with .

top-level management personnel at the plant with emphasis on com- -

munications, training and radiation protection.

Findings and recommendations for various topics are given in the following sections.

Radiation Protection 7

As mentioned in our last report the 1983 outage might result in the accumulation of about 1,500 person-rem for the collective radiation exposure of VY and contractor personnel. It appears that this projection is correct and that the 1983 worker dose will not exceed 1,600 person-rem, provided that there are no additional outages involving significant exposure. The 1983 total represents an historic high for the plant.

CHART A illustrates the collective radiation worker exposure both for VY and Boiling Water Reactors (BWR's) from 1976 to 1982.

Following the Three Mile Island Unit-2 accident in March 1979 the NRC requirements for equipment modification caused .an increase in collective radiation exposure. The 1981-1982 downtren,d was steeper for. VY than for other BWR's.

Successful decontamination of the VY recirculation lines -

(see Section on Decontamination) greately reduced worker exposure

~

in the 1983 outage, especially for the pipe overlay welds. The use of remotely operated welding also served to reduce worker exposure.

Otherwise, the outage exposure would have been.very much higher.

Averaged over years.of operation since start-up, VY annual exposure has been 491 person-rem through 1982. As shcan in CHART A, the industry average is 80 per cent higher than the VY annual

average. The average annual. exposure per VY worker has been 0.51 rem as compared with 0.78 rem for other BWR workers.

,g, The collective radiation exposure for BWR units is shown in CHART B. Vernont Yankee ranked lowest among all BWR units with a value of 205 person-rem versus 1,030 person-rem averaged for other ,

BWR's.

CHART C represents person-rem' data averaged over the length 5f plant operations from start-up through th,e end of 1982. Overall, 164 reactor-years of operatio'n resulted in the accumulation of 136,570 person-rem. Vermont Yankee ranked fourth among BWR's in terms of. lowest person-rem. ,

While the person-rem is important as the unit of collective radiation exposure, the dose distribution among workers is also very significant. CHART D illustrates how radiation exposure above 0.1 rem per year was distributed among BWR workers.in 1982. The data pertain to 22,291 workers and produce an average of 891 workers for each BWR unit. The 320 VY workers exposed above the 0.1 rem level did not incur a single exposure above 2.0 rem. This excellent control of exposure is commendable in view of the fact that almost three times as m'any workers at other BWR units were exposed above the 0.1 rem level. About 18 per cent of these workers exceeded 2 rem. ,The extensive VY outage work caused a few workers to exceed 2 rem in 1983 but none received more than 4 rem.

Despite the relatively high collective dose accumulated in 1983 VY management has acted effectively to implement its ALARA (As low As Reasonably Achievable) policy and to safeguard worker health.

Perspective on Radiation Risk Given the nature of radiation risks and widespread media attention to them, it is understandable that some workers are con-cerned about these risks. VY management is encouraged to continu,e .

timely worker communication on the health risks of ionizing radia-tion. These risks are not unique to nuclear power and they need to be placed in perspective. For example, in 1982 a total of 129,275 U.S. workers were monitored for exposure to radiation at nuclear sites. More than half of these workers received less than

=3= q l

0.1 rem; this is the amount of radiation dose received by all U.S. l citizens as a result of exposure to natural radiation. The entire ' '

l nuclear work force rece'ived a total of 52,190 person-rem in 1982.

This risk may be compared to that received by over 4 million Ameri-cans each year as a result of exposbre to a,' single type of diagnos-r l

i tic x-ray examination, namely, fh'e lumbar / spinal x-rays. This exam-ination, common to heavy industry pre-employment requirements, in-

'volves about' O.4 rem of radiation dose per inIdividual. The collec-tive radiation exposure for such annual x-ray examinations amounts to 1.6 million person-rem. This is nore than 30 times the collec-tive exposure received by all nuclear plant workers in 1982.

It is recommended that VY workers be given periodic updates on the health ef fects of ionizing radiation, including perspective on radiation risk. This may be done as part of the annual General Employee Training (GET) program (See Section on Training).

Female Worker Radiation Exposure Policy VY management provides female workers with accurate informa-tion regarding procedures to be followed,when they have access to

~

radiciogical1y contro11dd areas." Training is given in accordance with U.S. NRC Regulatory Guide 8.13 based on recon.acndations of

~

the International Commission on Radiological Protection for the protection of the unborn child. The embryo is recognized as being sensitive to ionizing radiation and exposure is restricted to a maximum of 0.5 rem for the total period of pregnancy.

At present female workers at VY are given a dose allocation of 0.6 rem per week. While it is recognized that there is a daily posting of exposures during outages when exposures are greatest, it is still possible that a female might exceed the 0,5 rem guide- ,

line of the ICRP. It is suggested that VY management should revise -

its dose allocation policy accordingly.

VY policy provides females who become pregnant with further instruction about radiation risks for the unborn child. Further exposure of such a female is handled on a case by case basis. In no case is a pregant woman's exposure allowed to approach 0.5 rem.

Indeed, management has restricted such workers from further access

c

4

to radiologically controlled areas until pregnancy has been con- -

cluded. This conservative policy is prudent. It is recommended that the VY Health Physics Review Board formalize recommendations for policy on the exposure .of female workers to ionizing radiation.

llealth Physics Review Board , . . .

Since its creation a year go the Health Physics Review Board has held four meetings but it has not issued any recommenda-

  • tions. Understandably, a newly organized technical body experiences

" start-up" difficulties, but it appears that sufficient tine has elapsed for publication of substantive reviews and recommendations.

~

The Board is urged to proceed expeditiously with such activities.

!I Radioactive Contamination Since the previous visit there has been some concern that alpha particle contamination might be present in significant levels at certain BWR plants. Careful and repeated smear samples were taken at various VY plant locations. Assays of these samples showed no evidence of significant ' alpha activity. Work done by the Ya'nkee At'omic Mobile Laboratory was verified by an NRC con-tractor assay.

The extensive outage and demanding drywell operations posed the potential for uptake of radioactivity by plant workers. Such uptake proved to be minimal as evidenced by the low frequency of personnel contamination cases and by routine whole body counting data. Nonetheless, increased attention is urged to insure proper frisking by all workers.

Decontamination in the Drywell Up to the time of the 1983 outage accunulation of radioac-tive deposits in drywell piping, especially in the recirculation line, cau'ed s a continuing increase in drywell radiation levels.

This is illustrated in CHART E where the build-up of contact radiation levels in the recirculation system piping reached a naximum of 1.4 r per hour. The extensive drywell work in the 1983

y,,

~

' -5= ,

outage would have involved very high. collective radiation exposures and additional manpower had the drywell radiation levels remained unchanged. Fortunately, management ha'd planned for decontamination of the piping prior tocthe outage _. A.first decontamination did not 2

reduce the radiation levels but a second effort produced a drama-tic drop as shown in the chart. Without this.' successful decontam-ination the collective exposure for the outage we.uld have been

. very high. A post-outage drywell measurement showed a small increase in radiation level which is being tracked to determine its future -

course.

There has been concern that older nuclear plants might become increasingly radioactive and result in corresponding in-creases in worker exposure. VY's success in decontamination shows that t.his need not be the case.

Environmental Contamination

,.- ,hDn This summer [ portable concentrations 'of cobalt-60 were found in river sediments a't 'a ' point where' the orth branch of the VY sewer system discharges into the Connecticut River. It appears that this Co-60 originates from venting of the Turbine Building.

Radioactivity is deposited on roof gravel and subsequently Co-60 is sluiced off by rain and is carried to the river.

A number of fixes appear feasible to prevent recurrence of this discharge of radioactivity to the river sediment. As it is, the concentration of Co-60 and the absence of any direct pathway to man are such that Co-60 in the sediments does not pose a signi-ficant risk to the public health.

Training A' lengthy interview was conducted with the newly appointed' Training Supervisor. He is very plant knowledgeable an' d enjoys good rapport with the workers. His plans to reorganize training appear to be both sound and realistic. However, the recent loss of professional personnel from the Training Department will be a challenge to the supervisor's plens.

The Department's complement is low relative to some other facilities and licensed operator training is dependent on con-2

=6= .

. tractor instruction.'The present work load for VY trainers will un- .

doubtedly increase as both NRC and INPO (Institute of Nuclear Power Operations) requirements impose greater demands, especially in 4

training non-licensed operators'.. In addition, new nuclear plants y: . .

. .' coming on line will increase the' de' mand for' experienced trainers and vill impose a burden on an already tight' market for such in-i l' dividuals.; Priority should be assigned to recruiting qualified personnel to strengthen VY's training operation. .

The .GET video tape umde by a Vermont contractor for indoc- -

trination of all radiation workers is a professionally executed I instructional aid. It introduces workers to procedures and precau-tions to be followed when working in radiologically controlled

, areas. However, it is recommended that health effects of radiation

. risks' be given m' ore attention in GET training. ,

Management Training and Communication P -Top management at Vermont Yankee is giving priority atten- 7

. tion to upgrading management capability of key per9onnel in plant operations. Emphasis is being placed on:

h .a Insurin'g highly reliable and safe' plant operation b- Prompt recognition of off-norum1 plant conditions c- Improved on-shift communications between management and operations d- Improved definition of the management responsbilities of

~

i shift supervisors as well as other : personnel.

. Interviews with operations personnel showed that some in-dividuals are concerned about the ever' increasingly complex pro-Leedures ' for plant. operations. Licensed operators are deeply con- - '

scious of their license responsibilities. Some operators 'are

. " control room oriented" and are highly attuned to technical developments; they may be.less aware of the:public view of unusual event's occurring at nuclear plants. It is understandable that their first priority must always be the safe operation of

~

.the plant and management of a transient imposes' considerable demands on them. Now that the wide spectrum of; unusual events -

hppears to be adequately addressed, what remains is to improve man-agement skills of key personnel. An important factor herE is devel-opment of smooth interfaces in management / operations communications. , ,

Out ide consultants are being 'used to give seminars to shif t super- ,

visors and senior control room operators in control room manhgement during emergencies. In addition, a managenent, skills course is being formalized.

There has been good response to a management initiative in improving communications. Monthly meetings have been conducted .

with small groups of plant personnel and top management at the Brattleboro office. The purpose is to insure a candid discussion of common problems. This is believed to be a salutary development'.

It appears that management has set in motion a program to improve management skills that will substantially upgrade the per-formance of plant personnel.
