Docket No. 50-352 - OL A J

ASLBP No. 87-550-03gA AUG 31 P3 :2i SUPPLEMENT TO PETITIONER'S RESPONSE OF 7/2/87 TO THE BOARD'S NOTICE OF.; HEARING

.AND ORDER OF 7/29/87 A:

s The petitioner,R.L. Anthony hereby submits the following contentions in opposition to the granting of a license amendment to the Technical Specifications

,for Limerick Unit 1 in the matter of radioactive iodine spikes.

1. We refer to and incorporate all of the points'in our previous submissions.

On pages 1 and 2 of our 7/2/87 Response (A.7/2) we specifiedi the expectations in Generic Letter 85-19 which we had no confidence PECo employees could satisfy.

)

We now contend that the burden of proof is'on PECo to show that these expectations l

1 can be met in the light of the PECo employee misconduct,and deficiencies in management which resulted in the current suspension of the Peach Bottom opera-1 ting license. This only reinforces the management and employee lacks which we

]

noted in our brief for appeal,7/2/85, p.3,(ALAB-828):

These violations at both plants ( Peach Bottom and Limerick) were rated at Severity Level III.. The two incidents at Peach Bottom involve deficiencies in oversight of radiological activities..,but the report.. concludes that these deficiencies pervade PEco's management and,therefore could be expeeted in a related form we believe at Limerick in relation to contractors and employees, i.e. " inade,quate oversight and control of contractor activities is not limited to the perticular facility management, but aaso involves corporate management".

2.

lodine spikes in the primary coolant can cause a surge in off-site Iodine-c 131 because there have been reported pathways for radioactive steam to penetrate the containment and reach the environment.

Such releases of Iodine could add in to the routine releases to the environment recorded the Limeridc Annual Radiolog-ical Environmental O eration Meports.( See Poport of 5/86; units of PCI/CU, TABLE p

M _C-XIII, 7 weekly samples of (.03 in air samples, and in milk samples 17 mon %hly readings from < 05 to 4.07 PCI/ LITER.)

66 C0 3

The limits on routine releases of radioactive gases from the Limerick 5

stacks have been set too high, thereby providing a base of Iodine, releases,ns chown in the Annual Radiological Reports, which could be added to,by accide'ntal-N releases from Iodine spikes that could reach dangetous levels in the environ-l

- a:$ nent.

The error in set point releases of radioactive gases from Limerick was built into the operation because the calculation of dosages is based on plant hy -

boundaries of 2400 and 2300 feet instead of the actual boundaries o g g railroad and the river where the.public can habitually have access to 900 feet and 1500 feet of the plant's exhaust stacks.(See ALAB-828,our petition 4/30/85,p.l.)

l r

4 A parallel error is built into the Annual Radiological Reports because 5 mile ( See deport 1986, the nearest approaches to the plant are recorded at s

TABLE C-XI, Croup I Limerick Si te, Boundary Loca tions, # 1053,#1151,# 1451,and

1. 3452.)

The readings recorded for these boundary locations do not measure the exposure of members of the public, including myself,since I have walked along the railroad on a number of occasions,.

The gaseous emissions from the plant have to carry only 900 feet to reach the public at that point.

It is apparent, therefore, that the risk to the public from routine releases of Iodine-131 are considerably greater at the boundaries of the plant than la indicated from the readings recorded at the locations 5 miles from the stacks.

This j

means that any surges of radioactive iodine from spikes that escape to the out-cide atmosphere are added to existing levels from routine releases much higher than any recordings at PECo's monitoring locations which set the plant boundaries l

at 2300/2400 feet.

I

5. The distortedly low recordings of Iodine at the plant boundarie, do not measure the threat to the public from the plants releases or the releases added to the atmosphere from other plant and even accidents at a distance such as Chernobyl.(A.7/2,p.l.),and,of course,any iodine spikes which find a path to the atmosphere can bring Iodine-131 to levels to induce cancer,possibly resulting l

in death.

A letter from five doctors in Vienna in the New England Journal of l

Medicine,Vol 316 No.7, 2/12/87, p 409, records that a study of cow 's milk de-livered to three Austrian dairies when the radioactive cloud panned over after the Chernobyl accident of 4/28/86 showed Iodine -131 at levels of 0 to 3550 Bq during the firs t two weeks aftor the event.

Until there is an official figure on the residues in the PECo area.from the 3 Mile Island and Chernobyl accidents no change should be allowed in the Limericklicense to lower the standards for recording and reporting Iodine upikes.

i

6. Exerpts from an article by Jane dimmonds in New Scientist 23 April 1987, (See Attachments 1 and 2.)give some of the results to date from study of fall-out from Chernobyl and strese the dangers of thyroid cancer from Iodine-131.

The author speaks of the ongoing study by the United Nations committee on the Effects of Atomic Radiation (UNSCEAR) and there is mention (p.43) of the dis-in scientic circles "that the gog of radiation considered safe,(the cussion g

limits) are much too high."

a UNSCEAR on the world wide iapact of Chernobyl by the UN consultan t Dr.indre Bouvilli of Environmental Measuremen t Laboratory in New York will not be finished and assessed before the summer of 1988.

No changes to relar the surveillance of Limerick lodine rele ases should be considered before the results of thia UN study are known.

On the basis of the points in the contentions above,I ask the Board to conduct hearings to consider further evidence which we can provide, cc: NRC Docketing, Staff,and PECo Respe,gt fully yours,g l
