SUBJECT:

PIL6 RIM PUBLIC INTEREST ITEMS There have recently been a number of articles in newspapers published in the area around the Pilgrim Station that suggest there is a pattern of in reased cancers in the area, and that Pilgrim effluent releases might be the ca se. I have enclosed a series of question 6 and answers to address these issui s that indicate what the affluent releasts have been from Pilgrim, and the i.inimal impact these releases had on the piblic. i 1

_ Question: ,

From the stanopeint of human health effects, how ignificant were the n le.ses that were made during the period from late 1974 through most of 19757 Answer:

Not very significant. In terms of airborne noble gas effluents, the Iighest 1 releases occurred in 1974, and the second highest in 1977. 546,000 l1 and I 413,000 Ci respectively. The average annual release during the entire operational life of the plant was 104.000 C1 (see table). This result ; in a cumulative dose to the.whole-body less than 40 arem (1972-86), based on actual effluent release reports resuf ts. As noted in the answer to the pi svious questions, this level of exposure will have a negligible effect on iner!asing cancer risk. In addition, releases from Pilgrim have been within the regulatory limits and Technical Specifications.

l Question: '

Did the spent resin release that occurred on June 11, 1982, result ii high radiation levels offsite?

Answer:

No. The res1n beads were not oispersed offsite. While they wert con-taminated. the resin beads remained onsite, and the contamination appeared to remain fixed to the beads as no detectable contamination was measuied in sewers, stonn drains, or direct exposure on TLDs. Also, no intakes of radio-activity occurred by radiation workers involved in the cleanup activities.

Actual measurements to verify that no radioactivity was released offsiti were j perfonned independently by both the Itcensee and the NRC.  ;

A Pilgrim Off-s ne Re. eases Orcretion of tne PNP 5 facility is governed by operating licensee let hnical Specifications that are based on the dose-design objectives of Apper. dix 1 to 10 CFR 50. Because these design-cbjective values were chosen to permit flexibility of operation while still ensuring that plant operations re uit in -

offsite deses that are as icw as is reasonably achievable (ALARA), the actual radiological impact of plant operation may result in doses close to ci occa-siona11y greater than the dose-design objectives. Even if this si uation exists, the individua' doses for the member of the public subject to noximum exposure will still be very small when compared to natural backgrcund i oses (

100 mrerrs/ year) or the dose limits (500 mrems/ year - total body) speci 'ied in 10 CFR 20 as consistent with considerations of the health ano safety of the public. As a result, the radiological impact on members of the pub 1 e from routine operation of the facility is negligible.

Operating standards of 40 CFR 190 the Environmental Protection A iency's Environmental Radiation Protection Standards for Nuclear Power Operitions, specify that the anniJa1 dose equivalent must not exceed 25 mrems to th; whole body. 75 mrems to the tnyroid, and 25 mrems to any other organ of any member of the public as the result of exposures to materials (radon and its daughters excepted)toplanned discharges the general of radioactive environment from all uranium-fuel-cycle operations and radiation from these operations titat can be expected to affect a given individual. The PNPS facility has operated within these standards.

i Issue: What are the regulatory requirements regarding the operation (or re-start) of nuclear power plants with identified deficiencies in offsite emergency preparedness? ,

Response: The Commission's regulations require the submission and implementation  ;

~

of licensee, statt *nd local governmental emergency plans which meet the standards in 10 CFR 950.47(b) and Appendix E .o 10 CFR Part 50.

As described in the Memorandum of Understanding between FEMA and NRC (50 Fed. Reg.15485, April 18,1985), FEMA has lead responsibility for assessing offsite radiological emergency response plans and prepared-ness. The NRC assesses onsite emergency planning and reviews FEMA's assessment of offsite plans for the purpose of making findings on the overall state of emergency preparedness. The NRC must find reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency.

The Commission recognizes that there can be deficiencies in the emer-gency planning and preparedness associated with a nuclear facility.

However, there must be substantial coepliance with the regulations, i.e., compliance sufficient to find that there is reasonable assurance that adequate protective measures can and will be taken in a radiolo-gical emergency. Indeed, even in those instances where the Comission can no longer make its reasonable assurance finding, emergency pre-paredness deficiencies may not require facility shutdown. See 10 CFR 550.54(s)(2)(fi). In practice, radiological emergency response plans are rarely if ever perfect and complete. This is the reason for the continuing FEMA and NRC oversight of this area. Deficiencies will be found and assessed for significance. While all deficiencies are ex-pected to be corrected, not all will change a finding of reasonable assurance by the NRC.

For an operating plant, such as Pilgrim, the regulations provide con-siderable enforcement flexibility to the NRC. Unlike safety deficien-cies, identification of an emergency planning deficiency does not require immediate shutdown of a facility. Where a significant deficiency in emergency planning is revealed, a 120-day period is initiated in which the deficiency must beiddressed. Even after this i

"120-day clock" has run, the regulations provide that the NRC has the 1 enforcement discretion to allow the plant to continue operation even in the face of such a deficiency. This regulation and the broad flexibility which it accords to the NRC has been judicially approved. )

(County of Rockland v, NRC) _

l 1he Comission's emergency planning rules require " reasonable assu-rance" of " adequate protective measures." 10CFR550.47(a). This requirement recognizes that there cannot be the same degree of pre-cision in emergency planning as is demanded by the NRC for plant design and construction. Commission regulations provide that if the Commission finds that an emergency planning deficiency exists, the facility operator has 120 days to correct the deficiency before the Commission need determine "whether the reactor should be shut down until such deficiencies are remedied or whether other enforcement action is appropriate."

Whereas significant deficiencies in a safety system at an operating reactor would cause it to be shut down at once, the identification of significant deficiencies in emergency planning results in the initia-tion of a four-month period within which the deficiencies are addressed, not in an automatic shutdown of the facility.

Prior to contemplating enforcement action the NRC normally would, consistent with its regulations, provide the licensee a four-month opportunity to demonstrate that the deficiencies are not significant for the plant in question, that adequate interim compensatory measures have been or will be taken, or that there are other compelling reasons for allowing operation to continue.

The United States Court of Appeals for the Second Circuit in County of Rockland v. NRC, held that a nuclear power plant emergency planning deficiency does not require the NRC to take enforcement action to shut down that plant. The Court in County of Rockland specifically recog-nized the four-month grace period set forth in the NRC's emergency planning regulations and further noted that even at the end of that period the NRC still retained the authority to decline to take any

m ..w m w. w u u u, m , -, w a w.r.mm c.a. - - m w.1 < . ww cx - - n a...

3-enforcement action. The County of Rockland court found "nothing in

- the language or legislative history of the [ Atomic Energy Act] or

[ Energy Reorganization Act], nor in the regulations promulgated by the Comission," that required NRC enforcement action even in the event an emergency planning deficiency wert found by the agency.

j Thus, even assuming that the NRC is wrong in its conclusion that there l is no deficiency in the emergency plans sufficient to prevent a finding or reasonable assurance of adequate protective measures, NRC regula-tions provide an additional four months for study of the problem at Davis-Besse before the agency must confront the need to take enforce-ment action.

[The following material is from the final rule on emergency plac.cf rg issued on 12/3/87].

In 10 CFR 550.54(s)(2)(111), the Comission provided that if it " finds that the state of emergency preparedness does not provide reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency...and if the deficiencies...are not corrected within four months of that finding, the Comission will I determine whether the reactor shall be shut down until-such deficien-cies are remedied or whether other enforcement action is appropriate."

In other words, a plant ordinarily may operate for at least four months with deficiencies in emergency planning before the NRC is re-At quired even to decide whether remedial action should be taken.

the time that the Comission created the so-called "120-day clock" for deficiencies in emergency planning, it was settled Comission law (and remains so today) that the NRC must issue an order directing a licen-see to show cause why its license should not be modified, revoked or suspended whenever it concludes that " substantial health or safety issues ha[ve] been raised" about the activities authorized by the license.

In the context of that standard, the 120-uay clock provision of emer-gency planning deficiencies amounts to a Commission finding that, at i least for the first 120 days, even a major deficiency in emergency planning does not automatically raise a " substantial health or safety ,

issue" with regard to plant operation. By contrast, a major safety l deficiency relating to emergency core cooling system--would warrant immediate shutdown.

In sum, despite language indicating that emergency planning was

" essential," the Comission in 1980 created a regulatory structure in which emergency planning was treated somewhat differently, in terms of the corrective actions to be taken which deficiencies are identified, from the engineered safety features (" hardware") that would be relied on in an emergency qt
