Information Notice No. NO 86-32, SUPPLEMENT 1: REQUEST FOR COLLECTION OF
LICENSEE RADIOACTIVITY
MEASUREMENTS ATTRIBUTED TO
THE CHERNOBYL NUCLEAR
PLANT ACCIDENT
Addressees:
All nuclear power reactor facilities holding an operating license (OL) or a
construction permit (CP)
Purpose:
The purpose of this supplement is to provide an update on the response to
Information Notice 86-32 and to inform the licensees that the reporting of
environmental monitoring data attributable to Chernobyl (within 24 hours) is
no longer needed
Discussion:
Information Notice (IN) 86-32 issued May 2, 1986 requested that reactor
licensees report within 24 hours any environmental data collected at their
facility attributable to the Chernobyl reactor incident To date over 46
licensees have responded by reporting evaluated levels of fission products
around their facility All licensees responding to IN 86-32 reported I-131
in rain water and air samples Measurable levels of Cs-134, Cs-137, Ru-103,
Ba-140, La-140, and Te-132 also were frequently reported in air samples
Many of the I-131 concentrations reported in air, milk, and food product
(leafy vegetables) samples, although low, were above the special reporting
levels listed in Table 312-2 of the standard Radiological Effluent
Technical Specifications (RETS)
Responses to IN 86-32 were entirely on a voluntary basis The NRC
appreciates the cooperation received on this effort The licensees' data
were provided to the Federal Interagency Task Force established to deal with
the Chernobyl accident The Environmental Protection Agency has indicated
that "the environmental radiation data supplied by NRC licensees were
instrumental in understanding particular aspects of the US radiological
situation and in answering concerns of US citizens relative to gaseous
radioiodine in the air"

The 24-hour reporting of environmental data requested in IN 86-32 is no
longer necessary Further environmental monitoring results obtained by the
licensees should be reported in accordance with the applicable technical
specification Note that the 30-day special reporting levels in the standard
RETS (referred to above) apply to activity concentrations that result from
plant operations Therefore, licensees with standard RETS should report
results attributable to Chernobyl in their Annual Radiological Environmental
Operating Report
