SteriGenics International, Somerset, NJ: Exemption From 10 CFR
36.23(a); Environmental Assessment, Finding of No Significant Impact,
and Notice of Opportunity for a Hearing

AGENCY: Nuclear Regulatory Commission.

ACTION: SteriGenics International, Somerset, NJ: Exemption from 10 CFR
36.23(a); Environmental Assessment, Finding of No Significant Impact,
and Notice of Opportunity for a Hearing.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is considering
authorizing SteriGenics International, Inc. (SteriGenics or the
licensee) an exemption to use a cell door which prevents an individual
in the radiation room from leaving.

SUPPLEMENTARY INFORMATION:

Proposed Action

    SteriGenics is licensed by the NRC to irradiate materials, except
explosives, flammables, and corrosives using cobalt-60 in a panoramic
wet-source-storage irradiator. The licensee requested, in a letter
dated September 26, 2000, that the NRC grant an exemption from 10 CFR
36.23(a) to use a cell door which prevents an individual in the
radiation room from leaving. SteriGenics has been conducting
irradiations using this cell door since the license was issued on
February 1, 1999. The NRC staff has determined during an inspection of
the facility, that the cell door does not meet 10 CFR 36.23(a) which
requires that doors and barriers not prevent an individual in the
radiation room from leaving.

Need for the Proposed Action

    Part 36 irradiators use high activity sealed sources of radioactive
material in a facility constructed so that the sealed sources and
material being irradiated are contained in a shielded volume (radiation
room). In many units, sources are stored under water (wet-source-
storage). Irradiator facilities typically incorporate the use of a
shielded ``maze'' which allows an individual to move to a shielded area
within the radiation room and a door to the radiation room which allows
an individual to exit the radiation room at any time.
    The exemption is needed so that SteriGenics can carry out its
business of irradiating materials in this irradiator. The door to the
radiation room of this irradiator serves as an integral part of the
shielding and must be closed prior to exposing the radioactive sources
to conduct an irradiation. The design of the irradiator control system
does not allow the radioactive sources to be raised unless the door is
closed. Once closed, an individual located in the radiation room cannot
open the door and, therefore, is unable to leave the radiation room as
required by 10 CFR 36.23(a). An individual in the radiation room with
the door closed can prevent the sources from rising by pulling a cord
on the room wall and thereby prevent radiation exposure.
    SteriGenics has proposed modifications which provide a level of
safety equivalent to that which is provided by compliance with 10 CFR
36.23(a). Currently, there are two pull cords inside the radiation
room. One runs the length of two of the room walls, the second the
length of the third. The fourth wall is covered by equipment. The
presence of equipment in the radiation room forces individuals in the
radiation room to be near one of these cords. Both of these cords must
be actuated as part of the irradiator startup sequence. This actuation
assures that the cords are functional and that the operator has
searched the cell prior to beginning an irradiation. Once the startup
sequence has been completed, the pull cords change function and pulling
either cord will prevent the sources from rising or cause them to
return to the shielded position if they have begun to rise. SteriGenics
proposes to modify the irradiator control circuit logic so that if an
individual pulls one of these cords twice, in addition to the sources
returning to the shielded position, the cell door will open after a
short delay. The control system logic will assure that the door does
not open until and unless the sources are in the fully ``down''
position and radiation levels in the room are normal. The delay is
caused by the operation of this logic and the fact that it takes
between 15 and 30 seconds for the door to open.
    SteriGenics will also relocate the ``set-up'' key switch to the far
corner inside the radiation room. Currently, this switch is located
outside the cell door. Inserting the key and turning this switch begins
the sequence which eventually allows moving the sources. Within 90
seconds of turning the switch, the operator must search the radiation
room, pull each cord once, exit the room and close the shield door. The
operator must then place the key in the control console and may then
move the sources. Placing the switch in the room forces the operator to
bring the key which is used to move the sources (as required by 10 CFR
36.31(a)) into the radiation room during the ``set-up'' process. This
increases the assurance that this requirement will be met by
substituting an active control for the current administrative control
(the operator is required by existing procedure to take the key into
the room). Taking the key into the room during ``setup'' assures that
no one other than that operator can move the sources.

Environmental Impacts of the Proposed Action

    No radioactive material is released into the environment, all of
the radioactive material is wholly contained within the shielded
irradiator and there will be no changes to radiation dose rates outside
the irradiator. The radiation dose rate outside this irradiator meets
regulatory requirements and is similar to the dose rate outside
traditional panoramic wet-source-storage irradiators which meet the
requirement in 36.23(a). Therefore, the modification will not result in
any significant environmental impacts.

Alternatives to the Final Action

    As required by Section 102(2)(E) of NEPA (42 U.S.C. 4322(2)(E)),
the staff has considered alternatives to the final action including
denying the exemption or requiring that SteriGenics comply with 10 CFR
36.23(a). These options were not adopted because they would provide no
gain in protection of the human environment and they would be
significantly detrimental to SteriGenics. Denying the exemption request
would result in SteriGenics ceasing all irradiations and either
redesigning and substantially modifying the physical facility or
disposing of the radioactive sources and decommissioning the facility.
In order for SteriGenics to comply with 10 CFR 36.23(a) they need to
extensively modify the existing irradiator to incorporate a shield
maze. This would be expensive and would prevent the use of the existing
conveyor system, requiring additional expenditures for modifications.

Alternative Use of Resources

    Alternative use of resources was considered as stated above.

Agencies and Persons Consulted

    Agencies or persons outside the U.S. Nuclear Regulatory Commission
were not consulted because there will be no significant impact on the
environment from the proposed activity.

Identification of Sources Used

    Letters from SteriGenics to the U.S. Nuclear Regulatory Commission,
Region I, dated:

[[Page 3621]]

1. January 5, 2000 (ML003676755)
2. February 4, 2000 (ML003684178)
3. September 26, 2000 (ML003754079)

Finding of No Significant Impact

    Based on the above EA, the Commission has concluded that
environmental impacts that would be created by the proposed action
would not have a significant effect on the quality of the human
environment and a Finding of No Significant Impact is appropriate.
Accordingly, the preparation of an Environmental Impact Statement is
not warranted.

Documents

    Documents submitted by SteriGenics are available for public
inspection from the Publicly Available Records (PARS) component of the
NRC's document system (ADAMS). ADAMS is accessible from the NRC Web
site at http://www.nrc.gov/NRC/ADAMS/index.html (the Public Electronic
Reading Room). Assistance with the Public Electronic Reading Room may
be obtained by calling (800) 397-4209. The accession numbers for the
licensee's documents referred to in this Assessment are listed next to
the document date above.

Opportunity for a Hearing

    Any person whose interest may be affected by the issuance of this
action may file a request for a hearing. Any request for hearing must

that is the subject matter of the proceeding; and
    4. The circumstances establishing that the request for hearing is
timely--that is, filed within 30 days of the date of this notice.
    In addressing how the requestor's interest may be affected by the
proceeding, the request should describe the nature of the requestor's
right under the Atomic Energy Act of 1954, as amended, to be made a
party to the proceeding; the nature and extent of the requestor's
