             INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 3.   INCORPORATION OF DOCUMENTS BY REFERENCE.

     The following documents have been filed by GTS Duratek, Inc. (the
"Company") with the Securities and Exchange Commission and are incorporated
herein by reference:  (a) Annual Report on Form 10-K for the year ended December
31, 1994 and (b) the description of the Company's common stock contained in its
Registration Statement on Form 8-A, as amended on June 7, 1995 (file number 33-
               ).

     All documents filed by the Company pursuant to Sections 13(a), 13(c), 14 or
15(d) of the Exchange Act subsequent to the date of this Registration Statement
and prior to the filing of a post-effective amendment which indicates that all

unsold shall be deemed to be incorporated by reference into this Registration
Statement and to be a part hereof from the date of filing of such documents.
Any statement contained in a document incorporated or deemed to be incorporated
by reference herein shall be deemed to be modified or superseded for purposes of
this Registration Statement to the extent that a statement contained herein or
in any other subsequently filed document which also is or is deemed to be
incorporated by reference herein modifies or supersedes such statement.  The
documents required to be so modified or superseded shall not be deemed, except
as so modified or superseded, to constitute a part of this Registration
Statement.

ITEM 4.   DESCRIPTION OF SECURITIES.  [Not required].

ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Certain legal matters in connection with the issuance of the Common Stock
offered by this Registration Statement are being passed upon for the Company by

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The Company's By-laws provide that the Company shall, to the full extent
permitted by Section 145 of the General Corporation Law of the State of
Delaware, as amended from time to time, indemnify all persons whom it may
indemnify pursuant thereto.  In addition, the Company's Certificate of
Incorporation eliminates personal liability of its directors to the full extent
permitted by Section 102(b)(7) of the General Corporation Law of the State of
Delaware, as amended from time to time.

                                      - 1 -
<PAGE>

        Section 145 of the General Corporation Law of the State of Delaware
permits a corporation to indemnify its directors and officers against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlements
actually and reasonably incurred by them in connection with any action, suit or
proceeding brought by third parties, if such directors or officers acted in good
faith and in a manner they reasonably believed to be in or not opposed to the
best interests of the corporation and, with respect to any criminal action or
proceeding, had no reason to believe their conduct was unlawful.  In a
derivative action, i.e., one by or in the right of the corporation,
indemnification may be made only for expenses actually and reasonably incurred
by directors and officers in connection with the defense or settlement of an
action or suit, and only with respect to a matter as to which they shall have
acted in good faith and in a manner they reasonably believed to be in or not
opposed to the best interest of the corporation, except that no indemnification
shall be made if such person shall have been adjudged liable to the corporation,
unless and only to the extent that the court in which the action or suit was
brought shall determine upon application that the defendant officers or
directors are reasonably entitled to indemnity for such expenses despite such
adjudication of liability.

        Section 102(b)(7) of the General Corporation Law of the State of
Delaware provides that a corporation may eliminate or limit the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the General Corporation Law
of the State of Delaware, or (iv) for any transaction from which the director
derived an improper personal benefit.  No such provision shall eliminate or
limit the liability of a director for any act or omission occurring prior to the
date when such provision becomes effective.

ITEM 9.   UNDERTAKINGS.

A.  Employee Plans on Form S-8.

        The undersigned registrant hereby undertakes:

        (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

             (i) To include any prospectus required by section 10(a)(3) of
Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement;

             (iii) To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.

        (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

B.  Filings Incorporating Subsequent Exchange Act Documents by Reference.

        The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable,


                                      - 3 -

<PAGE>

each filing of an employee benefit plan's annual report pursuant to section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

C.  Indemnification.

        Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                           SIGNATURES

        Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Columbia, and the State of Maryland on this 7th day
of June, 1995.

proceeding, had no reason to believe their conduct was unlawful.  In a
derivative action, i.e., one by or in the right of the corporation,
indemnification may be made only for expenses actually and reasonably incurred
by directors and officers in connection with the defense or settlement of an
action or suit, and only with respect to a matter as to which they shall have
acted in good faith and in a manner they reasonably believed to be in or not
opposed to the best interest of the corporation, except that no indemnification
shall be made if such person shall have been adjudged liable to the corporation,
unless and only to the extent that the court in which the action or suit was
brought shall determine upon application that the defendant officers or
directors are reasonably entitled to indemnity for such expenses despite such
adjudication of liability.

        Section 102(b)(7) of the General Corporation Law of the State of
Delaware provides that a corporation may eliminate or limit the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the General Corporation Law
of the State of Delaware, or (iv) for any transaction from which the director
derived an improper personal benefit.  No such provision shall eliminate or
limit the liability of a director for any act or omission occurring prior to the
date when such provision becomes effective.

ITEM 9.   UNDERTAKINGS.

A.  Employee Plans on Form S-8.

        The undersigned registrant hereby undertakes:

        (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

             (i) To include any prospectus required by section 10(a)(3) of
Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement;

             (iii) To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.

        (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

B.  Filings Incorporating Subsequent Exchange Act Documents by Reference.

        The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable,

                                      - 3 -
each filing of an employee benefit plan's annual report pursuant to section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

C.  Indemnification.

        Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                           SIGNATURES

        Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Columbia, and the State of Maryland on this 7th day
of June, 1995.
