Exhibit        Description

No. 1          RNS Announcement, re:  Update on AmerGen Disposal dated
               5 December 2003


5 DECEMBER 2003

BRITISH ENERGY PLC ("British Energy" or the "Company")

POSTING OF AMERGEN CIRCULAR AND POTENTIAL DELISTING


Further to British  Energy's  announcement on 10 October 2003 in relation to the
proposed disposal of its interest in AmerGen Energy Company,  LLC ("AmerGen") to
Exelon  Generation  Company,  LLC  ("Exelon")  (the  "Disposal"),   the  Company
announces that it has today posted a circular to its  shareholders  convening an
extraordinary  general meeting to seek approval for the Disposal,  which will be
held on 22  December  2003 at the  Sheraton  Grand  Hotel,  1  Festival  Square,
Edinburgh EH3 9SR commencing at 11.00am.

Disposal

At closing,  British Energy expects to receive approximately US$277 million from
Exelon in cash subject,  amongst other things,  to any post-closing  adjustments
relating to working capital levels,  unspent  nuclear fuel,  inventory,  capital
expenditures and low-level waste disposal costs at the time of closing.

Potential delisting

In view of the size of the  Disposal in relation to the British  Energy group of
companies  (the  "Group"),  shareholder  approval  will be  required  whilst the
Company  maintains a listing for its ordinary shares on the Official List of the
UKLA.

The Company is endeavouring  to satisfy the other  conditions to the Disposal as
soon as  possible.  Closing is  expected  to occur  sometime  between the end of
December 2003 and 31 March 2004.

The  proposed  Disposal is a key element of the  proposed  restructuring  of the
Group  which was agreed  with  certain  of the  Group's  creditors  and with the
Secretary  of State for Trade and Industry  ("Secretary  of State") on 1 October
2003  (the  "Proposed  Restructuring").  The  Proposed  Restructuring  involves,
amongst  other  things,  the  compromise of certain of the Group's debts and the
assumption by the Nuclear Generation Decommissioning Fund Limited, to be renamed
the Nuclear  Liabilities  Fund  Limited  ("NLF") and the  Secretary  of State of
financial   responsibility   for  funding   certain   nuclear   liabilities  and
decommissioning costs.

The  importance  of the  Disposal  to the Group in the  context of the  Proposed
Restructuring is such that if ordinary shareholders do not vote in favour of the
Disposal,  then in  order  to try and  secure  the  financial  stability  of the
Company,  the board of the Company (the "Board") has decided that it will delist
the Company's shares from the Official List of the UKLA and cease trading on the
London  Stock  Exchange in order to proceed  with the  Disposal  (subject to the
other  conditions)  without the approval of  shareholders  (which upon delisting
will cease to be required).

This decision has been taken  reluctantly  by the Board and reflects the Board's
belief that the Disposal is a critical part of a successful restructuring of the
Group.  The Board has taken this step  because it believes  that in light of the
short term pressures on liquidity which the Company is currently  facing,  it is
in the interests of the Company to expedite the closing of the Disposal in order
to access the sale  proceeds as soon as possible.  The Board also believes it is
necessary to minimise  the period  during which the Group is exposed to the risk
of  further  unplanned  outages  or other  events  which  may add to short  term
liquidity pressures, pending receipt of the Disposal proceeds.

Accordingly,  should shareholders not vote in favour of the Disposal,  it is the
Board's  intention  to cancel the  listing of its  ordinary  shares and A shares
(together,  the "British  Energy Shares") on the Official List of the UKLA, as a
result of which the British  Energy Shares will cease to be traded on the London
Stock  Exchange.  In this event, it is expected that delisting would take effect
at 8.00am on 7 January  2004 and the last day for  dealings  in  British  Energy
Shares would be 6 January 2004.

In accordance  with the articles of association of the Company,  the Company's A
shares will not carry any rights to attend or vote at the extraordinary  general
meeting on 22 December 2003.  Holders of A shares  (whether or not they also own
ordinary shares) in the capital of the Company have nonetheless been sent a copy
of the circular concerning the Disposal in order to notify them of the Company's
intention to delist the British Energy Shares from the Official List of the UKLA
and to cease  trading  on the  London  Stock  Exchange  if the  Disposal  is not
approved by the holders of ordinary shares.

Use of proceeds of Disposal and liquidity

As  previously  announced,  the Company has recently  agreed,  subject to formal
documentation,  a temporary  increase in the amount of the facility  extended to
the Company by the Secretary of State (the  "Government  Facility")  from GBP200
million to GBP275  million.  The temporary  increase in the Government  Facility
will only be  available  until the  earlier  of  receipt  by the  Company of the
proceeds of the Disposal and 22 February 2004.

The  proceeds of the  Disposal,  net of  transaction  costs and break fees,  are
expected in the first  instance to be used to repay  outstanding  sums under the
Government  Facility  and any  remainder  will be retained  for working  capital
purposes and for funding the Group's collateral requirements. The receipt of the
Disposal  proceeds will therefore  significantly  increase the Group's financial
flexibility.

The Board is exploring  initiatives to reduce the demand for trading  collateral
and  to  achieve   sufficient   liquid   resources  to  implement  the  Proposed
Restructuring,   including   investigating   the  availability  of  third  party
financing.  However,  the  Proposed  Restructuring  and  therefore,  the working
capital available to the Group, remains subject to a large number of significant
uncertainties  and  important  conditions  (which were outlined in the Company's
announcement on 1 October 2003).
