APPENDIX 17



AGR BURNABLE POISON CABLE FLEXIBILITY



| |  | Whereas the Parties wish to trial certain methods for introducing further flexibilities to the fuel ordering process, the Parties propose to operate revised arrangements for a trial period
from 1 April 2003.
| |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 1. |  | Subject to both SNL and NE giving two months advance notice to BNFL, the arrangements detailed herein may be terminated with effect from or after 1 April 2004.
| | -- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. |  | Unless and until both NE and SNL give notice of reversal under the provisions of paragraph 1 hereof, the following shall continue in effect from 1 April 2003.
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. |  | When placing a firm order for fuel pursuant to Clause 7 SNL shall provide the combination in terms of number of cables and their gadolinium density for each Fuel Element applicable to that
order.
| | -- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. |  | SNL shall be entitled to amend the said cable combination at any time up to the third Friday of the third Month prior to delivery up to a maximum additional overall cable requirement of 1400
cables applying to all 7 advanced gas-cooled reactor power stations operated by NE and SNL combined, with no limitation on changes from cabled to uncabled or vice versa. SNL shall use all reasonable endeavours to provide the most accurate
information in terms of cabling requirements.
| | -- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. |  | Recognising that SNL in the past has amended its cable requirements at the third week of the third month prior to delivery and that due to unforeseen circumstances stations may need to change
cable requirements after this date, SNL shall also be entitled up to two calendar months prior to delivery to increase or decrease cables, up to a further maximum additional overall cable requirement of 1400 applying to all 7 advanced gas-cooled
reactor power stations operated by SNL and NE combined, with a maximum net change at any time during each delivery period from cabled to uncabled, or vice versa, of four stringers worth of Stage 3 fuel.

APPENDIX 20



CALCULATION OF OUTTURN ELECTRICITY PRICE



Intention



The Parties agree that it is their intention to establish a price index that reflects the baseload wholesale electricity price that the SNL Groups advanced gas-cooled reactor
generation would be exposed to, subject to a specified treatment of any future environmental legislation. This price index (the Outturn Electricity Priceor OEP) will be used to calculate rebates and surcharges on
contractual payments for fuel and receipt of spent fuel and so provide the SNL Group with a partial hedge of the electricity price risk associated with its advanced gas-cooled reactor output.



The price is calculated on the basis of publicly available market price indicators, with a weighting of
75% to contracts sold for a season during the preceding six months, and the remaining 25% to contracts sold on a month-ahead basis. For the Year commencing on 1 April 2003, an annual pricing mechanism shall be used in place of the seasonal
calculation, so as to ensure consistency of value with the non-binding heads of terms as initialled by Mr. John Edwards and Mr. Keith Lough, on behalf of BNFL and British Energy plc respectively, on 28 November 2002.



The Parties will establish a means of calculating, before all of the data are available that are
required to calculate the Outturn Electricity Price for a particular Year, a forecast of the Outturn Electricity Price for that Year (Forecast Outturn Electricity Price).



In this Appendix 20, the AGR Power Stations shall mean SNLs AGR power stations and the NE AGR Power Stations shall
mean NEs advanced gas cooled reactor power stations.

Definitions



Actual Level of AGR Generation
 defined in section 3.



Additional AGR Environmental
Value  for any Year, the additional effective price achievable by baseload advanced gas-cooled reactor generation beyond that captured in Initial Outturn Electricity Price, that arises directly from Environmental Legislation. The
calculation of such achievable price shall take into account the potential to access the most favourable price across different market segments (including for the avoidance of doubt sales directly to consumers), net of the incremental costs of
accessing such market segments to achieve such prices or any other costs imposed on nuclear generation associated with such Environmental Legislation. For the avoidance of doubt, the Additional AGR Environmental Value may only be a positive number
or zero.



Agreed Price Reporter  A Price Reporter whose prices the
Parties have agreed or the Expert has determined should be included in making the calculations required in this contract.

for baseload electricity for a particular Pricing Month. In the event that no such trades are reported by any Agreed Price Reporter for that Trading Day, the arithmetic mean of the bid and offer prices quoted on that day across all Agreed Price
Reporters for the relevant Pricing Month shall be used in place of the mean of the prices of contracts traded.



Daily Price for the Season  for any Trading Day, the volume-weighted mean across all Agreed Price Reporters of the prices of contracts traded on that Trading Day for baseload electricity for a particular
Pricing Season. In the event that no such trades are reported by any Agreed Price Reporter for that Trading Day, the arithmetic mean of the bid and offer prices quoted on that day across all Agreed Price Reporters for the relevant Pricing Season
shall be used in place of the mean of the prices of contracts traded.



Environmental Legislation  any carbon tax, exemption of nuclear generation from the Climate Change Levy, or any other climate change related measure put in place by the Government of the United Kingdom subsequent to 29
November 2002 which affects the value of nuclear generation (but for the avoidance of doubt excluding any changes in rates payable by NE or SNL).



Fuel Contract Equivalent Electricity Volume shall be 5 TWh.



Initial Outturn Electricity Price  (a) for the Year ending 31 March 2004, the sum of 0.75 times the Average Price for the Year and

BNFL/BEG(UK) COMMERCIAL IN CONFIDENCE



QMi j+= BMU Metered Volume for exporting BMU i in Settlement Period j



QMi j-= BMU Metered Volume for importing BMU i in Settlement Period j



a= the percentage share from time to time determined of the total net system losses attributable to the BM Units
that belong to delivering trading units (as those terms are used in paragraph T2 of the Balancing and Settlement Code) for Settlement Period j, which as at the date hereof is 45%.



Vj k= GNN Station output of Reactors
in the AGR Power Stations k in Settlement Period j.



GNN Station output represents the
electricity sent to the grid net of what is used on the power station site.



Actual
Level of AGR Generation =Actual Level of NE AGR Generation in England and Wales + Actual Level of SNL AGR Generation in Scotland.



Where appropriate, the terms above shall be used in the sense in which they are used in the Balancing and Settlement Code.



In the event that the allocation of transmission losses is varied, or BETTA is introduced, or the
ownership of any of the AGR Power Stations or the NE AGR Power Stations changes, or any of the terms above ceases to be available to either or both of the Parties, then the Parties shall agree such changes to the above calculation to give effect to
the principle outlined in the definition of Actual Level of AGR Generation. In the event that the Parties are unable to reach agreement on such changes, then the matter shall be referred to an Expert for determination.



In the event that some or all of the items of data required to calculate the Actual Level of AGR
Generation is not available to BNFL, SNL shall provide BNFL with such items of data that BNFL reasonably requires within 5 Trading Days of BNFL requesting said items of data.



PROTOCOL



Agreed Price Reporters



The Parties shall from time to time agree who shall represent the Agreed Price Reporters. Initially the Agreed Price Reporters shall be:



| |  | Argus European Energy Report
|- |  | ----------------------------



| |  | The Heren Report  European Daily Electricity Markets
|- |  | -----------------------------------------------------



There shall always be at least one and not more than five Agreed Price Reporters. If the Parties are unable to agree on the Price Reporters then the matter will be referred to an
Expert who will be required to determine which Price Reporters shall be the Agreed Price Reporters. The Parties may agree to exclude or adjust a price quoted from one or more Agreed Price Reporters. Any corrections issued by the Agreed Price
Reporters after the initial publication of their reports shall be taken into account in these calculations. The Parties may agree to exclude or adjust such corrections.



In the event that the relevant reported market prices become unavailable from any Agreed Price Reporter on either a temporary or permanent basis, or
that such prices have ceased to be appropriate for use (e.g. due to illiquidity underlying such index) such that the Outturn Electricity Price calculated by this methodology has ceased to provide a fair reflection of the baseload wholesale
electricity prices that the SNL Groups advanced gas-cooled reactor

BNFL/BEG(UK) COMMERCIAL IN CONFIDENCE



generation would be exposed to (subject to the specified treatment of any future environmental legislation), the Parties shall agree a suitable alternative, and/or an
adjustment to the overall mechanism for the establishment of the Initial Outturn Electricity Price, such that the commercial basis of the agreement is not altered.



In the event of any market developments or other changes, the effect of which is to render any part of the calculation of Outturn Electricity Price
unworkable or inappropriate, the Parties will negotiate in good faith to reach an agreement on such changes as are required to preserve the original economic intent. In the event that the Parties are unable to reach agreement on such changes, then
the matter shall be referred to an Expert for determination.



Environmental
Legislation



In the event that the Parties are unable to reach agreement on the
existence of any Environmental Legislation or the treatment of any of the calculations associated with such Environmental Legislation then the matter shall be referred to an Expert for determination. The scope of any Expert determination shall
include all aspects of the process of deriving Outturn Electricity Price from Initial Outturn Electricity Price except where both Parties explicitly waive this condition.



Provision of Estimates



SNL shall make good faith estimates of the Forecast Environmental Adjustment as required to meet the timescales of invoicing. In the absence of such an estimate for any particular
invoice, the last estimate provided or determined for that Year shall be used, where the initial estimates of Forecast Environmental Adjustment for each Year in the contract are deemed to be zero. In the event of any dispute by BNFL of the level of,
or requirement for, such an estimate that is not resolved within 10 Trading Days of the dispute being raised, either Party may refer the matter to an Expert for determination.



SNL shall make good faith estimates of the Forecast AGR Generation in Year as required to meet the timescales of invoicing. In the event of any
dispute by BNFL of the level of such an estimate that is not resolved within 10 Trading Days of the dispute being raised, either Party may refer the matter to an Expert for determination.



Expert Determination



If any matter is referred to an independent expert (the Expert) in accordance with this Appendix, the Expert shall be appointed by agreement between the Parties. If
the Parties fail to agree upon that appointment within 10 Trading Days of a Party notifying the other Party of its decision to refer the matter to an Expert, the President of the Law Society of England and Wales may appoint the Expert on the
application of either Party.



The Expert shall have power to make amendments to this
Agreement binding on the Parties consistent with any relevant requirements, purposes or restrictions concerning those amendments expressly provided for in this Agreement. The Parties agree that it is their intention that in the absence of their
ability to agree any required amendments to this Agreement, this Agreement should continue and not come to an end or be deemed to be void or voidable in accordance with the doctrine of frustration or any other legal theory. Accordingly, if the
Expert is unable to decide upon any amendments based on the express or implied intentions of the Parties, the Expert shall be entitled to have regard to the way in which similar issues or amendments are addressed or are proposed to be addressed by
other electricity industry participants and to substitute the Experts own view of what is reasonable in all the circumstances.



25

BNFL/BEG(UK) COMMERCIAL IN CONFIDENCE



The Expert shall act as an expert and not as an arbitrator and shall give his or her determination in writing. In the absence
of fraud or manifest error, the determination of the Expert shall be final, conclusive and binding upon the Parties.



The Expert shall determine the procedure to be followed by the Expert for the purpose of making a determination provided that the Parties shall use their respective reasonable
endeavours to ensure that he or she makes his or her determination within 20 Trading Days of being appointed. Each of the Parties shall bear one half of the costs of the Expert unless the Expert determines otherwise. Pending the determination of any
amendments to this Agreement by the Parties or the Expert, the Parties shall continue to the extent possible to perform their obligations under this Agreement.



Audit



In the event that BNFL is wholly reliant on information provided by SNL to enable BNFL to calculate or check SNLs calculations of any of the factors required to calculate the Outturn Electricity Price, the Forecast
Outturn Electricity Price, or the Actual Level of AGR Generation, SNL shall at all times upon reasonable notice allow BNFLs auditors, its officers, agents and other persons authorised by BNFL in writing (or, at SNLs request, an
independent auditor agreed between the Parties or appointed by the Expert in the event that the Parties cannot agree) to have access to inspect the basis on which SNL has provided such information. SNL shall keep such books and records as BNFL may
reasonably require for the purpose of verifying said information. The records detailed in this clause shall be retained by SNL and made readily available upon reasonable notice for inspection by BNFL, its officers appointed agents or independent
auditor as applicable for a minimum period of 2 Years from the date of the record.
