Dear Mr. Shea:
This is to request an amendment to export license Application No. ISNM 01293 (now pending) which preildes for the export to the United Kingdom of 30 kilograms of plutonium usd 35 kilograms of uranium enriched to j afd W U-235 for use in joint LMFBR fuel pin experiments. We wish to increase the amount of plutonium to M kilograms and the number of fuel pins from 500 to 550 (the amount of enriched uranium remains the same). The shipment of 'these fuel pins will atar: as soon as possible after the issuance of tha export license. The Department of Energy is negotiating with the U.K. Atomic Energy Authority for a Spea.ific Memorandum o.f Agreement that would provice for cooperation in ISBR fuel pin cladding irradiation experiments. For this purpose, we propose to export to the United Kingdom in September 1979, an additional 60 fuel pins containing a maximum of 3 kilegrams of plutonium, up to 7.5 kilograms of natural uranium and up to 5.0 kilograms of depleted uranium. Accordingly, we request that export license Application No. ISNM J1293 be amended to allow for the export of a total cf ~47 'eilnertas of plutonium, 35 kilograms of uranium esiched to 10; U-435, 7.5 kilograms of natural uranium and 5 kilograms of depleted uranium. We would be glad to answer any questions you may have about this proposed export. Sincerely, s s l .l ,Id D.lBengelslorf Director for Nuclear Affairs International Programs

~ n DRAf": 21 July 1973 SPTIFIC MDCPE0UM CF AGRIDT ? between THE U'CTID SIA" TIS LEPARTMEC OF CGGY and the C ITED KD'GDCM ATOMIC E?ERGY AUTHORITY in the area of FUEL PIN CIADDL% EXPERIECS This Agreement (to be known as the Fuel Pin C %dding Agreement) is : ade between the UNITED STATEG T"EpARIHE C OF ENER3Y (hereinafter referred to as " DOE") and the CCTED CJGDOM ATOMIC DERGY AUTHORITY (hereinaf ter referred to as "UKAEA") hereinaf ter called the " Parties". kr:.n AS The Energy Research and Development Administratica (ERDA) and UKAEA under the liquid Metal Fast Breeder Reactors Agreement of 20 September 1976 (hereinafter referred to as "tbe IFJER Agreement") agreed to continue close and long term I cooperation in the field cf IYJER technology. Pt.rsuant *.o the Department of Energy Organisation Act of 1977 ERDA was abolished and all function's transferred to and vested in DOE. Both DOE and UKAEi have an interest in investi ating the behaviour under S irradiation of =aterials for fuel pin cladding and fuel sub-assembly wrappers (ducts) i. fast breeder reactors. Both ICE and UKAEA have an interest in providing support to I.E9 reactor design by means of experimental and theoretical research and development. Both DOE and UKAEA have an interest in providing close cocperation among designers, research and develop =ent personnel and safety asses:sent personnel. _ ,m na
UKAEA has the means for the irradiation of fuel pins in the Prototype Tast Reacter (PTR) sited at Dcunreay and their subsequent examination, and DCE has the treans for the irradiation of fuel pins in the Tast Flux Test Tacility (TUT) at Richland, Washington and their subs. vent examination. DCE and UKAT.A believe that a joint project for comparative irradiating of fc3 and UKAEA fuel pin cladding in PFR or TET followed by post-irrn:iiation exa:nination and analysis of results will provide significant benefits to both Parties. IT IS AGETED AS JUmVS: ARTIC E 1 - C3J C n*E 1.1 The objective of cooperation under this Specific Memorandum of Agreement (SMA) is to establish and to carry out a joint experi-mental progra=me (hereinafter referred to as the "Progra=me") to investigate the b* haviour under irradiation of materials for fuel pin cladding in fast breeder reactors. 1.2 This cooperation shall be a joint project nder and as envisaged in the LM Agreement.

General Descrietion The Prograrne is intended to cer pare the perforence of UK and US fuel pin cladding under si=ilar irradiation conditions, v1 h particular reference to dimensional changes, distortiens and internal cerrscion effects. As part of this Programme similar materials will be irradiated in both UK and US reactors to provide parallel sets o : results for analysis of the effects of different reactor environments and fuel characteristics. For the comparison the progra=me will be carried out in two partt: Fuel pin cladding experiments in the UK a. US-canufact-eed fuel pins using US fuel and US cladding, and fuel pins fabricated in the UK using UK fuel and US cladding, will be irradiated alongside (in the same sub-ssse blies) standard UK fuel pins in the PTR at Dounreay, Caithness. b. Fuel pin cladding experiments in the Uf A i. UK cladding fabricated in the USA into pins contnining US fuel will be irradiated in the FFTF at Richland, Washington alongside US fuel pins; ii. UK-fabricated pins incorporating UK fuel and UK cladding vill be irradiated separately in FJ"7 as part of a material testing program =e, at a latar date. The materials will be subjected to pre-irradiatien and post-irradiation eva-N-tion and the results of these exa=inations, and all other infor=ation arising from the experiments and any other co=parison of results, will be made available to DCE and UYJJ.A. 2. Fuel Pin Claddine Exterieests in the UK _Sub-asse-bly desien a. 1. The collaborative P"R pin irradiatien experiment will ec=prir two sub-asse=blies, each containing 325 unstepped pins, 0.230 in. CD and PE16 grids (all honeycomb) in a PE16 wrapper 2. Both sub-assemblies will-be irradiated in the Inner Zone cf PFR, the nom N 1 irradiation conditions being: 1. Linear rating 400 to 450 w/cm ii. Coolant inlet temperature 4170C iii. Maximum clad mid-wall temperature 70000 (hotspot) iv. Burn-up 7.TA max and 10% cax. - A.1 -

These pins will contain US canufactured fuel pellets 85% smear density, obtained from FPIF fuel pins. They will be returned to the USA after irradiation and non-destructive examination. 11. Up to 90 pins of UK manufacture, using US cladding and UK fuel pellets of 60% smear density, ie up to 18 ctf (nu:ber determined by fabrication capacity) in each of the five cladding types listed above. iii. 40 pins of UK ma=ufacture with UK P316' cladding of which about 10 vill be specially characterised. iv. Remainder of UK manufacture with M316 cladding of which about 10 vill be specially characterised. b. Pin Desirn The 60 pins manufactured in the USA will confom to the pin 1. drawing and specifications provided by the UFJEA in respect of external dimensions, clad thickness, fuel and.reeder colu=n length and location and fuel enrichment, but may incorporate US designs of end cap and internal support features. 2. pina cade in the UK, using both US and UK cladding will use standard UK end cap and internal component designs. The DCE will provide infor=ation on end plug welding parameters for the US-based materials. 3 The filling gas will contain 680'/o heliu=. The US canufact pins may contain tag capsules, containing Xe/Kr mixtures use for pin failure identification purposes in the USA. 4. The pins will be identified by: i. identify numbers scribed on the end cap A,ording to an agreed specification; and ii. binary inerts, either tubular or strip, inserted in the plena, when possible. c. Prorramme It is anticipated that the sub-assemblis untaining the experi=ent. pins will be loaded in the pFR in October 1979 for irradiation whic: will be ccepleted in 4 to 5 or 6 reactor operating penods of 60 da-each for achievement of 7 5% and IC% burnup respectively. This timescale requires that pin manufacture is complete by March 1979 and that sub-assemblies are available at Dounreay by June 1979 - A.2 - wm ww N-g -=we +ge-# .m.y e- - -.. - a y

The first, which has been agreed in soc:e detr, involves =azdacture in the US of fus'. pins to US designs using US fuel a_J both US and UK cladding material. The second, not yet decided upon, would be si=ilar to the first except that it would include both pins of US manufacture unir4 US fuel and claddir4 and pins of UK canufacture using UK fuel and UK cladding. An additional appendix vill be required if this becomes part of the agreed Progrs==e. The detailed proposals for the first experiment are given below: a. FPfF Cvele Desirn 1.
