A bound is obtained which generalizes the Carlitz-Uchiyama result, based on a theorem of Bombieri and Weil about exponential sums. This new used to estimate covering radius long binary Goppa codes. lower also derived minimum distance dual code, similar that for BCH an example use number-theory problem estimation codes, as posed in research 9.9 Mac Williams Sloane, <italic>The Theory Error Correcting Codes</italic>.
Within the framework of EUROfusion Program, Dual Coolant Lithium Lead (DCLL) is one four EU breeder blanket concepts that are being investigated as candidates for DEMO. DCLL uses PbLi main coolant, tritium breeder, carrier, and neutron multiplier. The structures, including first wall, cooled with helium. program proposed next years will consider a version limited to 550 °C in order allow use conventional materials technologies. During year activities, draft design has been proposed....
During the last years CIEMAT has been leading activities in European Program to develop an integral breeding blanket with advanced performances work a realistic DEMO scenario. This is dual coolant lithium lead (DCLL) working at limited temperature order allow use of conventional materials and technologies. The design this was finished, including definition tritium extraction system simulations. Then, determined by selection other two concepts as driver blankets for DEMO, focus put on...
Currently, for the EU DEMO, two Breeding Blankets (BBs) have been selected as potential candidates integration in reactor. They are Water Cooled Lithium Lead and Helium Pebble Bed BB concepts. The variants together with associated ancillary systems drive design of overall plant. Therefore, a holistic investigation issues derived by installation its has performed. related to water activation due 16N 17N isotopes impact on primary heat transfer investigated providing guidelines dedicated...
Research Problem 9.5 of MacWilliams and Sloane's book, The Theory Error Correcting Codes (Amsterdam: North-Holland, 1977), asks for an improvement the minimum distance bound duals BCH codes, defined over F/sub 2/m with m odd. objective present article is to give a solution above problem by (i) obtaining Ax (1964) theorem, which we prove best possible many classes examples; (ii) establishing sharp estimate relevant exponential sums, implies very good bounds; (iii) providing doubly infinite...
Tritium behavior in a DEMO reactor is key design issue because of its self-sufficiency and impact on safety. Considering the difficulty handling tritium, that transport, diffusion permeation phenomena involve large number physical properties parameters, it intended to prepare simulation tool predict behavior. A preliminary model for tritium transport at system level has been developed HCPB (Helium Cooled Pebble Bed) breeder concept (DEMO2014), focusing multi-physics release, diffusion,...
Tritium recovery is one of the major issues a future DEMO reactor, in order to comply with requirements tritium self-sufficiency. Within EUROfusion Programme permeation against vacuum (PAV) technique has been considered as baseline for those blankets which use PbLi breeder. A conceptual design rectangular multi-channel PAV its implementation an experimental loop, under construction at CIEMAT, produced. comparison between vanadium/niobium/tantalum and α-Fe membranes performed terms costs,...
For pt.I, see Proc. AMS, vol.III, p.523-31 (1991). The minimum distance of a Goppa code is found when the length satisfies certain inequality on degree polynomial. In order to do this, conditions are improved theorem E. Bombieri (1966). This improvement used also generalize previous result dual code. approach generalized and results obtained about parameters class subfield subcodes geometric codes; in other words, covering radii estimated, further, number information symbols whenever small...
