M. CLARKE</p><p>A review of Heavy Water and the Wartime Race for Nuclear</p><p>Energy. By P. F. DAHL. (Institute of Physics Publishing ,</p><p>1999.) Pp. xvi+ 400. 35.00, $60.00 (hbk). ISBN 0 7503</p><p>0633 5. Scope: historical survey. Level: non-specialist .</p><p>At the end of every century, and especially at the end of the</p><p>millennium, the historians sharpen their pencils (or word</p><p>processors) in order to set the previous hundred years in a</p><p>context appropriate to their personal view of the develop-</p><p>ment of their country, continent or world over those years.</p><p>In many cases, there are de ning historical incidents or</p><p>inventions which can characterize a century, or at least</p><p>some part of it. For my life, which spans just more than the</p><p>last 50 years of the century, the two most signi cant</p><p>in uences were nuclear weapons and computers. This is of</p><p>course, a western, northern hemisphere viewpoint which</p><p>may be unrecognizable to someone who grew up during the</p><p>1960s in say, southern Africa or parts of Oceania. Those,</p><p>like me, who lived through the Cuban missile crisis, will</p><p>remember the almost palpable sense that we were on the</p><p>edge of oblivion; and then the subsequent relief that nuclear</p><p>weapons somehow held the fragile peace for more than 40</p><p>years, until the communication revolution, red by</p><p>advances in computer technology, broke down many of</p><p>the barriers between nations. (A former colleague insisted</p><p>that the cold war could have been ended by dropping free</p><p>computers into those countries behind the Iron Curtain .) I</p><p>am sure that many others share a similar view of these</p><p>in uences on their lives, so that the social history of the</p><p>western world can be seen to have been shaped and driven</p><p>by certain advances in science and technology. So, I became</p><p>a nuclear physicist, and nd myself reviewing Per Dahl s</p><p>book.</p><p>In Dahl s introduction he oers that his book is `not a</p><p>book about science, but a social history of science and he</p><p>encapsulates through his story of heavy water, the</p><p>discoveries leading to nuclear power and ssion bombs,</p><p>in which this elusive substance played a role, believed to be</p><p>of critical importance at the time, but which was to prove</p><p>inconsequentia l in the long term future of nuclear weapons</p><p>and for nuclear power (with the exception of the CANDU</p><p>reactors in Canada). The social and political fallout which</p><p>accompanied these discoveries for the remainder of the</p><p>century are outside the scope of this book (and my review),</p><p>but are well documented elesewhere.</p><p>Dahl begins his story, appropriately , at Oslos Fornebu</p><p>airport in March 1940 where, with the help of Frank Foley</p><p>of MI6, two scientists managed to smuggle out thirteen</p><p>canisters of heavy water from under the noses of German</p><p>agents, just before the fall of Norway. The two physicists</p><p>were the Austrian, Hans Von Halban and a wandering</p><p>Russian, Lew Kowarski, both co-workers with Frederic</p><p>Joliot-Curie in Paris. The adventures of the canisters and of</p><p>Halban and Kowarski (and Foley), seem to form a singular</p><p>thread through the amazing story that Dahl unfolds; it is a</p><p>story of intrigue, espionage and adventure which many</p><p>writers of spy novels could not outdo. This thread, a small</p><p>part of the story, deserves a more popular presentation</p><p>than Dahl can really present in this book, but without the</p><p>services of Hollywood, or perhaps of a playwright like</p><p>Michael Frayn (Copenghagen), it is unlikely to see the light</p><p>of day entitled as, say, Broompark the name of the</p><p>Scottish coal steamship which nally sneaked out of</p><p>Bordeaux, evading the German U-boats, to deliver 26</p><p>canisters of heavy water, eventually, to Windsor Castle by</p><p>way of Wormwood Scrubs prison. Back in Paris, Joliot-</p><p>Curie managed to convince the occupying German</p><p>authorities that the Broompark had been sunk.</p><p>In the rst few chapters, Dahl introduces us, in a fairly</p><p>gentle way, to the background history of the early work on</p><p>radioactivity, with research activities dominated by scien-</p><p>tists in England, France and Germany. The identity of the</p><p>mysterious radiation that was the neutron was missed,</p><p>narrowly, by Bothe in Berlin and Joliot-Curie in Paris, but</p><p> nally veri ed by Chadwick in Cambridge, and triggered</p><p>research projects all over Europe. For Frederic and Irene</p><p>Joliot-Curie, this must have been a galling disappointment ,Dr N. M.

We also meet `a comedy of errors which led to</p><p>the discovery of the heavy isotope of hydrogen, eventually</p><p>called `deuterium by Urey who also settled on `deuteron</p><p>for the nucleus, overturning, thankfully , the other candi-</p><p>date names of `dygen and `pycnogen ! Here too, we meet a</p><p> gure who dominates the story of heavy water until his</p><p>tragic death from a bullet through the head in the last few</p><p>pages of this book and within a few weeks of the armistice.</p><p>He was Leif Tronstad, a Norwegian electro-chemist who</p><p>became a consultant to Norsk-Hydro. This Norwegian</p><p>company ran the hydroelectric plants which generated</p><p>electricity, made hydrogen by electrolysis, and, under</p><p>Tronstads guidance, were adapted to produce water</p><p>enriched in deuterium. Next, we follow the scientists of</p><p>various countries, seeking the explanation of the observa-</p><p>tion by Hahn and Strassman that the element barium was</p><p>mysteriously produced in reactions of neutrons with</p><p>uranium. This was correctly interpreted by Otto Frisch</p><p>and Lise Meitner as the splitting, or ssion, of the nucleus</p><p>of uranium.</p><p>This is the critical point in the story; the genie of nuclear</p><p> ssion was out of the bottle, and within months the</p><p>concepts of a chain reaction leading to a power-producing</p><p>pile or even to a bomb were well established. The race was</p><p>on, and Per Dahl whirls us though the following intrigue</p><p>connected with heavy water, which was the moderator of</p><p>choice for the experiments in chain reactions. Here we see,</p><p>not only science as social history its demands and</p><p>priorities altering or even driving the decisions of govern-</p><p>ments and the military authorities, but scientists playing</p><p>out their own precarious roles and lives against the</p><p>patchwork of others lives across the face of Europe. In</p><p>particular , Dahl gives us lavish detail about the attempts to</p><p>disrupt and destroy the heavy water production at the</p><p>famous Vemork hydro plant in Rjukan, Norway, and deals</p><p>well with some of the arguments which have arisen since</p><p>those times about the real necessity (or otherwise) of these</p><p>attempts, given that it was known at the time that the</p><p>German eorts in achieving a chain reaction had not</p><p>progressed much further than Joliot had achieved before</p><p>the occupation. Following the disasterous `Freshman raid</p><p>on Vemork, Leif Tronstad led a band of Norwegian</p><p>saboteurs with local knowledge, and eectively destroyed</p><p>the heavy water installation in the Vemork plant. But not</p><p>for long; repairs were carried out, and German demand for</p><p>the heavy water increased as they were forced to ee Berlin</p><p>in the face of mounting air raids. Following the repairs, an</p><p>Allied air raid of 140 ying Fortresses dropped over 700,</p><p>500-pound bombs on the Norsk Hydro plant, (and by</p><p>mistake, another 118 bombs on the nitrate plant at Rjukan)</p><p>with a total loss of 21 lives. This led to a plan to dismantle</p><p>the heavy water plant at Vemork and ship some 600</p><p>kilograms of enriched water in 49 drums to Germany.</p><p>Tronstads group, led by Knut Haukelid (Skis against the</p><p>atom) were able to sabotage this eort on the rst stage of</p><p>its journey by blowing up the ferry Hydro; 18 lives were lost</p><p>as the ship, with three rail cars, and all but four of the</p><p>heavy water drums sank 400m deep into the fjord. These</p><p>losses of life caused great concern amongst the Norwegian</p><p>authorities exiled in England, and has led to much criticism</p><p>of Allied motives and actions since that time. However,</p><p>Dahl points out that the hydroelectric plants were still of</p><p>strategic importance, even without the heavy water plant,</p><p>because one of their principal functions was the production</p><p>of hydrogen, and ammonia for fertiliser which were</p><p>desperately short in Germany, where fuel stocks were</p><p>badly depleted. Later in the book, almost as an aside, he</p><p>mentions also that the ammonia was a major feedstock for</p><p>the explosive industries. These reasons alone do not, of</p><p>course, justify the loss of life, but in the great scheme of the</p><p>world war, they give a lie to the accusations that the raids</p><p>on Vemork were pointless and achieved nothing, and</p><p>perhaps give a little comfort to the families of the brave</p><p>Norwegians who gave so much.</p><p>As a scientist, I appreciated Dahls eorts to give a</p><p>balanced view of the scientists involved in the history of the</p><p>chain reaction. He rightly credits the quality of the French</p><p>eorts under Joliot-Curie, whilst the eorts of the British</p><p>were more modest. He also chronicles the incredible</p><p>struggles of the German team, who suered a uranium</p><p> re, frequent moves to avoid air raids, and constant</p><p>political and military interference; in their nal attempt at a</p><p>chain reacting pile, Heisenberg and his colleagues ended up</p><p>in a cave in Haigerloch in 1945 where they were nally</p><p>tracked down by the advancing Allied forces. The German</p><p>scientists were transferred to England, and the story of their</p><p>debrie ng is told in the transcripts of the Farm Hall</p><p>recordings. Dahl also gives brief details of the scienti c</p><p>eorts in Russia and Japan. The irony of the story is that</p><p>the chain reaction was achieved, long before most incidents</p><p>in this book, by the diaspora of European scientists in the</p><p>United States who, under Fermi s leadership, achieved the</p><p> rst chain reaction with a graphite pile in 1942. For</p><p>28minutes it had an output of one-half of a watt; this was</p><p>the feeble beginning of chain reactions in nuclear ssion,</p><p>which eventually became the greatest power in the world, in</p><p>more senses than one. The rest, as they say, is history, and</p><p>as Michael Faraday said of electricity `One day, Mr</p><p>Gladstone, you will tax it ; and, of course, they did!</p><p>I enjoyed Per Dahl s book immensely; it has some</p><p>passages which may prove tough going for non-specialists ,</p><p>but its structure, with references to detailed notes in the</p><p>appendices, leaves the reader with a clear path through the</p><p>story, but with plenty of detail in the notes should one wish</p><p>to browse. Moreover, it moves at a good pace, and</p><p>addresses many aspects of the story of heavy water that</p><p>Essay review126</p><p>Dow</p><p>nloa</p><p>ded </p><p>by [</p><p>Um</p><p>e U</p><p>nive</p><p>rsity</p><p> Lib</p><p>rary</p><p>] at</p><p> 04:</p><p>16 2</p><p>2 N</p><p>ovem</p><p>ber </p><p>2014</p></li><li><p>have been somewhat neglected. I marvelled at its detail, but</p><p>was made somewhat conscious of my age to nd in these</p><p>pages the names of people I had met, or worked with, or</p><p>had formerly occupied my o ce (Mark Oliphant, Helene</p><p>Joliot and Alan Nunn-May respectively). So, do we need</p><p>more science as social history? We do indeed, and plenty of</p><p>it, to educate and certainly to entertain the younger</p><p>generations, so that they understand that science and</p><p>technology is not just about `goodies like playstations ,</p><p>mobile telephones and the internet, or `baddies like ssion</p><p>bombs, global warming or genetically modi ed crops, but a</p><p>big, mixed bag of attributes which may change our lives for</p><p>ever. The original inventors pursued their ideas, quite often</p><p>without considering the future eect of their discoveries,</p><p>because they could not possibly know what their in uence</p><p>might be, but historians of science can, and should, place</p><p>these inventions and their repurcussions within social</p><p>histories so that future generations can make up their</p><p>own minds. However, I believe that the entertainment</p><p>factor in science as social history must be writ large; there</p><p>are as many amusing, charismatic, brave people within the</p><p>scienti c community as in the general population. Science</p><p>can, and does, make a good story, and it is peopled by real</p><p>characters whose lives are as interesting, dramatic or tragic</p><p>as any ction; we just need authors who will write about it</p><p>and remind the audience that the technological advances in</p><p>their lives do not come free of personal, political or</p><p>emotional hardship; nor are new inventions free of future</p><p>moral or social dilemmas. There are issues behind all</p><p>science, even if it is only the `o button on the TV control</p><p>pad. In Dahl s book we meet real people struggling in the</p><p>chaos of real lives during a dangerous and turbulent period</p><p>in the 20th century; it tells a story which has more drama</p><p>than any TV soap opera, but curiously, has very few</p><p>villains. Science as social history? Yes please; I await the</p><p>next episode!</p><p>Essay review 127</p><p>Dow</p><p>nloa</p><p>ded </p><p>by [</p><p>Um</p><p>e U</p><p>nive</p><p>rsity</p><p> Lib</p><p>rary</p><p>] at</p><p> 04:</p><p>16 2</p><p>2 N</p><p>ovem</p><p>ber </p><p>2014</p></li></ul>
