The release of ChatGPT has been characterized as a watershed moment for artificial intelligence (AI). The new tool’s demonstrated capabilities leave no doubt about its wide range of possible applications, from education and entertainment to language and coding assistance. Tempering the general excitement, however, are serious concerns about its potential for misuse in many domains, including academia, politics, and cybersecurity. Indeed, the AI tool may enhance the capabilities of malign actors just as it assists legitimate individuals and organizations.
The debit side of the ledger
As the developers at OpenAI have acknowledged, ChatGPT has capabilities that could be effectively abused by those who wish to circumvent the law. For instance, cyber criminals can employ the chatbot to create more advanced malware thanks to its remarkable coding ability,[2] and scammers can use it to compose phishing emails at higher quality and lower costs.[3] Similarly, disinformation written by ChatGPT is much more difficult to detect and moderate as the bot can generate infinite versions of any fake story almost instantaneously.[4] While the developers at OpenAI have acknowledged the potential for such malign use, the guardrails they have deployed are still far too easy to circumvent.[5] Moreover, ChatGPT can inadvertently corrupt legitimate applications if the user is not exceptionally attentive to the model’s limitations, one of which is its tendency to mislead. As the developers at OpenAI have explained, ChatGPT “sometimes writes plausible-sounding but incorrect or nonsensical answers” – a phenomenon known as hallucination – as there is “currently no source of truth” in its training through reinforcement learning. Hence, any application of the AI model in tasks where factuality is crucial runs the risk of distortion even if the task is well-intentioned.
What does this all have to do with the nuclear agenda?
When it comes to the nuclear agenda, AI innovations like ChatGPT promise a range of useful applications. For instance, researchers have long tried to develop natural language processing (NPL) tools for the optimization of nuclear facility operation and maintenance. One initiative launched in 2021 envisions using NPL algorithms to evaluate the tens of thousands of maintenance reports generated by nuclear power plants to identify possible component failures and near-misses while offering insights on maintenance strategy.[6] Elsewhere, AI tools are being developed for the automation of nuclear power plant operation as well as anomaly detection and inspections.[7] If done right, the improvement in economics and safety could be enormous.
However, just as AI instruments can be used to advance the nuclear agenda, they also present risks that cannot be ignored. For instance, ChatGPT’s potential to enhance the capabilities of malign cyber actors represents a serious danger to nuclear security. With the digitalization of instrumentation and control systems, nuclear facilities are increasingly vulnerable to cyber threats, including malware and phishing attacks that ChatGPT is most proficient in assisting. Testing shows, for example, that the AI model has no qualms about writing fake emails to nuclear facility employees asking for access credentials – in different languages and styles of writing as requested (see Appendix I). Indeed, it has no way of knowing whether the email is fake at all as it lacks the ability to check the user’s credentials. Upon the user’s request, the AI model will also identify common vulnerabilities in specific systems of a nuclear facility and list the malware that has been used in the past to target those systems (see Appendix I).
As far as nonproliferation is concerned, the AI model may be used by malign actors to gather information on the making of WMDs. While it will refuse an explicit request for bomb-making instructions, it can easily be coaxed into providing such information with some manipulation of the prompt. For example, researchers have tried – with success – to elicit from ChatGPT the instructions for building a dirty bomb by pretending to be researching the prevention of radiological terrorism.[8] Even if the model is trained using publicly available information only and is therefore unlikely to disclose sensitive technical information not already in the public domain, its ability to integrate public information and render it accessible across languages could still lower the knowledge barrier faced by proliferators.
A separate threat to the nuclear agenda is presented by AI-assisted disinformation. Simple tests have shown that ChatGPT will, despite initial hesitance, comply with requests to make up stories of severe nuclear accidents and theft of nuclear materials at real and specifically named facilities. Upon the user’s request, the AI model is able to integrate convincing quotes by facility managers, in addition to plausible figures describing the fictitious radioactive release and its human casualties. With minimal prompting, it is able to fabricate a detailed and coherent technical account as to the reason and nature of the accident – such as damaged fuel cladding or coolant pump failure. As always, the story can be composed in multiple languages, narrative styles, and variations (see Appendix II). If propagated by anti-nuclear politicians and activists or by commercial competitors, these compelling but false narratives regarding the safety of nuclear facilities can make it much more difficult to conduct legitimate debates about the benefits and risks of nuclear energy expansion.
Apart from malign use, inadvertent misuse is another risk posed by ChatGPT. The problem arises from the attractiveness of the chatbot to policymakers and researchers in the nuclear field as a search tool for factual information of a highly complex and technical nature. There will be an understandable temptation to rely on a ChatGPT-like tool because of its phenomenal search power and speed and the fact that the AI model may appear quite adept at gathering technical facts. For example, ChatGPT proved capable in testing to present a surprising number of accurate facts related to U.S.-Russia arms control treaties and was able even to maintain its neutrality when discussing the countries’ respective responsibilities involving compliance and treaty termination. Similarly, when tested for knowledge in the nuclear energy sphere, the AI model was able to perform such tasks as providing a plausible design for a molten-salt reactor and identifying fuel suppliers for the Russian VVER.
Unless one is exceptionally well-versed about the specifics, however, it is hard to know with much confidence whether the chatbot is providing objective and accurate information. This shortcoming is the result of limitations and biases in the source material, which varies depending on the language in which the question is asked. In addition, the AI model is inclined to conceal uncertainty and instead embellish falsehoods with hallucinated details. A fictitious nuclear fuel fabrication plant may be described with a plausible location, completion date, annual capacity, director, and client – indeed with so much detail (see Appendix III) that even extremely knowledgeable experts may begin to doubt their recollections. When pressed on the facts, the chatbot will generate sources complete with dates and links to the websites of trustworthy institutions, despite the fact that they have never published the sources being identified. In short, the AI model is programed to fabricate convincing falsehoods and double down on them before it is ever willing to admit its own ignorance. If such inaccuracies are ever integrated inadvertently into critical research, fact-checking will become exponentially more difficult.
What is to be done?
In response to the risks ChatGPT poses to information integrity, some institutions have adopted a Luddite approach and banned its use for research purposes.[9] But AI tools like ChatGPT are constantly improving and will become increasingly appealing to users, rendering denial strategies futile. Moreover, as the chatbot evolves and becomes more sophisticated, omnipresent, and omnipotent, it will become increasingly difficult to detect AI-generated misinformation and disinformation. Like it or not, the impulse of rejection must give way to adaptation and damage limitation.
On the one hand, powerful fact-checking techniques (probably also AI-reliant) must be developed and deployed to counter misinformation and disinformation and to bolster the integrity of research and analysis in the nuclear field. On the other hand, nuclear researchers in various sub-fields must explore how best to utilize tools similar to ChatGPT. One approach is to devise guidelines and best practices within each sub-field, including identification of tasks for which AI is best suited and those where greater caution must be observed. Another approach is to “fine-tune” a generic tool like ChatGPT with additional training to create an AI model with task-conducive values and behavior.[10] If accuracy is more important than creativity in tasks related to nonproliferation research, for instance, it may be desirable to develop a fine-tuned AI model that is more cautious in its response behavior, that is, more inclined to stick to the script and admit ignorance rather than hallucinate. In fact, OpenAI is already exploring ChatGPT’s transformation into a customizable AI model whose values and behavior can be defined by the user.[11] Taking such a step, however, requires caution as customizable AI tools also may be adapted more easily to malign applications. The bounds of customization, then, must be circumscribed, giving rise to a whole new dimension of issues related to AI regulation and export controls, both for nonproliferation purposes and otherwise.
Such open-ended discussions inevitably raise more questions than they are able to answer. But one observation seems uncontroversial. ChatGPT presents both opportunities and challenges to the nuclear agenda. As such, it illustrates what the international nuclear community has long recognized, namely, the potential of AI – and other disruptive technologies – to advance the field[12] while simultaneously raising new and complex problems. Given the high stakes involved, the nuclear community would do well to carefully consider its response and, as with any new technology, strike the right balance between enthusiasm and caution.
