We have been living in the nuclear age now for over half a century. Since the first atomic bombs were developed, nuclear technology has provided governments with the ability to totally destroy the planet. Yet the technology has been put to positive use as an energy source and in certain areas of medicine. To what extent is nuclear technology a danger to life on Earth? What are the benefits and risks associated with its use?
Sample Response
Since the inception of humanity, energy has been like oxygen to mankind. As said in the famous saying necessity is the mother of all inventions, man has created many new forms of energy to cater to his needs. To generate the continuous supply of energy we have been using non-renewable resources. Nuclear energy has emerged as a clear alternative to the conventional non-renewable resources which are depleting at an accelerating rate. But, with its hugely rewarding merits, it has proven itself as a dangerous alternative which can be fatal if placed in wrong hands.
The nuclear emission can be fatal to the living organisms and thus the production and consumption have to be done with a lot of caution. For instance, the USA used nuclear weapons on Japan, Hiroshima Nagasaki. We can never forget the horrendous mass destruction it caused and the after effects present till date. Since then, the world super powers have reached many agreements to not repeat such usage of nuclear technology which can threaten the life on earth. Furthermore, the Tsunami in Japan brought Japan and its neighbours at a high risk due to emissions from the impacted Nuclear Energy plant.
While the dangers of nuclear technology are well known and measured, the advantages it provides are huge too. The Amount of energy it can generate can make a country self-sufficient for its energy needs. Countries like Japan have realised this and are now generating the nuclear energy on large scale. Japan has ensured that all the safety precautions are addressed to marginalise the dangers.
Since every scientific invention has proved to have two facets, Nuclear energy can prove to be an answer to the energy problem of the world, provided it is used wisely. All the countries, small or big, must come together and work towards using the Nuclear Technology as a tool of development.
IELTS Writing Correction
- 1. Overstated analogy Original: energy has been like oxygen Suggested revision: energy has been essential Why it matters: This is more precise for an academic essay.
- 2. Quote punctuation Original: As said in the famous saying necessity Suggested revision: As the saying goes, 'necessity Why it matters: Introduce and punctuate the quotation correctly.
- 3. Missing article Original: continuous supply of energy Suggested revision: a continuous supply of energy Why it matters: Supply is a singular count noun.
- 4. More precise contrast Original: conventional non-renewable resources Suggested revision: fossil fuels Why it matters: Nuclear fuel is also non-renewable, so the original contrast is inaccurate.
- 5. Redundant phrase Original: hugely rewarding merits Suggested revision: substantial benefits Why it matters: Merits already means benefits.
- 6. Missing article Original: in wrong hands Suggested revision: in the wrong hands Why it matters: This fixed expression requires the.
- 7. Technical precision Original: The nuclear emission Suggested revision: Radiation exposure Why it matters: This accurately names the danger to organisms.
- 8. Remove article Original: living organisms Suggested revision: living organisms Why it matters: No definite article is needed for organisms in general.
- 9. Wrong process terms Original: production and consumption Suggested revision: production and use of nuclear technology Why it matters: Radiation itself is not consumed in the intended sense.
- 10. Location wording Original: Japan, Hiroshima Nagasaki Suggested revision: the Japanese cities of Hiroshima and Nagasaki Why it matters: Name the two cities with a conjunction.
- 11. Natural time phrase Original: after effects present till date Suggested revision: long-term effects that persist today Why it matters: This is clearer and more formal.
- 12. Compound noun Original: world super powers Suggested revision: world's superpowers Why it matters: Use the possessive and closed compound.

Why this response received Band 6.5
The essay maintains a balanced view, explains major weapons and accident risks, and identifies nuclear power's capacity to provide large-scale energy. It does not address medical benefits and offers limited analysis of the extent of danger, while recurring collocation, capitalization, and article errors reduce precision; prioritise complete coverage of all prompt elements and more exact technical language.
IELTS Writing Criteria Scores
Detailed feedback by IELTS writing criterion after the annotated essay.
Task Response
Risks and energy benefits are relevant and supported, but medical applications are omitted and the degree of danger is not explicitly assessed.
State the conditions under which nuclear technology poses an existential, regional or manageable risk, and add a medical benefit.
Coherence and Cohesion
The four-paragraph structure progresses logically from position to risks, benefits and conclusion.
Use clearer internal topic sentences and avoid spending too much of the introduction on general energy history.
Lexical Resource
There is adequate topic vocabulary, but several technical collocations and word forms are inaccurate.
Use precise phrases such as 'radiation exposure', 'nuclear power plant', 'mitigate risks' and 'in the wrong hands'.
Grammatical Range and Accuracy
Complex sentences are generally understandable, though articles, capitalization and punctuation errors recur.
Check proper nouns, common nouns and article use, and punctuate introductory phrases and quotations carefully.
