BARC OCES/DGFS study plan

Map the Nuclear Science and Technology syllabus into a one-page topic checklist and rate each topic as strong, weak, or unknown

Derive and use the radioactive decay law, half-life, and mean-life relations to solve 15 numerical problems without notes

Distinguish fission and fusion energetics by computing Q-values for two representative reactions from mass defects

Define cross-section, flux, and reaction rate, then compute reaction rates for three sample flux and cross-section pairs

Write a 10-line summary of the nuclear fuel cycle from mining to waste, noting where each stage sits in the syllabus

Explain moderation, absorption, and leakage in a thermal reactor and state how each affects the multiplication factor

Compute the four-factor formula terms for a simplified homogeneous core given enrichment, moderator ratio, and resonance escape data

Sketch and label the main components of a pressurized heavy water reactor and a boiling water reactor and list three engineering differences

Solve 10 neutron balance and criticality problems, including one on reactivity in dollars and pcm

Summarize reactor kinetics qualitatively, covering delayed neutrons, prompt criticality, and the role of the delayed neutron fraction

Review the core equations of fluid mechanics, heat transfer, and thermodynamics and build a single formula sheet with units and validity limits

Solve 12 mixed problems combining Bernoulli, friction factor, and pump power calculations

Compute steady-state heat conduction through a slab and a cylindrical fuel-pin geometry, including a convective boundary

Derive the thermal efficiency of an ideal Rankine cycle and compare it with a reheat variant for the same steam conditions

Explain the functions of control rods, burnable poisons, and soluble boron and compare their reactivity worth and operational trade-offs

Describe three design-basis accident scenarios and the engineered safety features that mitigate each

Compute decay heat fraction at 1 s, 100 s, and 1 hour after shutdown using a standard approximation and discuss the implications for cooling

Solve 8 problems on heat removal from a fuel pin under normal and degraded conditions

Outline radiation shielding principles and estimate attenuation through a slab using a half-value layer approach

Build a physics formula sheet covering mechanics, electromagnetism, optics, and modern physics with SI units for every quantity

Solve 20 physics numericals under timed conditions at roughly 1.5 minutes per question

Summarize periodic trends, chemical bonding, and coordination chemistry in a condensed revision sheet

Solve 10 chemistry problems on stoichiometry, equilibrium, and electrochemistry

Identify your three weakest physics and chemistry subtopics from the timed set and log the error pattern for each

Solve 30 quantitative aptitude problems covering percentages, ratios, averages, and time-speed-work at exam pace

Practice 20 data interpretation questions from tables and bar charts and record time per set

Complete 25 logical reasoning items spanning series, coding-decoding, blood relations, and syllogisms

Take one 40-question aptitude mock under strict timing and classify every error as conceptual, careless, or time-pressure

Draft a personal time-allocation strategy for the aptitude section based on mock performance

Re-derive the five formulas you most often get wrong across all technical domains and solve two problems for each

Complete 40 mixed technical questions spanning nuclear, engineering, and physical sciences under timed conditions

Review every missed question from weeks 1 to 6 and rewrite the underlying concept in your own words

Consolidate all formula sheets into a single indexed reference of no more than four pages

Explain aloud, in under three minutes each, three core concepts such as criticality, decay heat, and moderator choice

Take two full-length simulated tests under exam timing and record section-wise scores for both

Analyze both mocks to identify the three highest-yield gaps and close each with a targeted 30-minute review

Rehearse the four-page formula sheet from memory and verify against the original

Finalize an exam-day plan covering section order, time checkpoints, and skip thresholds

Stop new-topic study 48 hours before the exam and use the remaining time only for revision and rest
